Temperature and humidity
Two measured variables through RS485 Modbus RTU.
Air temperature · Relative humidity · Illuminance option
Read outdoor air conditions beside a greenhouse, crop area or microclimate station. The louvered shield reduces direct sunlight and ground-reflected heat on the sensing area. Choose temperature and humidity, or add illuminance in the same housing.

Two measured variables through RS485 Modbus RTU.
Adds a 0–200,000 lux light channel in the same housing.
Bare-wire or quick-connector cable end. Cable length: 10 m.

Provide an outside temperature and humidity reference alongside the measurements inside the growing area.
Connect the RS485 measurements to a logger or RTU for time-stamped local weather records.
Select the illuminance version for a lux reading at the measurement point.
Include these details with your inquiry so the equipment and options match your site.
Choose the temperature/RH version or the temperature/RH/illuminance version. The light channel belongs to the three-variable configuration.
It provides RS485 Modbus RTU readings and uses a 9–30 VDC supply. The connecting logger, RTU or gateway reads the selected channels.
The light reading is illuminance in lux. A PAR quantum sensor provides the separate measurement used for photosynthetic photon flux density.
