The IRTR module presented here features a fixed-gain, 38-KHz modulated infrared receiver and a corresponding infrared sender with oscillator circuit to make cool infrared projects such as a tiny ...

This burglar alarm system circuit is using a infrared proximity detector that triggers an alarm when the rays falling on its sensor are interrupted. It is different from others burglar alarm systems ...

Learning about how infrared ... build a couple of circuits to experiment with and communicate through infrared light transmissions. Instead of going with an IR receiver module you’ll build ...

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 ...

At the heart of the circuit lies a CNY70 reflective opto sensor module ... The LED emits infrared light, and the phototransistor works as a receiver. When the opto sensor is illuminated, four ...

Specified for 3V operation, the TSOP34838SS1A infrared (IR) receiver module is capable of operating on voltages down to 2.4V at a distance of up to 35m. The device integrates both a photo detector ...
