Humidity Sensor PICtail Demo Board

Part Number: PIC16F690DM-PCTLHS

Summary:

This board supports the capacitive humidity sensor application note AN1016. It measures the capacitance of a relative humidity sensor plugged into the board. The on-board microcontroller sends the measured and calculated relative humidity (RH) to a PC for display.

The board can also measure small capacitors in different ranges of values using a dual slope integration method. The View More
