The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close ... Simply put, unlike ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared ... most PIR sensors (like the one above) come in a simple-to-interface module containing all the support ...

I needed a multichannel line tracker sensor module for an upcoming ... touch-free toggle switch using an Arduino Uno. This can be used to control external electric loads by waving your hand in front ...

To replicate Krejci’s design, you need an Arduino UNO Rev3 board, an AMG8833 infrared sensor module, and an 8×8 RGB LED matrix. The device collects 64 values from the infrared sensor and uses ...

STMicroelectronics' TMOS sensors handle presence sensing using a 5- to 20-µm passive IR sensor. This provides ... the need for a cover lens. The module can detect object up to 4 m away without ...
