Introduction This is an edge detection sensor from DFRobot. It will help your robot detect the edge of a precipice, preventing it from falling off a table or down the stairs to it's certain demise!

Note: 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 power switch with infrared proximity sensor is intended for the recognition of obstructions at distances of a few millimetres to a few centimetres. This compact sensor switch can be used to open a ...

This Arduino-based project simulates a two-floor elevator control system. The elevator uses IR sensors to detect the current floor and a single button to switch between floors. A seven-segment display ...

The HDMI switch is equipped with an infrared sensor as the only means of controlling it, so naturally, that was the path chosen for interfacing the ESP32 put inside the switch.

An IR liquid level sensor works similar to an IR light barrier, with a transparent plastic cover. When the sensor comes into contact with liquid, the refraction at the interface changes, and with it ...
