Description:-

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.

This TCRT5000 Single Channel Line Tracking Sensor Module is a great detector for a line-following robot. Potentiometer to adjust the sensitivity of the individual sensors.

TCRT5000 Single Channel Line Tracking Sensor Module is a carrier board for TCRT5000 reflective optical sensor. Although it is designed for use with line-following robots, it can be used in mini-sumo robots for line control. The board has a digital output.

The concept of working of line follower sensor is related to light. We use here the behavior of light at the black and white surface. When light fall on a white surface it is almost fully reflected and in case of black surface light is completely absorbed. This behavior of light is used in building a line follower sensor.

Each phototransistor is connected to a pull-up resistor to form a voltage divider that produces an analog voltage output between 0V and VIN (which is typically 5V) as a function of the reflected IR. The lower output voltage is an indication of greater reflection.

 

Features :

1. Working voltage of 5V, the output of the black line low, white line of high output
2. Uses Infrared Light to Detect Anti-Interference Ability
3. Sensors to adopt TCRT5000 High Sensitivity, Stable Performance
4. Exquisite workmanship, with the indicator
5. Has a fixed bolt hole for easy installation

Package Includes :

1 xTCRT5000 Single channel line trackingsensor module.

This is a dual axis high quality JoyStick Module . It can be used to sense movements in 2 directions(axes). It also has a inbuilt switch which can be activated by pressing the stick.Directional movements are simply two potentiometers - one for each axis. Pots are ~10k each. 

With the help of this Joystick Module, you can measure position coordinates on the X and Y axis by moving the "hat". It also contains a switch that is press-able by pushing the "hat".It also contains a switch that is press-able by pushing the "hat" down. Similar to the XBOX controller.

The X and Y axes are two 10k potentiometers which control 2D movement by generating analog signals. When the module is in working mode, it will output two analog values, representing two directions. This module uses the 5V power supply, and value, when reading through analog input, would be about 2.5V, a value will increase with joystick movement and will go up till maximum 5V; the value will decrease when the joystick is moved in other direction till 0V.
