An infrared sensor is an electronic module that is used to detect the certain physical appearance of its surroundings by either emitting and/or detecting infrared radiation. IR sensors can also sense ...

This repository contains a Python script designed for the Raspberry Pi 4 that uses an infrared (IR) sensor to detect obstacles. When an obstacle is detected, the system activates an LED and a buzzer, ...

The current COVID-19 scenario needs no introduction. While everyone is giving their best to move forward, it is important to act responsibly and tackle this problem collectively. Today in many public ...

Take a Si1120 Ir-LED sensor and seven infrared LEDs. Add in one ultra-low power C8051F930 MCU. Mix thouroughly. The result is Silicon Labs' $199 Si1120 Evaluation Kit. It could also be your next 3D ...

The IR photodiode is sensitive to the IR light emitted by an IR LED. The photo-diode's resistance and output voltage change in proportion to the IR light received. The IR sensor is controlled under ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

[RiverTechJess] is in the process of getting a PhD in environmental engineering and has devoted a chapter to creating a turbidity sensor for river network monitoring. Environmental sensing benefits ...
