Low cost microbarometer station, 1Pa resolution. This project complements our infrasound monitor. A microbarometer with approx 1Pa resolution and 0.4Pa noise threshold based on the digital ICP-10125 i2c enabled absolute pressure sensor.
The sensor is interfaced with a Raspberry Pi providing signal processing, saving data in .mseed format, plotting and then uploading plots to a server. System has performance of research/professional systems at a fraction of the price. A full rig, premounted sensor and a Raspberry Pi costing approx £70.
