In plain terms

What Is a LoRaWAN Soil Moisture Sensor?

A LoRaWAN soil moisture sensor is a battery-powered probe buried in the root zone that measures how much water the soil is holding — its volumetric water content, or VWC — and transmits those readings kilometres over a LoRaWAN® network to your dashboard or irrigation controller. One gateway can serve an entire farm, so a field can be instrumented without trenching, mains power, or cellular coverage at each point.

The MacSync LSS X2 is the industrial version of that idea. It measures 0–100% VWC by capacitive sensing to ±3% accuracy, reads soil temperature to ±0.5 °C, responds in under 10 seconds, and runs 7+ years on a single 19 Ah cell at hourly reporting — or indefinitely on the 20 W solar variant. Its 85 mm stainless steel probe is rated IP68 for permanent burial and connects on a standard 1 metre cable to the IP65 sensor unit above ground, and it reads reliably in clay, sandy, red and saline soils as well as cocopeat and greenhouse media.

Why Macnman

How Deep Should a Soil Moisture Sensor Be Installed?

Most irrigation deployments place the probe in the active root zone — commonly around 15 cm deep and about 5 cm to the side of a drip emitter — with a second sensor deeper if you want to see water moving past the roots. Allow 10 to 14 days after installation for the soil to settle back around the probe before you trust the readings for scheduling.

IP68 Stainless Steel Probe, IP65 Sensor Unit

The 85 mm stainless steel probe is IP68 rated for permanent burial, and the glass-filled nylon MacSync unit above ground is IP65. Both operate from −40 °C to +80 °C, and a standard 1 metre cable separates them — engineered to stay in the ground through irrigation cycles, monsoons and harvest.

Outcomes

Soil moisture readings are a trigger, not just a record — irrigation controllers, alerts and agronomy decisions all act on them in real time.

Cut Water Use

Irrigate when the root zone actually needs it instead of on a fixed schedule — the same crop on measurably less water.

Water saving

Prevent Over-Irrigation

Threshold alerts fire before saturation, protecting roots from waterlogging and stopping nutrients leaching past the root zone.

Crop health

Automate Irrigation

Feed live VWC readings to your controller or platform so valves open on soil condition, not on a timer.

Automation

Prove What Worked

Season-long soil moisture and temperature history turns agronomy decisions into data you can review and repeat.

How it works

How Does a LoRaWAN® Soil Moisture Sensor Work?

Step 1 of 5

Place the probe in the root zone

Auger a hole, insert the probe at root-zone depth, and backfill so the soil sits firmly against it — no trenching and no power run.

Reporting modes

Three Reporting Modes for Every Irrigation Strategy

Fixed-interval uplinks you set from 1 minute to 24 hours. Hourly suits most field irrigation and is what delivers 7+ years of battery life.

Note: Shorter intervals shorten battery life — 5-minute reporting gives roughly 2 years.

RF performance

Stable Readings Across Clay, Sand and Saline Soils

Capacitive sensing measures the soil's dielectric response rather than its conductivity, so readings stay consistent in heavy clay, free-draining sand, cocopeat and fertigated ground where resistive probes drift as salts build up. The optimized internal antenna holds the LoRaWAN® link through dense canopy, polyhouse structures and pump-house interference.

Solar vs Battery Soil Moisture Sensor — Which Should You Deploy?

All three variants share the same 85 mm stainless steel IP68 probe, the same accuracy and the same LoRaWAN® radio. The difference is how they are powered, and that decides where each one belongs.

0.1Four steps to live soil data
1
Augering a hole for the MacSync soil moisture sensor probe

Auger the hole

Open a hole at root-zone depth — around 15 cm for most row crops, deeper for tree crops — sized to take the 85 mm probe.

2
Inserting the MacSync LSS X2 soil probe and backfilling

Insert and backfill

Seat the full 85 mm of the stainless steel probe against undisturbed soil and backfill firmly so there are no air gaps around it.

3
Configuring the MacSync soil sensor with the Maya app

Pair with Maya over BLE

Set the uplink interval, sampling rate and moisture thresholds from your phone.

4
Soil moisture readings arriving on a LoRaWAN dashboard

Let it settle, then schedule

Readings stabilise as the soil re-consolidates — allow 10 to 14 days before driving irrigation decisions from them.

Range & reliability

Long-Range LoRaWAN® Coverage Across the Whole Farm

Reliable communication up to 15 km line-of-sight range for large sites and campuses

One gateway reaches sensors spread across fields, plantations and orchards — kilometres of range at 23 dBm with −137 dBm sensitivity, so a single installation covers ground that would need dozens of Wi-Fi access points or SIM cards.

FAQ

Frequently asked questions

Place the probe in the active root zone — commonly around 15 cm deep for row crops and about 5 cm to the side of a drip emitter, deeper for tree crops. Many growers add a second sensor below the root zone to see whether water is draining past the roots. Allow 10 to 14 days after installation for the soil to re-consolidate around the probe before using the readings to schedule irrigation.

The MacSync LSS X2 probe is 85 mm long and machined from stainless steel, rated IP68 for permanent burial. It connects to the sensor unit on a standard 1 metre cable, so the probe sits in the root zone while the radio and battery stay above ground; longer IP68 cable extenders are available for deeper placements. Seat the full 85 mm against undisturbed soil and backfill firmly so no air gaps remain around it.

VWC is the proportion of a soil volume that is water — 25% VWC means a quarter of that soil volume is water. It is the measurement irrigation scheduling actually uses, because it tells you how much water is available to the roots. The MacSync LSS X2 measures 0–100% VWC to ±3% accuracy between 0 and 53% VWC.

The MacSync LSS X2 runs 7+ years on its 19 Ah Li-SOCl₂ cell at hourly reporting, about 4 years at 15-minute reporting, and roughly 2 years at 5-minute reporting. For sites that need frequent readings indefinitely, the solar variant pairs a 20 W panel with an 8000 mAh rechargeable battery.

Yes. It uses capacitive sensing with no exposed electrodes, so it stays stable in clay, sandy and red soils, in cocopeat and greenhouse media, and in saline ground where conductive probes tend to drift or corrode.

Yes — LoRaWAN sensors report through a gateway, but you only need one for a very large area. A single gateway typically covers an entire farm, plantation or orchard, and Macnman supplies both indoor and outdoor LoRaWAN gateways if you do not already have coverage.

It works with The Things Network (TTN), ChirpStack, MQTT platforms, Orbiwise, Netmore and private on-premise LoRaWAN servers. It supports LoRaWAN® v1.0.4, Class A by default with Class C configurable, OTAA activation and AES-128 encryption.

Soil temperature is measured to ±0.5 °C across a −40 °C to +80 °C range, with response in under 10 seconds — accurate enough for germination windows, frost-risk alerts and root-zone temperature studies.

Yes. Configure soil moisture and temperature thresholds in the Maya app and the sensor sends an immediate uplink when the root zone crosses one. Your platform or irrigation controller acts on that event, so valves open on soil condition rather than on a timer.

It depends on how uniform the field is. A common starting point is one sensor per irrigation zone or management block, placed in a representative spot, with additional sensors where soil type, slope or crop stage differ. Because one gateway serves many sensors, adding more points costs only the sensor.

Pair over Bluetooth with the free Macnman Maya Android app to set uplink interval, sampling rate, reporting mode and thresholds — no laptop needed. Devices already in the field can be reconfigured over the air with downlink commands, and firmware updates are signed.

Yes. It performs in cocopeat and other growing media as well as field soil, and the battery variant suits covered structures where a solar panel would see little light. Threshold alerts are commonly used to protect high-value crops from both dry-down and over-watering.

Five: solar-powered and battery-powered versions on LoRaWAN® (SKUs 8805 and 8806), the same two on Macnman's MacTalk device-to-device protocol (8807 and 8808), and a BLE variant for local monitoring and commissioning (8809).
