Here is some infos about an OMG compatible sensor the SONOFF PIR2 sensor
It looks more modern compared to the other PIR sensor we have seen before, it has a blue led light in the front and pet immune.
It sends one signal when triggered, the protocol used is compatible with:
- ZgatewayRF (ESP32 or ESP8266 with an RF receiver)
- ZgatewaySRFB (Sonoff RF Bridge)
When sending signal 6mA during around 2s
Sleep current 14uA continuously

This sensor is very well optimized in term of power consumption, it is among the top of the list of the energy savy devices!
It should last several years.
