Temperature and Humidity

DHT22 sensor

Is intended for measuring the air temperature and relative humidity With this sensor, you can measure the temperature and humidity inside the growing area. Based on the measured values you can effectively manage not just ventilation, but also the heating, humidification and dehumidification.

Resolution of 0,1°C a 0,1% RH. 

For most effective measurement place the sensor out of direct sunlight or heat from lamps, out of entrance to the growing area, approximately in half the height of plants. Realize, that in different parts of growing area is not the same temperature - ceiling height as well as distance from light affects accuracy of measurement.


As well as all other sensors, theese are connected to main unit using flat four-wire telephone cable with RJ-11 connectors. Tested cable length is 15m, standard supply is 5m.
