An automated greenhouse climate system regulates irrigation and misting using a water pump (waterPump).

The system must turn the water pump 'ON' if either of the following safety conditions is met:

• The soil moisture level (soilMoisture) falls below its dynamic target threshold, which is defined as 0.3 * solarRad + 12 (where solarRad represents solar radiation in ${W/m}^2$).
• The ambient air temperature (airTemp) exceeds 35°C.

Otherwise, the water pump must be turned 'OFF'.
