Wireless amplified Sensor of Temperature, Humidity and Light
The KET-THL-200 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 amplified sound module allows to reach distances of over 600m in free air.
KET-THL-200 comes with an internal memory, which allows you to store over 60,000 information, in case of malfunction of wireless network, retransmitting the data automatically as soon as possible.
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 four years with ordinary alkaline batteries.
