BARO-1 barometer module
The Indigo520 transmitter is available with a BARO-1 module. The BARO-1 barometer module
uses a BAROCAPâ silicone capacitative absolute pressure sensor developed by Vaisala for
barometric pressure measurement applications. The sensor has excellent hysteresis and
repeatability characteristics, low temperature dependence, and very good long-term stability.
