TEMPERATURE AND RELATIVE HUMIDITY SENSOR

This Temperature and Relative Humidity Sensor measures humidity and environmental temperature with great precision.

Unlike the self-ventilated model, this model does not recirculate the air inside.

For healthy crops, it is very important that the environmental humidity does not reach extreme values. Very high humidity favors pest and disease transmission, while low humidity can stress the plant.

Temperature and environmental humidity control is also vital for plant health. Ensure that the value is between certain values that vary according to the cycle the crop is in. To control it, heaters can optionally be installed, ventilating by opening windows or fans…

Connecting this temperature and relative humidity sensor with a Climate Controller controls the air temperature and humidity in a greenhouse, farm, cellar or dryer.

CONNECTING THE TEMPERATURE AND RELATIVE HUMIDITY SENSOR

Contact 1 – (V+) 15-30 Vdc probe power.

Contact 2 – (HR) Output signal to the Relative Humidity controller

Contact 3 – (Tª) Output signal to the Temperature controller
