Hanwell RFBug Wireless Sensor


Temperature and humidity radio transmitter for Hanwell wireless systems

Hanwell’s RFBug is part of Hanwell’s advanced series of temperature and humidity radio transmitters. They allow wire-free monitoring of a site, with real-time alarm notification and historical analysis of data. Each unit reads on-board sensors to provide accurate and reliable information about environmental conditions. This data is transmitted, at user-defined intervals, to the Radiolog system where it is filed for analysis.

The RFBug has a precision temperature sensor and a high quality humidity sensor. Transmitter ID number and transmission rate are set using dip switches accessible through the back of the case.

Temperature and humidity are closely interrelated. Some independent effects of high temperature and humidity include increased biological activity, and acceleration of chemical deterioration processes.
