Working Principle The IR sensor emits infrared light from an LED. When an object comes into range, the emitted light reflects back to the sensor’s receiver module. Based on the intensity of the ...

Testing the E18-D80NK IR Sensor Once your code and hardware are ready, connect Arduino to the laptop and upload the code. After that open the serial monitor at a baud rate of 9600, and make some ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

These modules, typically seen in line following robots, are ideally suitable for white/black line detection. You can also see them in certain entry alarm systems. HW-006 Module – A Brief Overview The ...

Let see how to make Arduino based digital Tachometer. Working principle :- IR Sensor get penetrate by motion of motor shaft, signal are transfer from IR Senor module to Arduino. This signal are ...

Designed to receive IR pulses from an emitter with a peak wavelength of 940 nm, the sensor module operates at a supply voltage range from 2.5 V to 5.5 V, features a low supply current of 0.7 mA ...
