L3 Soil Moisture Sensor



Free Shipping

Monitor the soil moisture and air temperature of any outdoor crop, anywhere, anytime. Perfect for irrigation management, EarthScout L3 Soil Moisture Sensor uses cellular IOT smart farming technology to send hourly soil moisture readings to the EarthScout app on your phone. It can be configured to run up to 3 research-grade precision agriculture probes at a time to monitor soil moisture, soil temperature, soil EC, air temperature, and humidity - helping you maintain the ideal amount of water, nutrients, and pest protection for your crops. It's easy to use and install. For irrigation set your high and low soil moisture limits (e.g. 19% and 14%) in the EarthScout app and it notifies you when soil moisture hits your limits, then adjust irrigation accordingly. L3 Soil Moisture Sensor quickly pays for itself, saving growers an average of 25-50% on irrigation costs, while reducing management time and improving crop quality. Qualifies for most state and federal water conservation rebates. Compare EarthScout Products.
