Soil Moisture Sensor Digital Soil Temperature Humidity Probe I²C Output 3 Meter Cable DC3.3V FS304 SHT3X 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.
