Did you consider radar[0] instead of PIR with the MPS430?

- davekeck 2y agoOhh fancy! No I didn't consider radar, watching that video now. The main consideration for the motion sensor is power consumption -- Photon's PIR consumes ~2µA. Any idea what the power consumption is for these radar sensors?
- adolph 2y agoSpeiss’ videos are good about measuring current. He was an early one on the coin operated ESP8266 movement. Looks like they are outside your energy budget: 2.3mA is the lowest. The video I linked was from 7 years ago? Here is a more recent one but it doesn’t seem like he measured energy consumption: https://youtu.be/s-GzUTyIH9c https://youtu.be/s-GzUTyIH9c As validation of your PIR-Cam idea, LilyGo sells a PIR-Cam-SSD1306 combo board: https://www.lilygo.cc/products/t-camera-s3 https://www.lilygo.cc/products/t-camera-s3
