The BAPI-Stat "Quantum" Wireless Room Temperature and Humidity Sensor (BA/WTH-BLE-Q-SO-BAT) measures both temperature and relative humidity and transmits via Bluetooth Low Energy to the BAPI BLE Receiver or Gateway. Battery (2x BA/LI14505 3.6V lithium AA). Optional setpoint slider for wireless occupant setpoint adjustment. Optional override button transmits occupied signal.
Best for: Wireless room temperature and humidity sensing for HVAC BAS applications. Each measured variable (temperature and humidity) requires a separate analog output module when using the receiver-based system.
5-Year Warranty
Backed by BAPI's 5-year warranty. Up to 16,000 readings stored onboard in gateway mode. At 10 min/5 min intervals, estimated battery life is 8.93 years.

Frequently Asked Questions
How many output modules does a temp/humidity sensor require?
Two — one for temperature and one for humidity — when using the analog receiver-based system. Each variable requires its own output module (ROM/VOM for temp, VOM for humidity).
Can this sensor work with both the receiver and gateway?
Yes but not simultaneously. Pair to the receiver for analog/digital output module integration, or to the gateway for WAM cloud monitoring.
What batteries does this sensor require?
Two 3.6V lithium AA batteries (BA/LI14505). Standard 1.5V AA batteries are not compatible.
