Digi Smart Differential Pressure Sensor

Differential Pressure and Temperature Monitoring

The Digi Smart Differential Pressure Sensor is a battery operated differential pressure and temperature sensor with a microprocessor controlled IEEE 802.11b/g radio transceiver. The sensor has an onboard clock that allows it to spend most of the time in a low power quiescent state. Onboard calibration tables provide a linear temperature output. This information is combined with a CRC-16 error check and transmitted in a very short data packet that results in a very short transmitter on-time. This architecture allows the Digi Smart Differential Pressure Sensor to consumer very low energy.
