Interfacing a Bare PIR Sensor with Arduino – Can It Be Done. Posted: June 23, 2025 | Last updated: June 23, 2025. Hi, I'm Bill. I'm a software developer with a passion for making and electronics.

The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something. Note that after powering the PIR sensor module, it needs about 10 to 60 ...

“To create this smart device, Robert used an Arduino Oplà IoT Kit, as it contains a MKR WiFi 1010, a MKR IoT Carrier with a built-in screen and capacitive buttons, and a PIR sensor for ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.
