The FIBARO Universal Binary Sensor is a unique wireless module for enhancing the functionality of any existing binary output system. The sensors enable such devices to communicate wirelessly with the FIBARO smart home system. The module also functions as a wireless temperature sensor system when connected to the DS18B20 temperature sensors. Each module can service up to two binary sensors and four DS18B20 temperature sensors. The Sensor was designed for installation inside the housing of another device whose functionality is to be enhanced (e.g. an alarm PIR sensor). The Universal Binary Sensor is ideally suited for the wireless collection of data from other sensors. Once the appropriate additional safety housing have been installed, the sensor can be used in areas with high humidity and temperature. The sensor is often used for integrating the FIBARO system with existing alarm and measurement systems. Its sits in line and is completely transparent to the instrumented system thus allowing it to function normally as before.
