5 This is an example capture of a virtual Oregon Scientific BTHR968 temperature,
6 humidity and pressure sensor which transmits at 433.92 MHz using Manchester
7 encoding and amplitude modulation.
9 The signal was received by an RF Solutions RX12 superhet decoder chip and then
10 passed to the logic analyser.
12 In order to decode the Oregon v2.1 BTHR968 you will need to change the
13 preamble to '1010 ...' in the ook decoder. Currently you can ook decode either
14 a preamble of '1111 ...' or '1010 ...' but not both at the same time, so you
15 can see Oregon v2.1 or v3 sensors.

25 The logic analyzer used was a USBee AX Pro / Saleae Logic clone (at 25kHz):
30 1 Output from Arduino running virtual BTHR968
37 Contains a single set of pulses that belong to a virtual Oregon Scientific
38 BTHR968 temperature, humidity and pressure sensor. These should decode as
39 channel 2, battery OK, rollingcode BC, temp 11.2 deg C, humidity 52%,
40 pressure 1013mb, checksum OK.
