The tag is designed for years of reliable performance in an operating
range from –4°F to +158°F 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 R155’s 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.
