Low cost infrasound monitor using i2c digital differential pressure sensor Described is a well established opensource geophysics project to monitor atmospheric infrasound 24/7. It employs a modern digital, I2C enabled diferential pressure sensor - unlike the older analog devices typically used. The system automatically uploads plots whilst data is stored in standard .mseed for further analysis. Very open-ended with lots of opportunities for students of all levels, schools and above, to redesign and test replacement components. This is real science, in a little studied area. The equipment required is relatively cheap to build and offers many opportunities for students of all ages to build and refine a sensing system of research quality.
The design and software is released open-source.
