ZigBee ZED-THL-M Sensor for temperature, humidity and light

The ZED-THL-M drill is a ZigBee battery supplied device which can measure at the same time temperature, humidity and brightness and regularly send the collected information toward one of the gateways of the 4-noks range.
Is possible to set the device in order to manage alarms to ring when its limits are trespassed, because of an exceeding value or of a too small value. It is also possible to schedule the sampling timing and the sending modalities of the measurements in order to increase the duration of the battery.
Sensors are located in a compartment made of a plastic material similar to Gore-Tex that allows the air to pass but not the water, thus reaching such an high IP protection level that the drill can also be employed outdoor.
