Soil sensor that measures and monitors soil temperature and humidity to support plant growth. The soil temperature measurement range is 14°F to 140°F, and the soil moisture measurement range is 0% to 100%. Enables intelligent application control: if the sensor detects soil moisture exceeding the set threshold, the watering timer automatically stops irrigation. This threshold can be manually adjusted. The sensor records soil temperature and humidity data for the last 10 days, which can be viewed in graph format via the mobile app. Easy to use: connect the soil temperature and humidity sensor to the smart irrigation timer via Bluetooth through the mobile app. Features a durable plastic housing with a stainless steel probe and an IP65 waterproof rating for long-lasting performance. Powered by 4 AAA batteries (not included), providing up to one year of operation without frequent replacement. Material: plastic. Color: green. Package includes: 1 x Soil Moisture Sensor. No other items included. Note: Lighting conditions and display settings may cause slight variations in color between the image and the actual item. Measurement error allowance is +/- 1-3 cm.
