| 9 | Notes for oregon_12s.sr | |
| 10 | ----------------------- | |
| 11 | ||
| 12 | This is a 12 second capture of 433 MHz amplitude modulated data. It contains | |
| 13 | traces for an Oregon Scientific THGN800 temperature and humidity sensor, a | |
| 14 | PCR800 rain sensor, a WGR800 wind sensor and a virtual BTHR968 temperature | |
| 15 | humidity and pressure sensor. There may also be some other signals in there | |
| 16 | too. | |
| 17 | ||
| 18 | In order to decode the Oregon v2.1 BTHR968 you will need to change the | |
| 19 | preamble to '1010 ...' in the ook decoder. Currently you can ook decode either | |
| 20 | a preamble of '1111 ...' or '1010 ...' but not both at the same time, so you | |
| 21 | can see Oregon v2.1 or v1/3 sensors. | |
| 22 | ||
| 23 | The signal was received by an RF Solutions RX12 superhet decoder chip and then | |
| 24 | passed to the logic analyser. | |
| 25 | ||
| 26 | The individual traces are also in separate files under the oregon folder. | |

| 32 | Logic analyzer setup | |
| 33 | -------------------- | |
| 34 | ||
| 35 | The logic analyzer used was a USBee AX Pro / Saleae Logic clone (at 25kHz): | |

| 44 | ---- | |
| 45 | ||
| 46 | * oregon_12s.sr: | |
| 47 | Contains a set of pulses that include Oregon Scientific PCR800, THGN800, | |
| 48 | WGR800 and BTHR968 sensors. | |
| 49 | ||
| 50 | * one_transition_10s.sr: | |
| 51 | Contains a single transition around 1 sec that is a useful template for | |
| 52 | using the ook_gen decoder. |
