1、SPECIFICATIONS: Soil temperature humidity sensor with 3 meter cable, full calibration, digital output, IIC serial interface for easy integration, relative humidity of air as a function of temperature. 2、WORKING RANGE: Used for measuring soil temperature and humidity, with a temperature measuring range of ‑20‑100℃, ±0.2℃ accuracy, a humidity measuring range of 0‑100%RH, ±2%RH accuracy. 3、WIDE APPLICATION: The soil sensor can be used in HVAC, weather station, warehouse, construction site, concrete test block detection, agricultural greenhouse, nursery planting and other places. 4、GOOD PROTECTION: The soil sensor shell is made of 304 stainless steel, with IP67 waterproof grade, rust resistance and corrosion resistance, and can be used in various harsh environments. 5、PORTABLE DESIGN: The temperature and humidity sensor probe has a small size, light weight, easy installation and portability, unrestricted usage, which is convenient and practical. Item Type: Soil Temperature Humidity Sensor Model: FS304 SHT31 Working Current: <10mA Humidity Accuracy: ±2%RH Temperature Accuracy: ±0.2℃ Temperature Measurement Range: -20-100℃ Humidity Measurement Range: 0-100%RH Comm Interface: I²C Working Condition: -40-125℃, 0-99%RH Storage Condition: -20-80℃, 0-95%RH Shell Material: 304 Stainless Steel Waterproof Grade: IP67 Cable Length: Approx. 300cm / 118.1in Working Condition: The sensor performs normally within the recommended operating range. Long term exposure to conditions outside the normal range, especially when humidity exceeds 80%, may cause temporary signal drift (after 60 hours drift x 3%RH). After returning to normal operating conditions, the sensor will slowly self recover to the calibration state. Prolonged use under abnormal conditions can accelerate the aging of the product. 1 x Soil Temperature Humidity Sensor
