Soil sensor 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%. Features intelligent application control: if the sensor detects soil moisture exceeds the set threshold, the watering timer automatically stops irrigation. This threshold can be manually adjusted. The device records soil temperature and humidity data for the past 10 days and displays it in graph format via the mobile app for easy monitoring. Easy to use: connect the soil temperature and humidity sensor to the smart irrigation timer via Bluetooth through the mobile app. High-quality construction with a durable plastic housing and stainless steel probe, rated IP65 for water resistance, ensuring long-term durability.
