For each sensor characterized, a boost voltage and warmup time was specified. The sample and reports rates were varied to calculate
the estimated battery life. For example, a Banner QT50ULBQ6-75390 sensor set to a boost voltage of 15 volts, a warm-up time of 500
milliseconds, and a sample and report rate of 15 minutes, should have a battery life of 4.45 years.
All battery life calculations are approximations based on a strong radio signal. Weaker radio connections and missed packets will de-
crease the battery life.
