Priva updates sensor/control software integration

Wireless sensors have proven to be a useful addition to regular measurements in the greenhouse. They can be easily moved within a compartment to give growers better insight into climate differences and help detect any anomalies.

The wireless sensors from Priva|Aranet can now be fully integrated with the control software of Priva Connext and Compact CC climate computers. This makes it possible to use multiple measurements in one strategy and control based on minimum, maximum or average measurement values.

Examples of applications for wireless sensors include measuring temperature and relative humidity, PAR and moisture levels.

Temperature and relative humidity (RH)

Today, growing crops means pushing control to the limits of what is possible. When temperatures are low and humidity is relatively high, this can lead to condensation on the plant as the temperature drops close to the dew point. This is especially common with plants growing close to the side walls. With one sensor per compartment you can only respond to that specific sensor. For example, with additional wireless sensors, the computer can respond to the lowest sensor value in any known cold spot and take the necessary action.


An indoor PAR sensor for measuring photosynthetically active radiation will always be in the shade during the day due to greenhouse construction or installations. Adding more PAR sensors will not reduce shading, but by using multiple sensors in a compartment it is possible to control your display based on the highest reading of the connected sensors (assuming not all PAR sensors sensors are in the shade at the same time). Another option is to compare the PAR measurement below and above the curtain.

Moisture content

With potted plants, the moisture content of the substrate in the pot can vary depending on where the plants are placed, whether they are on a bench or on the ground. By measuring the moisture in different places, you can adjust the watering to the driest value. This is also possible for determining the moisture content in bed crops and crops on different types of substrate.
