8 in 1 Soil Sensor – Temperature, Moisture, EC, Salinity, pH, NPK sensor
$272.00
The 8 in 1 Soil Sensor is an advanced solution for precise soil monitoring, capable of measuring eight critical parameters simultaneously: moisture, temperature, electrical conductivity (EC), salinity, pH, nitrogen (N), phosphorus (P), and potassium (K).
This high-sensitivity sensor helps optimize irrigation, improve soil health, and support scientific research with real-time data access via GPRS, 4G, Wi-Fi, LoRa, or LoRaWAN. Paired with compatible servers and software, it enables real-time data access on a PC.

Product Usage
Soil Surface measure method
- Choose a representative soil sample area and clear away debris and vegetation.
- Insert the sensor vertically and fully into the soil.
- Relocate if hard objects obstruct the insertion, and repeat the measurement.
- For more reliable data, measure at multiple points and calculate the average.
Buried measure method
- Create a vertical soil profile slightly deeper than the sensor’s lowest installation depth, about 20–50 cm in diameter.
- Insert the sensor horizontally into the soil profile.
- Refill the excavated soil in layers, compacting it to ensure horizontal placement.
- To maintain soil moisture consistency, bag and label removed soil for reverse backfill if feasible.
Six – Tier Installation
Three – Tier Installation
Measure notes
- Use the sensor in environments with 20–25% soil humidity.
- Ensure all probes are fully inserted into the soil during use.
- Protect the sensor from excessive heat and lightning.
- Avoid pulling or striking the sensor or its wires.
- Rated IP68, allowing immersion in water.
- Do not leave the sensor powered in open air for extended periods due to electromagnetic radiation interference.
