The Barometer measures atmospheric pressure, and can be used on its own or as a part of your total weather monitoring system. This barometer is based on a design by Tim Bitson. It reads pressure from 28-32 inHg (948-1083 mb). It's resolution is approximately 0.01 inHg (0.34 mb). Since indoor and outdoor pressure are typically close to the same, we recommend installing this board indoors to avoid possible sensitivity to moisture in an outdoor setting.
This is a fully assembled and tested unit. This device comes with dual RJ45 connectors, as well as screw terminals, for easy connection to your 1-wire network, and requires power of 15-24 volts DC. Either our Power Injector or our 6 Channel Hub would provide the needed power.
