The new TDWLB pressure/temperature sensor is the industry’s first to be powered with a coin-cell battery, controlled with a smartphone app, and certified as Bluetooth Smart. The device uses a patent-pending design and proprietary digital circuitry for high-energy efficiency to provide an 18- to 24-month battery life and redundant sensing. Its smartphone app lets the user name each sensor one time securely, then program set-points/alarms for multiple sensors, monitor readings, and graph activity over time — all from a phone, tablet or computer.
