5 This is an example capture of an Oregon Scientific PCR800 rain sensor which
6 transmits at 433.92 MHz using Manchester encoding and amplitude modulation.
8 The signal was received by an RF Solutions RX12 superhet decoder chip and then
9 passed to the logic analyser.
11 In order to decode the Oregon v3 PCR800 you will need a preamble of '1111 ...'
12 (default) in the ook decoder. Currently you can ook decode either a preamble
13 of '1111 ...' or '1010 ...' but not both at the same time, so you can see
14 Oregon v2.1 or v1/3 sensors.

24 The logic analyzer used was a USBee AX Pro / Saleae Logic clone (at 25kHz):
29 1 Output from Arduino running virtual BTHR968
36 Contains a single set of pulses that belong to an Oregon Scientific PCR800
37 rain sensor. These should decode as channel 0, battery OK, rainfall 0
38 in/hour, total 38.885 inches (since the battery was changed), checksum OK.
