The T9602 is an IP67 rated Temperature + Humidity Sensor which can be used with the Hawk for temp+hum monitoring applications
3rd Party Sensor
The T9602 is a 3rd Party sensor - the advice given below is general. Always check the product datasheet direct from the manufacturer. Specific guidance on installation and usage should be obtained directly from the manufacturer. The instructions below are based on a sensor tested at the time of article writing - things may change.
Selecting Sensor
There are many T9602 variants. Ensure to select one which operates on 3V3, and not 5V
IO Card
Ensure a plug-in IO card with an I²C interface is fitted to the Hawk. Currently the only card with this interface is the AgTech1 card.
Wiring
| T9602 | Agtech1 | Bluetooth+ |
| 3V3 | Hawk IO 5 | Hawk IO 7 |
| SCL | Hawk IO 6 | Hawk IO 5 |
| SDA | Hawk IO 4 | Hawk IO 6 |
| GND | Hawk GND | Hawk GND |
Parameters
I²C Action Parameters
- Select T9602 as the Sensor Type
- Choose an Analogue to write the values to.
- Temp will be written to analogue offset
- Hum to analogue offset + 1
- In the example below this would be Temp in Analogue 15, and Humidity in Analogue 16
The I²C address can be left blank. For reference address 80 (0x50) is polled when taking a reading.
Task Parameters
Ensure the I²C action you have configured above (Action 1 or 2) is set as an action of the task.
Output/Conversion
With the above parameters, the output would be:
| Value | Analogue | Units | Conversion Example |
| Temperature | Analogue Offset Value | °C * 100 | 800 = 8°C |
| Humidity | Analogue Offset Value + 1 | % * 100 | 5000 = 50% |
