#30, C1: Ambient Humidity/Temperature Meter
Function: Ambient humidity and temperature meter
Form factor: C1
Special needs: Tibbit #00-3
Power requirements: 5V/2mA
Details
This Tibbit is based on the HIH6130 ambient humidity and temperature sensor IC with an I²C interface. The sensor is implemented as a C1 device with a perforated front face and a rubber wall separating the sensor from the internal space of the host Tibbo Project System (TPS). This is done to minimize the influence of the heat produced by the Tibbo Project PCB (TPP) 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°C resolution and ±1°C accuracy.
This C1 device requires Tibbit #00-3 to be installed in the neighboring "M" Tibbit socket. Tibbit #00-3 provides two direct lines for I²C communications, as well as the ground and +5V power for the HIH6130 IC.
Sample Project
The use of Tibbit #30 is illustrated by a Tibbo BASIC test project. You can find it here: https://github.com/tibbotech/CA-Test-Tibbit-30.
