Review on HiLetgo 3pcs AM312 Mini Pyroelectric PIR Human Sensor Module Infrared IR Sensor Body Manual Motion Infrared IR Detector by Tres Carmon
Works well in the HF range. Inexpensive. Large supply voltage range.
According to a renowned YOUTUBER and Arduino S/W & H/W engineer, he believes that RF radiation from a nearby device can cause IR devices to become unstable. I tried a lot, but only AM312 worked stably. It's inexpensive and runs on both 3.3V and 5V. It's also small. The only complaint I have is that the 3.3V sensitivity can only detect motion 3-4 feet away. I think for further distance measurements one should consider a higher (5V etc.) supply voltage or a larger lens window.
