Wireless Battery-Powered Soil Moisture Sensor Usage: The Key to Water Management in Modern Agriculture
In modern agriculture, the efficient use of water resources is becoming more critical by the day. Especially for agricultural enterprises operating in arid and semi-arid regions, accurately determining the plant's actual water need is vital for both yield and costs. At this point, esular wireless soil moisture sensor stands out as an indispensable part of smart irrigation management.
What is a Soil Moisture Sensor and How Does It Work?
A soil moisture sensor is a smart device that measures the amount of moisture in the soil and makes this data usable in a digital environment. Sensors precisely measure moisture values at different depths through probes placed in the soil.
Esular wireless soil moisture sensor analyzes the dielectric property of the soil using capacitive, resistive, and TDA measurement techniques. This technique is based on the difference in electrical properties between dry soil and wet soil. The measured data is reliably transmitted up to a distance of 5-10 km with wireless LoRa/LoRaWAN technology.
Graduated Measurement System: Understand the Real Needs of Plant Roots
Plant roots take water and nutrients from different depths. Therefore, measuring only surface moisture is not enough. Esular wireless soil moisture sensor performs graduated measurements at 2, 3, or 4 different depths (30-60-90-120 cm) and tracks:
- Surface soil moisture
- Middle layer moisture status
- Deep root zone moisture level
separately. In this way, you can clearly see to what depth irrigation reaches, the moisture distribution in the root zone, and how much water the plants actually need.
Advantages of the Wireless Battery-Powered Soil Moisture Sensor
1. Energy Independence and Easy Installation
One of the biggest problems in agricultural lands is energy and cabling costs. Esular wireless soil moisture sensors completely eliminate this problem:
- Produces its own energy with a built-in solar panel
- Works uninterruptedly for up to 5 years with a 3.6V rechargeable lithium-ion battery
- Requires no cabling – installed in minutes with a "Plug and Play" logic
- Can be used even in remote agricultural areas without electricity infrastructure
2. Water and Energy Savings
The most obvious benefit of using a wireless soil moisture sensor is water savings. Unnecessary and excessive irrigation:
- Depletes water resources
- Increases electricity costs
- Degrades soil structure
- Leads to oxygen deficiency in the plant root zone
- Causes leaching of nutrients
In field applications conducted with the Esular system, an average of 30-50% water savings and accordingly up to 40% electricity savings were achieved.
3. Yield Increase and Plant Health
Every plant's critical irrigation period and water need are different. Insufficient or excessive irrigation:
- Leads to yield losses
- Leads to a decrease in product quality
- Leads to a decrease in resistance against diseases and pests
By irrigating according to the real needs of the plant with the wireless soil moisture sensor, you can achieve healthy and productive production.
4. Remote Monitoring and Control
Thanks to the Esular mobile application:
- Follow all sensor data instantly from your phone
- Receive automatic alarms at threshold values you set
- Analyze and compare historical data
- Make your irrigation decisions based on data
- Manage remotely without being in your field
Fertilizer Management with EC (Electrical Conductivity) Measurement
Esular wireless soil moisture sensor also performs EC (Electrical Conductivity) measurement in addition to moisture measurement. The EC value shows:
- Salt concentration in the soil
- Fertilizer density
- Nutrient level
However, an important point to note: the soil must be moist for EC measurement. EC measurement cannot be taken in dry soils. The sensor, which measures in µs/cm, can be used safely in open field, greenhouse, and garden conditions thanks to its long-lasting carbon electrodes. This way, you can also make your fertilization decisions based on data and prevent unnecessary fertilizer use.

Installation and Usage: Step by Step
1. Sensor Placement
Place the sensor at a representative point. Choose an area close to the tree/plant root line where irrigation pipes are ineffective. Prefer a location where the soil type is homogeneous.
2. Placing Probes into the Soil
Carefully insert the probes to the desired depths (30-60-90 cm). Make sure there are no gaps between the soil and the probe. Compact the soil slightly before the first measurement.
3. Central Unit Installation
Mount your central unit (gateway/control device) at a suitable point. Ensure that the GSM signal and communication with the sensors are good.
4. Mobile Application Setup
Download the Esular mobile application, register your system, and define the sensors. Set your threshold values and alarm settings.
