PIC16F690DM-PCTLHS Humidity Sensor PICtail Demo Board

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 board can be modified, if desired, to achieve better measurement resolution.

  • Simple interface to a PC using the PICkit™ 1 Flash Starter Kit
  • User selected capacitance range
  • Test points to monitor circuit’s operation
  • ICSP™ connection gives alternative for programming the on-board PIC16F690:
