ZigBee sensor for temperature, humidity and light
This device may be configured to manage alarm thresholds for exceeding maximum or minimum levels of measures. It is also possible to adjust the sampling and data transmission rate to improve battery life. The sensors are protected into a plastic material case such as Gore-Tex in order to let only air entering and no water. Because of its high degree IP protection, ZED-THL-M can also be used outdoor.
