Frequently asked question (FAQ)
🌤️ Relative air humidity (percentage of moisture in relation to the maximum moisture percentage of the air for this temperature)
🌡️ Air temperature
🌱soil temperature at -10cm, (FS21 has an additional sensor at -20cm) and soil moisture at depth -10cm, -20cm and -30cm.
Relative Humidity Accuracy @25°C (20%RH to 80%RH): ±2 %RH
Accuracy temperature soil and air: ±1°C or better.
Soil moisture: this depends on how the sensor is placed and whether the right soil type is selected. In general a soil moisture accuracy of +/-3% can be achieved when the required installation procedure is followed.
We often get asked this, but the answer is not straightforward. It really depends on the crop type, the consistency of your field and your data accuracy requirements.
Usually we advise an average of 1 sensor per 1.5ha, as a very general recommendation. Contact us and one of our partnership managers will make sure you have the perfect amount of sensors for your needs.
For the FS21: You can find an instruction video here or have a look at the FS21 installation guide.

No, this sensor is designed to be visible above the soil. However – the robust hardware means that you can spray, irrigate and treat crops with the sensors in place.
Each sensor has a depth indication line that tells you how far to place the sensor in the soil.
Yes. Our FS21 sensors have a GPS tracker, but during the installation process the system stores your smartphone’s current location as the sensor location as well. In the platform the location of the sensor can be easily adjusted when incorrect or when the sensor is moved to another spot.
The answer to this question is twofold; after heavy rain the air surrounding the humidity sensor still contains moisture, it takes some time to diffuse. The other factor lies in the wet soil moisture, water evaporating from the moisture creates a high humidity zone close to the soil.
For the FS21: Rechargeable 5500mah battery (can be charged over USB-C)
For the FS11: a standard 3.0V CR123A battery (also known under the following names: CR123, 17345 and 16340).
Depending on weather conditions, antenna distance and type of connectivity (NB-IoT and LTE-M are best) the battery should last up to one year on a single charge.
All data is transmitted encrypted.
As soon as a battery is placed inside the Farm21 soil sensor, it will attempt to connect with the network. Once a secure data connection is obtained, the sensor will transmit data according to the set interval. If the sensor is outside reach for the network, data will not show up in the data platform.
If problems continue, refer to the help center for assistance..
At this point in time only Farm21 sensors can be added to the dashboard. Feel free to leave a feature request if you think this should be possible.
Automatically redirecting the data for the Farm21 sensor is possible on request. Feel free to contact us.
Yes, all data can be exported to common formats.
No limit on the maximum number of sensors! Farm21’s platform scales with you and your business.
We offer connectivity 140+ countries accross the globe. Including Europe, USA, Canada, most of South America, Russia, most of Asia, Australia, and some countries in Africa.
You can deactivate a sensor by navigating to the Sensors page on the Farm21 platform:
Step 1: Click on ‘edit’ of the sensor you want to delete
Step 2: On the bottom, you select ‘Unlock sensor from the field and deactivate sensor’
Your license starts the moment you have linked your sensor to your account. The subscription is on a yearly basis and is renewed automatically if you don’t deactivate your sensor. When you have linked your sensors on different days, the subscriptions will not be charged at the same moment. You can find an overview of all your licences on the My account page > Payments > Licences.
