Soil moisture sensor SM100

dielectric

The SM100 volumetric soil moisture sensor determines soil moisture using two electrodes that function as a capacitor. The soil surrounding the electrodes acts as the dielectric material, and an 80 MHz oscillator drives the capacitor. The sensor measures soil moisture by detecting changes in dielectric permittivity, which is directly influenced by the amount of water in the soil. Water has a significantly higher dielectric permittivity compared to air, soil minerals, or organic matter, allowing the sensor to accurately detect moisture levels. Advantages: Real-time moisture monitoring: With SM100, you can accurately monitor soil moisture levels in real-time, with measurements as frequent as every 1 minute. Improved irrigation planning: By tracking the depletion of water in the soil, you can optimize your irrigation schedule and ensure efficient water use. Enhanced decision-making: The sensor provides reliable data, helping you assess the impact of rainfall and irrigation on your field over time. Why choose SM100? Regular use of the SM100 sensor gives you a clear, long-term picture of soil moisture changes, helping you make informed decisions about water management and crop health. Installation and Best Practices for the SM100 Soil Moisture Sensor To ensure accurate measurements, it’s important to carefully choose the sensor placement and correctly install the SM100. Sensor Placement: Place the sensors in the effective root zone of your crops. This will give you a representative view of soil moisture on the field.
