#35, C1: Barometric Pressure Sensor
Function: Barometric pressure sensor
Form factor: C1
Special needs: Tibbit #00-3
Power requirements: 5V/2mA
Details
Tibbit #35 is based on the MPL115A2 barometric pressure measurement IC with an I²C interface. The sensor is implemented as a C1 device with a perforated front face.
The module measures the atmospheric pressure with 0.15kPa resolution and ±1kPa accuracy.
This C1 device requires Tibbit #00-3 to be installed in the neighboring "M" Tibbit socket. #00-3 provides two direct lines for I²C communications, as well as the ground and +5V power for the MPL115A2 IC.
Sample Project
The use of Tibbit #35 is illustrated by a Tibbo BASIC test project. You can find it here: https://github.com/tibbotech/CA-Test-Tibbit-35.
