R155 Humidity-Temperature Tag


RF Codes R155 Humidity-Temperature Tag 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 sensor data observed by the tag, the R155 is designed for use in combination with RF Code fixed and mobile readers. This affordable sensor tag is mounted in an impact resistant polycarbonate enclosure with strong adhesive on the back of the case. In temperature-controlled settings, such as offices and data centers, the sensor has an accuracy of +/-2F and +/-5% RH (typical).



The tag is designed for years of reliable performance in an operating range from 4F to +158F and 0% to 95% RH. The battery life for the Humidity-Temperature tag will exceed 3.5 years in most deployment environments. The tag operates with a very low duty cycle and a 10-second beacon rate. The R155s form factor ensures clear signal transmission in high-density deployments. Featuring a low-battery alert, the tag will continue to monitor humidity and temperature for at least three months following this alerting. After that, the tag will continue to broadcast its unique ID and a low battery indication with each beacon, but will not report temperature and humidity until the battery is replaced.

Note: Humidity sensors are not designed for use in harsh chemical environments; prolonged exposure to chemical vapors in high concentrations may diminish the accuracy of the sensor readings.
