Soil, water and microclimate measurements
Depending on the project objectives, monitoring can include soil moisture and temperature, electrical conductivity (EC), pH, ambient temperature and relative humidity. Greenhouse applications may also include CO₂, light or PAR, leaf wetness and tank level. Sensor type is selected according to soil structure, expected measurement range, maintenance frequency and calibration requirements.
Protection for analogue probes must account for cable length, grounding and lightning-induced surges. For digital sensors, bus topology, addressing and field connectors matter. By controlling sensor power, the measurement board can reduce energy consumption and isolate a faulty probe from the other channels.
