Wireless Sensor of Temperature, Humidity and Light in ZigBee technology

The KET-THL-100 combines a light sensor and a digital sensor for temperature and relative humidity in a compact size device, creating a comprehensive environmental monitoring.

The high sensitivity of the radio module allows to reach distances of over 100 m in free air.

The LinkQuality feature indicates the actual quality of radio reception to allow rapid positioning of the device.

When a signal arrives, the Diversity system selects the antenna with the highest gain thus increasing the radio sensitivity.

The battery life is greater than two years with ordinary alkaline batteries.
