Wireless sensors integration with climate computer control software

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.

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

Wireless sensors can be used for numerous things in and around the greenhouse.

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 the floor. By measuring the moisture in different places, you can adjust the irrigation to the 'driest' reading. This is also possible for determining the moisture content in bed crops and crops on different substrate types.

Temperature & relative humidity (RH)
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.
