Suitable for SONOFF SNZB-03 and SONOFF PIR3-RF. Thanks to the universal joint, the sensor can be flexible to rotate 360 ° horizontal angle and 90 ° vertical angle, allowing you to set the sensor to the optimal angle so that you can watch everything in your home (the sensor does not move itself based on your movement). Another advantage for your home is that you can use the sensor in a position where motion is not easy to detect, by mounting it in a universal joint, and only rotate the head of the universal joint to get an amazing detection angle.
