Wireless Temperature, Humidity and Light sensor for outdoor use
The KET-THL-200.S is a wireless sensor suitable for outdoor positioning thanks to the high degree of protection of the container and to the temperature and relative humidity sensors protected from atmospheric agents. It also integrates a light sensor for complete environmental monitoring.
The high sensitivity of the amplified sound module allows to reach distances of over 600 m in free air.
KET-THL-200.S 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 five years with ordinary alkaline batteries.
