You’ve received your Sensoterra sensors and are ready to start measuring soil moisture data. That’s great! Before you begin, we’d like to point out some tips for installing and caring for your Sensoterra sensors. Feel free to download the Single Depth installation guides for easy access.
1.1 How do I create a customer account?
Please download the Sensoterra app from the Apple App Store (iOS) or Google Play Store (Android) and follow the steps in the app to register yourself. You'll need to install the app and register an account before installing hardware in the field.
1.2 Do I need extra tools in the field?
If a LoRa network is present, no extra tools are needed. If private LoRa gateways are necessary, some basic additional tools may be needed to mount the gateway indoor or outdoor.
If you have a gateway and need help installing it - watch our quick and handy installation guide on our YouTube channel.
1.3 When will I first receive the data?
The first data will be received and is viewable online within 5 minutes after shaking and inserting a probe in the soil.
2.1 What does the probe measure?
Volumetric soil moisture content.
2.2 How do I turn on the probe?
You don’t need to turn on a probe, it is already active.
2.3 Do I need to calibrate the probe?
No, Sensoterra provides default calibrations curves for sandy, clay and peat soils to convert the raw data to soil moisture percentages. These can be selected via the app or customer website. A custom calibration is available, please contact customer support.
2.4 What is the range of the probe?
The guaranteed range from probe to gateway is 1.5 km line of sight. Please be aware that obstacles between probe and gateway may decrease the range.
2.5 How high should the probe extend above the soil?
Push the probe down in the soil till the blue part of the probe sticks out above the soil 3-5 inches or 7-15 cm.
2.6 Can I install the probe by hammering?
The probe is designed to withstand gentle hammering with a rubber mallet, however, the user assumes any risk of breakage associated with hammering. Watch how to install a probe.
2.7 How do I connect a probe to a gateway?
If a LoRa network is present, the Sensoterra probe will automatically connect to the nearest gateway after you have configured the probe in the app.
2.8 How to configure a probe?
Use the ‘Sensoterra app’, login and follow the instructions 'adding a probe'.
2.9 Does a probe measure soil moisture during the night?
Yes, the probe sends hourly data.
2.10 Can I set thresholds to alert me when soil moisture gets below or higher than a certain value?
Yes, you can configure the threshold for each probe in the app, and change this value over time, depending on crop development.
2.11 What frequency is used to transmit data from the probe to the gateway?
In Europe and Asia the probe communicates at 868 MHz, in North America and Mexico the probe communicates at 915 MHz.
2.12 The soil moisture reading for one of my probes is 0%.
Please check if there are any cracks in the soil which might prevent the probe tips to make proper soil contact.
2.13 The soil moisture readings seem very high.
Confirm the proper soil type has been selected, and/or consider selecting a different soil type calibration (eg clay instead of sand). High salinity may affect soil moisture readings.
3.1 What platforms are supported?
The app is distributed on iOS and Android.
3.2 I have trouble logging into my customer account.
Please check if you have an active internet connection and if you have the latest update of the App. If the problem persists please contact customer support.
3.3 How do I move a probe to a different location?
Just relocate the probe and re-register it with the app. The app and site will show the probe on the new location.
3.4 How can I delete a probe from my account?
You cannot delete a probe from your account, but you can disable the probe by editing the probe in the app and changing the status from “Operational” to “Disabled.”
3.5 Can I view my probes and graphs on my PC or laptop?
Please go to https://monitor.sensoterra.com and log in with your credentials.
3.6 One or more probes have been flagged either yellow or red in the app.
This indicates either a) the soil moisture is below or above the preset thresholds, or b) the probe has not uploaded data at least 24 hours.
4.1 Where can I view my soil moisture data?
Through the Sensoterra app on your smartphone, or the customer web portal: http://monitor.sensoterra.com.
4.2 What soil types are supported?
The soil moisture probe can be used for any type of soil, and is factory calibrated for sandy, clay and peat soils. The probe can also be used in soilless substrates, like perlite. For custom calibrations contact customer support.
4.3 In what unit is soil moisture measured?
The soil moisture is measured as volumetric water content percentage.
4.4 Is it possible to download the soil moisture data?
Yes, you can download all soil moisture data through the customer web portal.
4.5 Is it possible to export the soil moisture data to other software systems?
Sensoterra has an open API. For more detailed information, please reach out to our customer support.
