Precision Pressure Meter Project
This video documents the design process behind a one-off prototype precision pressure meter. This device can measure pressure to one ten-thousandth of a PSI! Here I demonstrate the design process including reading the datasheet to figure out the I2C commands, using a Bus Pirate to practice exchanging data with the sensor, using a logic analyzer to sniff the I2C lines, using Python and a Bus Pirate to record and graph temperature and pressure data, and finally building it all into an enclosure controlled by an ATMega328 microcontroller.
