In the microcontroller era today, Arduino ... at its sensor input port. As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion ...

Recently [Glen Akins] reported on Bluesky that the Zigbee-based sensor he had made for his garden’s rear gate was still going ... would just have put in a PIR sensor-based solution, this Zigbee ...

When something passes in front of a PIR sensor it detects the change in background temperature and then triggers an output voltage. This voltage can be read by an Arduino digital input and then ...

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 ...

But if you use two PIR sensors you can monitor a focused area for motion. The trick is to use a logic circuit. By building an AND gate you can trigger based on motion in the area which is ...
