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 ...

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 ...

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 ...
