Hall Effect Sensor Module is used to Detect the proximity of a magnet. It is very much Smaller in size. When the magnetic field rises above a threshold level, the open-collector output transistor switches on, which pulls the logic-compatible output low and illuminates the on board LED indicator.

Its fast (The turn-on threshold is 35-450 Gauss, the minimum hysteresis is 20 Gauss, and the operating voltage range is 4.5 - 24 volts.This module uses the Allegro MicroSystems A3144EUA sensor. It has a 3 pin interface, signal, V+ and GND.

To use this sensor/switch, place a 10K pull-up resistor between the "S" pin and the middle pin (+), connect the "-" pin to ground. Supply voltage to the middle pin. The "S" pin will go low (gets pulled to ground) and the on board LED indicator will turn on when a magnet is brought near.

The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature.Since it has Linear + 10.0 mV/°C scale factor it is very easy to calculate temperature value.

The LM35 thus has an advantage over linear temperature sensors calibrated in ° Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming to provide typical accuracies of ±1⁄4°C at room temperature and ±3⁄4°C over a full −55 to +150°C temperature range. Low cost is assured by trimming and calibration at the wafer level. The LM35's low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy. It can be used with single power supplies, or with plus and minus supplies. As it draws only 60 μA from its supply, it has very low self-heating, less than 0.1°C in still air.

The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the output of the module is low, lower power consumption; When a finger touches the corresponding position, the output of the module is high, if not touched for 12 seconds, it switches to low-power mode. Jog type: the initial state is lower, higher touch, do not touch is lower.

This Module can be installed in such as surface plastic, glass of non-metallic materials. In addition to the thin paper (non-metallic) covering the surface of the module, as long as the correct location of the touch, you can make it hidden in the walls, desktops, and other parts of buttons.

Features:

• Low-level output signal used for human body touch sensor alarm
• Low power consumption.
• Can replace the traditional touch of a button.
• Single-channel signal output
• Adjustable sensitivity
• Four M2 screws positioning holes for easy installation.

Tilt sensor works on a similar principle of mercury switches (but is it not mercury type sensor) and also known as tilt switches, inclinometer, and rolling ball sensors. The sensor measures the tilt, orientation, and inclination in different axes in reference to a plane. It measures the tilt in reference to gravity and enables the easy detection of inclination and orientation. The sensor is very simple to use as has a digital output and an M3 mounting hole to mount with the object. It uses SW-460D/SW-520D sensor to detect tilt.  ​

Applications:

• Vibration detecting
• Analog as well as digital output
• Burglary protection system 
• Object Movement detecting
• Triggering effect reported theft alarm
• Smart car
• Earthquake alarm
• Motorcycle alarm
