Physically configure the Hawk and camera
- Install the Agtech1 card.
- Install the latest main board FW (v1.3 or later) via OEM Device Manager.
- Install the latest Agtech1 I/O card FW (v1.8 or later) via OEM Device Manager.
- Navigate to device details and change the card FW to v1.8 or later.
- Navigate to device details and change the card FW to v1.8 or later.
- Install the camera wires to the appropriate I/Os as illustrated below:
Note: As with the Eagle, for low noise performance this sensor requires a 100nF and a 10uF decoupling capacitor to be added to the sensor pins. See this Eagle Article for details. Without these capacitors, noise of ±2°C is expected.
Configure Systems Parameters in Device Manager
- Navigate to the Agtech1 tab and configure the parameters shown below.
- Navigate to the I2C Action 1 tab, and configure the following parameters in yellow:
- Sensor Type: The I2C sensor of choice. In our case, the MLX90640 Thermal Camera
- Sensor Parameter 1: Wakeup time (s) before performing a reading. Optimal time for accuracy is 4min (240s) – this is the value you used in a previous Eagle deployment.
- Sensor Parameter 2: Lens exposure (s). Value can be 0, 1, or 2. [0, 1, 2] => [2s, 1s, 0.5s]
- Sensor Parameter 3: Emissivity of the target (for calibration). Ranges from 0-1000. E.g. previous Eagle value was 0.98, the Hawk equivalent value is 980.
- Navigate to the Task 1 tab, and configure the following parameters in yellow:
- Period Unit: Units of the period you want Task 1 to run (e.g. seconds, minutes, hours). Eagle Parameter was minutes.
- Schedule period: Period between tasks.
- Log Multiplier (L): Log a task record every (L) times the task occurs.
- GPS Multiplier (G) Get a GPS fix every (G) time the tasked is logged. Occurs every (GxL) tasks.
- Upload Multiplier (U): Upload every U times the task occurs. Occurs every (L x U) tasks.
- Action 1: Select which action should be run for this task. In this case, we want to pick the I2C Action 1 option which we configured previously.
- Hit the update button to save the settings. The Hawk should now be configured to work with the MLX90640.
