Devices Supported: MCP6291, PIC16F690

Summary Description:

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

Supported Operating Systems:

• Windows 98 SE®
• Windows Me
• Windows 2000
• Windows XP

Other Requirements:

• 4 MB available on PC’s hard drive
• Available USB port

Companion Tool:

• PICkit™ 1 Flash Starter Kit
