SONOFF PIR3RF – 433MHZ RF PIR motion sensor

PIR3RF has 2 working modes that alert and normal mode. In the alert mode, the sensor is triggered per 5s when someone enters the detection range. In the normal mode, the next alert trigger is activated if there is no motion detected within 1min after the previous detection. Note: 1. The PIR3RF sensor requires SONOFF 433MHz RF Bridge to work. 2.


Connecting a 433MHz receiver to ESP8266? Arduino Forum

May 21, 2021· I have a need to monitor and log temperature and humidity in several places in my house and I have wired up 3 AM2302 DHT sensors in the attic. But now I also need to connect to a few extra sensors that cannot be wired in to the ESP07 unit, so I cannot use the DHT sensors. So I figured that if I use commercial wireless sensors operating on 433MHz it could be possible to connect to them and ...
