Review on π’ Onyehn IR Pyroelectric Infrared PIR Motion Sensor Detector Modules DC 2.7 to 12V(Pack of 5pcs): Enhance Your Security with Reliable Motion Detection by Maurice Stavros
Good: works at 3.3V Bad: 2 out of 5 does not work
The good news is that they work at 3.3V directly, so perfect for NodeMCU with ESPeasy. The bad news is that they are horribly soldered - even I could do better. 3 out of 5 worked, 2 didn't work. This significantly increases the cost of a single (working) device.
- Elegant design
- Long delivery time
