Humidity Sensor PICtail™ Demo Board User's Guide
2.3.1
1. Remove any PICmicro microcontroller that may be in the Evaluation Socket.
2. Connect the USB cable to the PC and to the PICkit™ 1 Flash Starter Kit board.
The status LEDs (green POWER and yellow BUSY in the LED array) should light
up.
It is easiest to use this board when it lays directly on a bench top.
2.3.2
1. Setup Board (first time only); connect shunt to jumper JP1 at the 0.1 pF / position
(0.1 pF / count).
2. Plug this board into the PICkit 1 Flash Starter Kit's expansion header J3 (as
shown in Figure 2-1) without covering the LED array. There should be no change
in the status LEDs on the PICkit™ 1 Flash Starter Kit board after it is plugged in.
The PIC16F690 comes with the 00084R1.hex file already programmed.
2.3.3
1. Run the installer program, AN1016 install.exe (which places the executable
file capacitance.exe in the desired directory).
2. Run the capacitance.exe PC Program to start the Graphical User Interface
(GUI).
2.3.4
1. Check Basic Functionality.
a) Place one of the capacitors that came in the shipping box (nominal values of
b) Follow the steps 1.a. through 1.g. in Section 3.3 "Using the Humidity
c) The reading should be within ±5% (for 10 pF, 180 pF, and 1.0 nF capacitors),
2. Check HS1101LF Sensor.
a) Place the HS1101LF sensor into the Csen socket.
b) Follow the steps 2.a. through 2.f. in Section 3.3 "Using the Humidity
c) The reading should be similar to that of a calibrated relative humidity sensor
