EN - What and how does Thermoview contribute to growth optimisation
Question
- Can Thermoview monitor crop temperatures at different spots properly?
- What kind of iSii control can be accelerated?
Answer
- A Thermoview camera can spot certain surfaces, it can provide temperatures of several items, like leaves, flowers and fruits.
- The Crop Condensation Module in iSii can be accelerated in order to protect crops and its fruits against condensation.

LetsGrow link for integration and data transfer
Thermoview is always - and exclusively - connected to the LetsGrow internet platform.
For tracking measurements in charts and for reporting purposes. By combining data,
you gain access to other real-time greenhouse data, such as temperature, relative humidity and CO2.

A LetsGrow user account is required; you need a new account or an extension to your current account.
iSii to protect fruits from condensation
Opposite to other greenhouse sensors, Thermoview not connected to iSii,
but its data could be send to your iSii, via internet.

You can accelerate the iSii Crop Condensation Module to protect fruits from condensation.
VPD plant
An accurate plant temperature sensor - not identical to Thermoview - is needed if you want to control based on VPD plant.
Advantages of Thermoview
- temperature measurement of crop, its leafs, flowers and fruits with one sensor only
- overview of different spot temperatures and environment, after processing by LetsGrow
- avoid crop (fruit) condensation by control
- realize a more homogenous greenhouse climate
With the Hoogendoorn iSii Next Generation Computer, it is possible to directly control the Crop Condensation Module.
Request and check manual and support document for further information.
The Thermoview camera can observe:
- 6 single spot temperatures
- 3 single boxes:
- 1 minimum temperature
- 1 maximum temperature
- 1 average temperature

Picture 3: Combined data at LetsGrow platform
LetsGrow can send box average temperatures to the iSii computer, for monitoring (comparison) purposes only.
Uni switches are needed to get concerning values ready to monitor within iSii at overviews and graphs.
Open below mentioned window in your browser and put available uni switch group number in.

Thermoview infrared sensing
Thermoview makes temperature differences within one fixed rectangular surface clear.
Due to various emissivities of the different spotted items, their distinc distance to the thermoview camera
and the need for calibration on a regular base, its accuracy is small.
This makes the Thermoview camera not suitable for accurate plant temperature measurement.
