Outdoor Temperature, Humidity & Illuminance Sensor

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.

Choose the configuration

Temperature and humidity

Two measured variables through RS485 Modbus RTU.

Temperature, humidity and illuminance

Adds a 0–200,000 lux light channel in the same housing.

Connection

Bare-wire or quick-connector cable end. Cable length: 10 m.

  • The operating environment is limited to -40 to 75 °C, even though the temperature measurement range extends to 100 °C.
  • The light channel measures illuminance in lux. PAR measurements use a separate quantum sensor.

Where it fits

Greenhouse outdoor reference

Provide an outside temperature and humidity reference alongside the measurements inside the growing area.

Farm microclimate records

Connect the RS485 measurements to a logger or RTU for time-stamped local weather records.

Daylight monitoring

Select the illuminance version for a lux reading at the measurement point.

Questions about this equipment

Does every version include the light channel?

Choose the temperature/RH version or the temperature/RH/illuminance version. The light channel belongs to the three-variable configuration.

How does it connect to a monitoring system?

It provides RS485 Modbus RTU readings and uses a 9–30 VDC supply. The connecting logger, RTU or gateway reads the selected channels.

Is the light reading PAR?

The light reading is illuminance in lux. A PAR quantum sensor provides the separate measurement used for photosynthetic photon flux density.
