The motion sensor with infrared detection technology is complemented by an integrated luminosity sensor, which makes the device even more useful. Directly connected to the input of all the Zennio devices that include motion sensor as an option in their inputs module (see the datasheet of the device). Motion detection area can be increased by installing two sensors in parallel to the same input. Easy installation and small size. It does not require any other type of connection or power supply.* This accessory must be connected to an input of a Zennio device. To find out if a device is compatible with this accessory, consult the data sheet of the device in question.
