81 Pressure Module

The Pressure1 module is an easy to use pressure sensor module that increases the functionality of the 81 controller board. The module utilizes Honeywell’s SSC line of digital pressure sensors. The module plugs into either of the module ports on the 81 controller board. The Pressure1 module uses the I2C bus to communicate with the microcontroller on the 81 board. It has DIP switch to engage or disengage pull-up resistors for the I2C bus.
