MCP6291 and PIC16F690 Humidity Sensor PICtail™ Demo Board

PIC16F690DM-PCTLHS Humidity Sensor PICtail™ Demo Board using the MCP6291 and PIC16F690

Microchip Technology

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.

Features
  • Simple interface to a PC using the PICkit™ 1 Flash Starter Kit
    • GUI program displays capacitance and Relative Humidity results
    • Can program the on-board PIC16F690
    • Sockets for inserting radial leaded capacitors
  • User selected capacitance range
  • Test points to monitor circuit’s operation
  • ICSP™ connection gives alternative for programming the on-board PIC16F690:
    • PICkit™ 2 Microcontroller Programmer
    • MPLAB® ICD 2
