Temperature monitoring — for many years

One RF Technology has developed a low-power wireless temperature monitoring solution using ZigBee and offering many years of autonomous operating time with a standard lithium AA battery.

The system consists of a coordinator, one or multiple routers depending on the size of the installation and up to 1000 sensors. The data collected from the sensor network is transmitted to a central unit for monitoring and control.

Alarm signals for deviations from the predefined temperature range can be programmed for extra security and ensure consistent product quality.

This allows users to monitor and control the temperature of refrigerators and cold storages 24 hours a day, automatically and without maintenance.

The temperature monitor is based on the company’s TinyOne radio module and the low-power mesh networking firmware — M-One Stack. The 868 MHz frequency used facilitates the wireless data transmission through multiple walls within a building, combining long range with low power consumption.

Depending on the data transmission frequency, the system offers up to 10 years' battery life with a regular lithium AA battery.
