ENVICO Humidity Adapter

Top side, MC9808, ±0.25°C

Bottom side, CC2D35, ±2%RH, (±0.3°C)





✈ Circuit Description




This board allows a lot of different assembly options. You mayst want to measure tempereature with a TMP101, an MCP9808 or with an CC2D35. The humidity is measured with a CC2D35, located on the bottom side of the pcb. The unpopulated SO8 is for an eeprom to hold sensor name and calibration data as well as alarm and warning levels (professional version). In order to be independant of the supply voltage, an MCP1703 5 V regulator (SO-23) has been added as well.
