Melnor Gray Rain Sensor

Make sure you don’t over water the tomatoes or run the sprinkler in the rain. The hydro logic soil moisture sensor monitors how wet the soil is to automatically skip watering when it rains or the soil is too damp. When the soil is dry enough, the timer will resume to the original schedule. You can select the exact moisture level you want to pause the watering, depending on your plant’s needs. The hydro logic moisture sensor works with select Melnor hydro logic water timers to maintain healthy growth while preventing damage and waste from winterization.
