Ground-truth data to match the satellite view
AgriSense reads your fields from space. The Soil Scanner adds what satellites cannot see: the moisture, acidity, salinity and nutrients in the root zone, measured where you place the sensor.
Readings arrive in the same AgriSense portal as your crop health maps. Each reading gets a soil health score, plain-language advice and an alert when something needs attention.
- 7 readingsSoil moisture, soil temperature, pH, salinity (EC), nitrogen, phosphorus and potassium.
- 3 ways to connectWi-Fi nodes, long-range LoRaWAN nodes and a handheld Bluetooth probe.
- AlertsDry soil, waterlogging, acid or alkaline soil, salinity, low nutrients and low battery.
- PhotosAttach field, soil or drone photos with GPS to any device from the phone app.

Move the sliders, or pick a sample soil. This demo uses the same scoring rules as the AgriSense soil service. The values are examples, not measurements from a real farm.

What to do
Best-fit crops for these readings
Guidance only. Confirm fertiliser, lime and gypsum decisions with a lab soil test and an agronomist.
The hardware
We supply, install and calibrate the kit, or you can build it from our open firmware and parts list.
Field node (Wi-Fi)
A solar or battery ESP32 unit that wakes every 15 minutes, reads, sends and sleeps.
- 7-in-1 soil probe (RS485)
- Backup moisture, pH and temperature probes
- Air temperature and humidity
- Battery level reporting
LoRaWAN node
For large farms with no Wi-Fi. A gateway covers many kilometres of open ground.
- Compact 15-byte message
- Works with The Things Network and ChirpStack
- Years of battery life at long intervals
Handheld probe (Bluetooth)
Walk the field, push the probe into the soil, press the button and see the result on your phone.
- Instant soil health score
- GPS stamp for every scan
- Save scans to your AgriSense account
Sensor accuracy depends on calibration and soil type. Nitrogen, phosphorus and potassium from low-cost probes are indicative only. We calibrate each kit and recommend a lab test for fertiliser decisions.

Frequently asked questions
Need help choosing a kit? Contact us and an agronomist will reply.
How accurate are the readings?
Moisture, soil temperature and salinity are reliable once the probe is calibrated for your soil. pH and especially nitrogen, phosphorus and potassium from low-cost probes are indicative. Use them to spot trends and problem areas, and confirm fertiliser decisions with a lab test.
Do I need internet in the field?
Wi-Fi nodes need a Wi-Fi signal or a mobile hotspot. LoRaWAN nodes only need a LoRaWAN gateway, which can be placed on the farm or use a public network. The handheld probe works over Bluetooth and the phone uploads when it is online.
Does it work with the satellite service?
Yes. Soil readings and satellite crop health sit in the same AgriSense account, so you can check a low-NDVI area against the soil moisture or salinity measured there.
Can I add drone or camera photos?
Yes. Photos taken in the app, or uploaded from a drone survey, are stored against the device or field with their GPS position.
Is my data private?
Your readings belong to your account. Each device has its own key, passwords are stored hashed, and the service runs over HTTPS. See our privacy page.
