RF Code R155 Humidity-Temperature Sensor

RF Code’s R155 Humidity-Temperature Sensor monitors and reports the relative humidity and ambient temperature in its immediate environment. It is designed for use in environmentally- sensitive areas, such as IT data centers.Periodically reporting its unique ID along with the data observed by the sensor, the R155 is designed for use in combination with all RF Code fixed and mobile readers. This single use, affordable sensor is mounted in an impact resistant polycarbonate enclosure with strong adhesive on the back of the case. The sensor has an accuracy of +/- 2°F and +/- 5% RH(typical).
