Irrigator Pump Threshold

The GreenSense irrigator automatically turns on the pump when the soil moisture reading drops below the specified threshold.

The threshold chosen depends on the type of plant and how much water it needs.

Set the Pump Threshold

Linear MQTT Dashboard

The Linear MQTT Dashboard user interface can be used to set the pump threshold from a mobile device.

Open the Linear MQTT Dashboard:

Select the tab corresponding with the target GreenSense device (eg. Irrigator1):

Use the slider under the "Threshold" label to adjust the threshold.

The pump should detect the change and the the user interface should reflect the new option.

Note: There may be a delay between selecting a new pump status and having it detected by the device then refected on the user interface.

Examples:

Now you can choose the minimum soil moisture percentage. The pump will be turned on if soil moisture levels falls below the specified threshold, and continue to pump (in bursts) until it is above the threshold again.

Test the Automatic Irrigation

To check that the automatic irrigation works, set the threshold to 100:

Because the soil moisture reading is below the threshold, the pump will turn on automatically (for short bursts).

After testing, set the threshold back to the desired value.
