The SB-100 combines excellent performance in a small package size at an affordable price. The sensor works well as a stand-alone product or to combine it with sensors affected by barometric pressure, such as our line of oxygen sensors. Typical applications include pressure measurement in weather networks, often for weather forecasting and to correct the output of sensors that are sensitive to pressure changes (for example, Apogee oxygen sensors).
