Revolutionizing Soil Moisture Monitoring with Milesight EM500-SMTC Soil Sensor


Why Monitoring Soil Moisture?

Monitoring soil moisture and other environmental soil variables is crucial for optimizing plant growth, conserving water resources, managing nutrient levels, and maintaining soil health. By tracking these parameters, farmers and gardeners can ensure that their crops receive the appropriate amount of water and nutrients, avoid overwatering, adjust their fertilizer applications as needed, and assess the overall health and productivity of their soil. Ultimately, monitoring soil conditions is essential for achieving long-term sustainability and maximizing crop yields.

The Difficulties Monitoring Soil Conditions

However, monitoring soil moisture and other conditions (such as temperature and electrical conductivity) can be a challenging task, and several factors can make it difficult to achieve accurate and reliable results.

  • Maintenance

One of the major difficulties in monitoring soil conditions is the maintenance of the sensors. Regular calibration, cleaning, and replacement of parts are necessary to ensure accurate readings, which can be a time-consuming and costly process. Failure to maintain the sensors can lead to inaccurate measurements, rendering the monitoring efforts useless.

  • High Cost

The cost of soil moisture and temperature monitoring equipment can be a significant challenge, especially for small-scale farmers or those with limited budgets. Investing in high-quality sensors and equipment can be crucial for accurate monitoring, but it may be out of reach for some farmers, leaving them without access to critical data for optimizing plant growth and conserving water resources.

  • Installation:

The installation of soil sensors is a complex process that requires careful consideration of various factors such as soil type, depth, and location. In rocky or hard soils, the installation can be particularly challenging, requiring specialized equipment and expertise. Even in ideal conditions, improper installation can result in inaccurate readings, making it essential to have the right skills and knowledge to ensure successful installation and reliable monitoring.

Except for these challenges, regular monitoring of soil conditions also is crucial for optimizing crop yields, conserving water resources, and achieving long-term sustainability.

Milesight EM500-SMTC Soil Moisture Sensor


Milesight EM500-SMTC is a LoRaWAN®-enabled sensor designed explicitly for soil moisture,  temperature and electrical conductivity monitoring, which can help solve the difficulties of monitoring soil moisture and temperature mentioned earlier. Here are some features of the EM500-SMTC sensor that can help:
