The Priva|Aranet wireless sensors can now be fully integrated with the control software of Priva Connext and Compact CC climate computers. This will make it possible to use multiple measurements in a single strategy and control based on minimum, maximum, or average readings.

Wireless sensors have proved to be a useful addition to regular measurements in the greenhouse. They can easily be moved within a compartment to give you better insights into climate differences and to help you track down any deviations. The Priva|Aranet wireless sensors can now be fully integrated with the control software of Priva Connext and Compact CC climate computers. This will make it possible to use multiple measurements in a single strategy and control based on minimum, maximum, or average readings.

Examples of applications for wireless sensors include measuring temperature & RH, PAR, and moisture levels.

Temperature & relative humidity (RH)
Nowadays, growing crops means pushing control towards the boundaries 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 particularly common in plants growing near the side walls. With one sensor per compartment you can only respond to that particular sensor. With additional wireless sensors, e.g., in every known cold spot, the computer can react to the lowest sensor reading and start the required action.

PAR
An inside PAR sensor for measuring photosynthetic active radiation will always encounter shade during the day due to greenhouse construction or installations. When you add more PAR sensors it will not reduce the shade, but by using multiple sensors in a compartment it is possible to control your screen based on the highest measured value of the connected sensors. (assuming that all PAR sensors are not in the shade at the same time.) Another option is to compare the PAR measurement below and above the curtain.

Moisture content
With pot plants, the moisture content of the substrate in the pot can vary depending on where the plants are located, regardless of whether they are placed on a bench or on the floor. By measuring the moisture in different places, you are able to adjust the irrigation to the ‘driest' reading. This is of course also possible for determining the moisture content in bed crops and crops on different types of substrate.

Marcel van der Voort, co-owner of pot lily and pot chrysanthemum nursery Van Schie, grows under full LED: "The wireless wireless sensors give me highly localized insights into crop responses to changes in climate and light conditions."

Flexible solution
Priva-Aranet sensors are not only easy to install but also flexible and scalable. Priva offers various starter kits that you can use to get started right away. Happy with your current kit but looking to use the sensors more widely in the future? Up to 100 sensors can be connected to one base station.
