Measure where it really happens
The iQblue Clara is an all-in one crop and field sensor that provides ultra-local data about plant and weather related parameters. With 7 sensors and 8 crop affecting parameters the iQblue Clara is a valuable decision making aid.
The benefit of crop climate measurements
The differences between ultra-local and non-field measurements.
As we all know diseases arise and develop in the micro-climate between the plants. There is a significant difference between crop climate and the regional or even local weather stations. That’s why the iQblue Clara has a smart positioned crop climate sensor. To provide you with the most reliable crop information.
Temperature variations are caused, among other things, by solar radiation, evapotranspiration and field-specific conditions, such as crop coverage and soil moisture status. These parameters have a major influence on temperature measurements. As can be seen in the graph above, the differences in temperature between crop, field and non-field measurements are substantial, up to 5°C. That is why iQblue Clara measures crop climate. The crop temperature measurement is important because it has a major effect on crop growth and disease and pest development.
Relative humidity variations are caused, among other things, by temperature, dew point, wind and crop-specific conditions, such as leaf wetness and evaporation. These parameters have a major influence on relative humidity. The graph above shows the significant differences between relative humidity in the crop, field and non-field.The differences through time are caused by the leaves remaining wet for much longer. This makes the measurement in the crop very valuable for a reliable disease pressure calculation.
Why measure soil temperature?
Soil temperature vs. nitrogen
Nitrogen occurs in the soil in 3 different forms: as organic matter, as ammonium and as nitrate, of which the ratio is managed by soil microbes. As soil temperature stimulates microbial growth, it gives insight into the available nitrogen in the soil. The uptake of nitrogen is important for plants to grow. At low temperatures, plants prefer ammonium while at high temperatures they prefer nitrate. Therefore, soil temperature also determines the choice of fertiliser during the season.

*Battery lifetime depens on mode, location, operation temperature and frequency of measurements and transmissions. Standard configuration givese a liftetime of 4-5 years (estimated based on test and simulations)
Simple, intelligent and ready to go.
Just dig a 40cm hole. The iQblue Clara should be positioned vertically to ensure reliable preciptation measurements.
Don’t place the iQblue Clara under trees or near buildings.
iQblue Clara has a motion sensor that detects its position:
• Vertical active mode
• 15% angle error mode
• Horizontal sleep mode
You can also read the mode at the SmartFarm app in the settings tab.
Accurate precipitation measurements require that the rain gauge be maintained regularly to avoid soiling. To do this, the rain gauge funnel, that is it’s upper part, must be opened and cleaned.
Frequently asked questions
To help you get started
One iQblue Clara can give enough information about one crop in an area of 3-5km.
- If not downloaded yet, download the SmartFarm app in the Apple App store or Google Play Store.
- Create an account within the SmartFarm app
- Install the iQblue Clara in your field*
- Add the iQblue Clara to your account by tapping the “+” button at the top of the screen and follow the instructions
Note, it can take up to 24 hours before the iQblue Clara start transmitting data to the SmartFarm app
* Installation tips
– Find a representative location in the crop
– Not beneath trees or close to buildings
– Not close to the road to prevent theft
– Within 3 meter of a spray track to avoid damage of sweeping sprayingbooms
– Drill/dig a 40cm deep hole and place the iQblue Clara.
– Fill the hole with loose soil and ensure the iQblue Clara is placed upright.
Your iQblue Clara is probably leaning more than 15°, place your iQblue Clara upright to do correct measurements.
Your iQblue Clara is probably lying horizontaly or is placed upside down.
In these positions iQblue Clara is in sleep mode and only sends one message a day, to save energy.
Yes, and it’s very easy.
Just pull the iQblue Clara out of the soil and move it to it’s new location and keep the installation tips in mind.
After placement go to the SmartFarm app and adjust the iQblue Clara’s location at the settings menu.
When you’ve also put the iQblue Clara in another crop, please adjust the crop as well.
The rain gauge needs some maintenance from time to time.
Pull off the upper part of the rain gauge and clean the spoon and bucket.
Make sure the wires inside the bucket are not obstructing the spoon.
