Features: This soil temperature and humidity sensor is a digital output with a resolution of up to 14bits and is self-calibrating internally, eliminating the need for calibration. The combination of temperature and humidity is convenient for dew point measurement, with high reliability and long-term stability. The product is compact in structure and I2C output, suitable for field application and product integration. Because the brass structure can be used in high temperature and high humidity environment, the temperature resistance is higher than that of the plastic case. The sensor is dust-proof, anti-leaching, and adopts aviation joints. It can be directly replaced during maintenance without repeating wiring. Applications: computer room monitoring, HVAC, weather station, warehouse, construction site, concrete test block inspection, agricultural greenhouse, flower nursery, etc. Specification: Item Type:Soil Sensor Working Current:80%, may result in temporary signal drift (after 60 hours drift +3% RH). When returning to normal After the working conditions, the sensor will slowly return to the calibration state. Prolonged use under abnormal conditions will accelerate the aging of the product. Humidity sensors are not ordinary electronic components and require careful protection. This must be taken seriously by users. Prolonged exposure to high concentrations of chemical vapour will cause the sensor reading to drift.
