How to get started with Franklin Lightning Sensor Demo Kit
Due to the sensitive nature of the sensor towards noise and disturbers a separate
application note is provided. It explains the operational environment and board placement
for which the demonstration will work as intended. This information is given in the
application note “AS3935_AppNote_AN03_DemoKit_Setup_EN_v1.pdf”.
Insert the 3V battery (CR2032) in the battery holder
“C”
on the AS3935 demo board.
Insert a 3V battery in the battery holder
“G”
on the Lightning Emulator.
Position the lightning emulator and the AS3935 demo board in such a way that both antennas
are in parallel to each other. Keep a distance of 10-15 cm between both boards.
Turn on the AS3935 Lightning Sensor via the ON/OFF
– switch
“A”
. When you switch on the
board you will see on the LCD the austriamicrosystems logo followed by the LCO and the RCO
calibration. After successful calibration the AS3935 goes into sense mode awaiting a lightning.
Note:
The LCO should be tuned to 500 kHz, the TRCO to 1.1 MHz and the SRCO to 32 kHz.
To manually execute the tuning procedures connect the USB plug before turning the demo
board on via switch
“A”
.
Turn on the Lightning Emulator via the ON/OFF
– switch
“F”
. When turned on, the blue LED
will be continuously flashing.
Note:
Make sure the battery of the Lightning Emulator is full. Otherwise lightning might not be
emulated correctly.
Now you can start to press the switches “Far Strike”, “Mid Strike” and “Close Strike” (button “
B
”,
“
C
”,
and
“
D
”)
on the Emulator, simulating lightning events that will be detected by the sensor.
The display will flash up showing the signs described above and the buzzer will trigger an
alarm.
If a disturber is emulated (button
“A”
) the AS
3935 demo board will show “Disturber detected”.
