Also note that we have covered the IR LEDs on the sensor with a black tape to make it point only forward, we will discuss more about that later. If you are completely new to IR sensors and wish to ...

A quick search found several versions of infrared line tracker sensor modules that met or exceeded my demands, but I picked the cheap YL-70 4-channel line tracker module! The YL-70 line tracker sensor ...

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 ...

The hardware design involves the design of the sensor nodes, processor, communication and WSN architecture. The program for the sensor node processor stage and base station receiver processor was ...
