This is mostly useful for my future reference. It contains the pin layout of the cables that connect to the outside of the project box.
The wind / rain sensors came with two separate RJ11 terminated cables. I combined the two cables into a single RJ45 connector to allow using the RJ45 waterproof cable glands.
| Pin | Description |
|---|---|
| 1 | Ground |
| 2 | Wind speed signal - to BCM GPIO pin #18 |
| 3 | +5V |
| 4 | Wind direction - to analog channel 0 on ADC |
| 5 | Unused |
| 6 | Unused |
| 7 | Rain gauge signal - to BCM GPIO pin #27 |
| 8 | +5V |
| Pin | Description |
|---|---|
| 1 | DHT Temperature / Humidity Signal |
| 2 | Unused |
| 3 | DHT Temperature / Humidity +3.3V |
| 4 | DHT Temperature / Humidity Ground |
| 5 | BMP180 I2C SCL |
| 6 | BMP180 I2C SDA |
| 7 | BMP180 +3.3V |
| 8 | BMP180 Ground |
