L3 Plus Cellular Soil Moisture Sensor with Irrigation App


Free Shipping

Monitor the soil moisture, air, and light conditions of any crop, anywhere, anytime. Perfect for irrigation management & water conservation, EarthScout L3 Plus uses cellular IOT smart farming technology to send hourly soil moisture readings to the EarthScout app on your phone or laptop. Run up to 5 research-grade precision agriculture probes at a time to monitor soil moisture, temperature, EC, air temperature, humidity, and solar radiation - and maintain the ideal amount of water, nutrients, and pest protection for your crops. TDR Soil Moisture Sensors are easy to install, accurate, and don’t disturb the soil.
For irrigation, set your low and high soil moisture range in the EarthScout App (e.g. 9.5% - 16%) and the app will display the real-time soil moisture percent, the inches of water needed to reach 16% moisture, and the dry down distance to 9.5%. L3 Plus Cellular Soil Moisture Sensor helps you reduce irrigation costs, and qualifies for most state and federal water conservation rebates. Compare EarthScout Products.
