jaky je rozdíl mezi tímto levnějším senzorem a úplně stejný, o 100kc dražším a označeným nobattery?? nejde mi to do hlavy...

Recording movement is one of the basic elements of a smart home. Depending on the captured activity in the given space, it is possible to activate an alarm, turn on the lights or, on the contrary, silently turn on the camera recording. Thanks to the Sonoff SNZB-03 ZigBee Motion Sensor, you can also learn about everything immediately directly in the mobile application.

The Sonoff SNZB-03 ZigBee Motion Sensor senses the entrusted space at an angle of 110o and can detect movement up to 6 meters. Its ideal location is somewhere near the ceiling or in the corner of the room so that it can scan, for example, a window or a door. Then not even a mouse will slip in the area.
The Sonoff SNZB-03 ZigBee Motion Sensor button is powered by a small CR2450 battery. However, thanks to the use of the ZigBee 3.0 wireless standard, the operation is completely energy-efficient. If the battery charge level is close to zero, the eWeLink mobile application will notify you in good time.
