An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

The HC-SR501 Infrared sensor will detect Infrared changes and if interpreted as motion, will set its output low. What is or is not interpreted as motion is largely dependent on user settings and ...

There is only one common solution for this problem: Modulate your IR signal so that your sensor can detect an IR variation rather than a fixed IR level. In this tutorial, we are going to interface E18 ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...

The Arduino Uno IR Sensor detects infrared (IR) radiation emitted by objects. It typically includes an IR transmitter and receiver pair, with the receiver detecting reflected IR light. This enables ...

This project-based on Arduino Uno and IR sensors is used to automatically switch on and switch off a washroom’s light that works on AC mains. Whenever a person enters the washroom, the light bulb (or ...
