Comes in compact plastic box with foams for better mobile storage

Applications

• Water quality testing
• Aquaculture

Note: This is a laboratory probe, it can’t be immersed in the liquid for a too long time.

Step to Use the pH Meter:

Cautions:

• Please use an external switching power supply, and the voltage as close as possible to the +5.00V. More accurate the voltage, higher the accuracy!
• Before the electrode in continuous use every time, you need to calibrate it by the standard solution, in order to obtain more accurate results. The best environment temperature is about 25 ???, and the pH value is known and reliable, close to the measured value. If you measure the acidic sample, the pH value of the standard solution should be 4.00. If you measure the alkaline sample, the pH value of the standard solution should be 9.18.Subsection calibration, just in order to get better accuracy.
• Before the pH electrode measured different solutions, we need to use water to wash it. We recommend using deionized water.

1. Connect equipment according to the graphic, that is, the pH electrode is connected to the BNC connector on the pH meter board???and then use the connection lines, the pH meter board is connected to the analog port 0 of the Arduino controller. When the Arduino controller gets power, you will see the blue LED on board is on.
2. Upload the sample code to the Arduino controller.
3. Put the pH electrode into the standard solution whose pH value is 7.00???or directly shorted the input of the BNC connector. Open the serial monitor of the Arduino IDE, you can see the pH value printed on it, and the error does not exceed 0.3. Record the pH value printed, then compared with 7.00, and the difference should be changed into the “Offset” in the sample code. For example, the pH value printed is 6.88, so the difference is 0.12. You should change the “# define Offset 0.00” into “# define Offset 0.12” in your program.
4. Put the pH electrode into the pH standard solution whose value is 4.00. Then wait about one minute, adjust the gain potential device, let the value stabilize at around 4.00. At this time, the acidic calibration has been completed and you can measure the pH value of an acidic solution.
   

Note: If you want to measure the pH value of other solutions, you must wash the pH electrode first!

• According to the linear characteristics of the pH electrode itself, after the above calibration, you can directly measure the pH value of the alkaline solution, but if you want to get better accuracy, you can recalibrate it. Alkaline calibration uses the standard solution whose pH value is 9.18. Also, adjust the gain potential device, let the value stabilize at around 9.18. After this calibration, you can measure the pH value of the alkaline solution.

2. Small and Compact module
3. Easy to use.

This KY-039 Finger Detection Heartbeat Measuring Sensor Module uses bright infrared (IR) LED and a phototransistor to detect the pulse of the finger, a red LED flashes with each pulse.

The LED is the light side of the finger, and the phototransistor on the other side of the finger, phototransistor used to obtain the flux emitted, when the blood pressure pulse by the finger when the resistance of the phototransistor will be slightly changed.

We chose a very high resistance resistor R1 because most of the light through the finger is absorbed, it is desirable that the phototransistor is sensitive enough. Resistance can be selected by experiment to get the best results. The most important is to keep the shield stray light into the phototransistor.

QUICK OVERVIEW

The FlexiForce A201 force sensor is an ultra-thin and flexible printed circuit, which can be easily integrated into most applications.

The FlexiForce A201/1 flex sensor is an ultra-thin and flexible printed circuit, which can be easily integrated into most applications. With its paper-thin construction, flexibility and force measurement ability, the FlexiForce force sensor can measure force between almost any two surfaces and is durable enough to stand up to most environments. FlexiForce has better force sensing properties, linearity, hysteresis, drift, and temperature sensitivity than any other thin-film force sensors.

The “active sensing area” is a 0.375” diameter circle at the end of the sensor. The sensor has two layers of the substrate. This substrate is composed of polyester film (or Polyimide in the case of the High-Temperature Sensors). On each layer, a conductive material (silver) is applied, followed by a layer of pressure-sensitive ink. The adhesive is then used to laminate the two layers of substrate together to form the sensor. The silver circle on top of the pressure-sensitive ink defines the “active sensing area.”

Silver extends from the sensing area to the connectors at the other end of the sensor, forming the conductive leads.
FlexiForce sensors are terminated with a solderable male square pin connector, which allows them to be incorporated into a circuit. The two outer pins of the connector are active and the centre pin is inactive. The length of the sensors can be trimmed to predefined lengths of 2”, 4” and 6” as per the requirements. If the sensor is trimmed, a new connector must be attached. This can be accomplished by purchasing staked pin connectors and a crimping tool. A conductive epoxy can also be used to adhere to small wires to each conductor.

The sensor acts as a variable resistor in an electrical circuit. When the sensor is unloaded, its resistance is very high (greater than 5 Meg-ohm); when a force is applied to the sensor, the resistance decreases. Connecting an ohmmeter to the outer two pins of the sensor connector and applying a force to the sensing area can read the change in resistance.

Application:

An example circuit is shown below. In this case, it is driven by a -5 V DC excitation voltage. This circuit uses an inverting operational amplifier arrangement to produce an analog output based on the sensor resistance and a fixed reference resistance (RF). An analog-to-digital converter can be used to change this voltage to a digital output. In this circuit, the sensitivity of the sensor could be adjusted by changing the reference resistance (RF) and/or drive voltage (VT); a lower reference resistance and/or drive voltage will make the sensor less sensitive and increase
its active force range.

 

Note:

The sensing area is the silver circle on the top of the sensor only.

Typical Performance:

1. Force Range: 0-1 lb (4.4 N)
2. Operating Temperature Range: 15°F to 140°F (-9°C to 60°C)
3. Linearity (Error):  +/- 3%

5. Hysteresis: <4.5% of full scale (conditioned sensor, 80% force applied)

7. Response Time: <5 microseconds
8. Output Change/Degree F: Up to 0.2% (~0.36% / °C).
   Loads <10 lbs, the operating temperature can be increased to 165°F (74°C).

This is a force sensitive resistor with a square, 1.75 x 1.5″, sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ.

This FSR can sense applied force anywhere in the range of 100g-10kg. Two pins extend from the bottom of the sensor with 0.1″ pitch making it bread friendly. There is a peel-and-stick rubber backing on the other side of the sensing area to mount the FSR.

Just Connect a resistor to form a voltage divider and measure the voltage at the junction to find the force applied. These sensors are simple to set up and great for sensing pressure, but they aren’t incredibly accurate. Use them to sense if it’s being squeezed, but you may not want to use it as a scale.

HB100 Microwave Doppler Radar Sensor is an X-Band Bi-Static Doppler transceiver module. It has a built-in Dielectric Resonator Oscillator (DRO) and a pair of Microstrip patch antenna array, making it ideal for usage in motion detection equipment.

This module is ideal for alarms, motion detectors, lighting control, vehicle speed measurement, and automatic doors.

Doppler Principle

Doppler theory based on time. when radio waves encounter an object in the moving process will be reflected when the waves. the frequency of the reflected wave will hit the object with the movement to change state. If the radio waves encounter an object position is fixed. then the reflected wave frequency and transmitting frequency waves should be equal. If the object moves toward the launch. then the reflected waves will be compressed. that will increase the frequency of the reflected wave; otherwise, the reflected wave’s frequency decreases.

Note: Please use a low voltage soldering iron and connect it to a reliable grounding. This device is sensitive to ESD and it may be damaged during soldering. The IF output of the HB100 module is especially sensitive. You can check it for damage using a multimeter in diode mode. The forward voltage drop between IF and GND should be about 0.25 V.

5. Maximum Power : 230 W
6. Power Cord: 25cm.

The TEC1-12715 40x40mm Thermoelectric Cooler 15A Peltier Module is the simple application of Peltier Thermoelectric Effect. The module features 127 semiconductor couples in the area of 40mmx40mm.

Thermoelectric coolers also are known as TEC or Peltier Module create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity.

This Peltier works very well as long as you remove the heat from the hot side. After turning on the device, the hot side will heat quickly, the cold side will cool quickly. If you do not remove the heat from the hot side (with a heat sink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or another block of metal to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortable we could not hold our finger to it.

A thermoelectric cooling (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying the DC power source to a TEC, heat will be transferred from one side of the module to the other. It creates a cold and hot side. They are widely used in industrial areas, for example, computer CPU, CCDs, portable refrigerators, medical instruments, and so on.

Also Known as Thermoelectric cooling modules, Thermoelectric modules, Peltier modules, Thermoelectric cooling module.
