Which soil parameters does the H Series measure?

Soil moisture (0–100%, ±3%), temperature, conductivity (0–1,000 µS/cm, ±3%), pH (0–14, 0.01 pH resolution) and NPK nutrients (0–1,999 mg/kg, ±2% F.S.) — all in a single probe.

Can the probe stay buried outdoors year-round?

Yes. The IP68 enclosure is designed for long-term burial, and the battery is designed for more than 10 years of life at a one-hour reporting interval under specified test conditions, which reduces routine maintenance between seasons.

How is soil data transmitted?

Over 4G or NB-IoT with MQTT uplink to Hitelecom Cloud or a private platform; thresholds on any parameter trigger alerts.

Is it suitable for alkaline or saline soils?

The EC channel covers 0–1,000 µS/cm, which suits most farmland; for highly saline soils or special media, contact Hitelecom for a customized range.

H Series · Soil Sensor

Low Power | Precision | Multi-parameter

The Hitelecom H Series soil sensor is a multi-parameter wireless probe for agriculture and land monitoring. One device measures soil moisture, temperature, conductivity (EC), pH and NPK nutrients, reports over 4G or NB-IoT, and is designed for more than 10 years of battery life at a one-hour reporting interval under specified test conditions, with an IP68 enclosure designed for long-term burial.

Applications

This product supports the following monitoring applications:

Farmland irrigation scheduling

Soil moisture trends tell growers exactly when and how much to irrigate, cutting water waste.
Greenhouse fertigation

EC and NPK readings guide fertilizer dosing so nutrients stay in the root zone, not in runoff.
Urban parks and landscaping

Monitors lawn and tree-pit soil moisture for municipal greening maintenance crews.
Soil pollution and remediation tracking

Continuous pH and EC logging flags contamination plumes and verifies remediation progress.
Forest and grassland health

Long-term buried probes track soil drought stress ahead of visible canopy decline.
Research and field trials

Multi-parameter time series support agronomy research and variety trials.
