1-wire barometer

1-wire barometer

Based around the Motorola MPX4115A absolute pressure sensor.
This pcb also includes a service header (J1) for calibration purposes, all you have to do is plug the calibration tool onto this header and you can then inject the minimum and maximum voltages that you would expect from the pressure sensor output, this minimises the onboard component requirement and speeds up the calibration process. This pcb can be used for either the version 2 or 3 bray designs by just changing a few resistor values.
