CS106 Barometric Pressure Sensor

1. General

The CS106 analog barometer uses Vaisala’s Barocap® silicon capacitive

pressure sensor. The Barocap sensor has been designed for accurate and stable

measurement of barometric pressure. The CS106 outputs a linear 0 to

2.5 VDC signal that corresponds to 500 to 1100 mb. It can be operated in a

shutdown or normal mode. In the shutdown mode the datalogger switches

12 VDC power to the barometer during the measurement. The datalogger then

powers down the barometer between measurements to conserve power.
