Firmware Requirements
The WNK81TP requires:
- Baseboard
- FW v1.8+
- Card
- Agtech1 FW v1.12+ or
- Bluetooth Card FW v1.2+
Wiring
Wire as below:
| WNK81TP | Agtech1 | Bluetooth+ |
| VCC (Red) | Hawk IO 5 | Hawk IO 7 |
| SCL (Yellow) |
Hawk IO 6 | Hawk IO 5 |
| SDA (White) | Hawk IO 4 | Hawk IO 6 |
| GND (Black) | Hawk GND | Hawk GND |
Device Manager Configuration
- Confirm you are on the correct Baseboard FW
- FW v1.8+
- Confirm you are on the correct Card FW
- For Agtech1 Card, FW v1.12+
- For BLE Card, FW v1.2+
- Add the I2C Action tab (see image below)
- Select the WNK81TP Pressure Temp Sensor option from the dropdown.
- I2C Address can be left at 0 to use the default address (which is 0xDA)
- Analog Offset can be set to the Analog you want to save the Pressure temperature to.
- The Temperature Value will be saved to the next one (i.e. Pressure in Analog 10, Temperature in Analog 11)
- Sensor Parameter 1: The Pressure mimimum.
- Sensor Parameter 2: The Pressure maximum.
- e.g. if the max value the sensor can read is 10 Bar, set to 10,000 and divide out on the server side to get 5 significant figures.
- Sensor Parameter 3: Can be left as 0 to use the default Temperature address which is (0xFE)
