Ambient humidity meter.
- 5V - Consumes 2mA
This Tibbit is based on the HIH6130 ambient humidity and temperature sensor IC with I2C interface. The sensor is implemented as the C1 device with perforated front face and a rubber wall separating the sensor from the internal space of the TPS system. This is done to minimize the influence of the heat produced by the TPS motherboard and adjacent Tibbits.
The module measures the ambient relative humidity with 0.04% resolution and +/-4%RH accuracy. The temperature is measured with 0.025 deg.C resolution and +/-1 deg.C accuracy.
This C1 device requires the Tibbit #00-3 to be installed in the neighboring "M" Tibbit socket. #00-3 provides two direct lines for I2C comms, as well as the ground and +5V power for the HIH6130 IC.
The use of this Tibbit is illustrated by a Tibbo BASIC test project. Yo can find it here: https://github.com/tibbotech/CA-Test-Tibbit-30.
