Wanted to integrate a PIR sensor into your home automation solution but it is too much of struggle to solder a sensor then get it talk to your home automation system.
Sonoff has got you covered with their PIR2 motion sensor that can detect human movement and works over 433Mhz's RF.
The sensor makes use of passive infrared technology to detect motion either during the day or the night with a wide viewing angle of up to 110 degrees and a detection range of up to 12m.
This sensor can not only be used for security but also to switch your lights on or off or whatever it is your maker mind can think of.
Ah but it is so much hassle to draw wires to connect the sensor to power. Not required, the PIR2 sensor works with 2 AA batteries (not included) and can last up to 2 years.
Remember this uses RF so an Sonoff RF Bridge is required to connect it to your WIFI network.
