Features 1.MEASURING RANGE: Soil moisture and temperature sensor, with a temperature measuring range of -20-100℃ and a humidity measuring range of 0-100%RH, with high accuracy and good reliability. 2.MULTIPLE FUNCTIONS: This soil sensor has strong functionality, complete calibration, digital output, IIC serial interface, easy to integrate, the relative humidity of the air is a function of temperature. 3.304 STAINLESS STEEL: The sensor housing is made of 304 stainless steel material, which is corrosion and oxidation resistant, with IP67 waterproof grade, and can be used in harsh environments. 4.3 METER CABLE: The soil temperature and humidity sensor is equipped with a 3 meter extension cable, which is unrestricted in use location and space, and can be used for a wider range. 5.APPLICABLE SCENES: The sensor is applicable to weather station, warehouse, construction site, concrete block detection, agricultural greenhouse, flower nursery, plantation and other places. Specification Item Type: Soil Moisture Sensor Model: FS304 SHT30 Working Current: <10mA Humidity Accuracy: ±2%RH Temperature Accuracy: ±0.2℃ Working Voltage: 3.3V 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.
