The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

This project demonstrates how to use an IR sensor with an Arduino to detect obstacles. The IR sensor can be used for various applications such as obstacle avoidance, line following robots, and more.

Old infrared remote controls can be a great way to interface with your projects. One of [AnalysIR’s] latest blog posts goes over the simplest way to create an Arduino based IR receiver, making it ...

LEDs on the Arduino can be programmed to indicate if the sensor is/isn’t immersed by the liquid (and thus determine if liquid level is too high/low). The two companies say that the hardware provides ...

The smart car parking system uses an ESP32 microcontroller, an IR sensor, a servo motor, and an Arduino Cloud account to efficiently manage parking spaces, reduce traffic congestion, and improve air ...

[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 ...
