The sensor is dust-proof, anti-leaching, and adopts aviation joints. It can be directly replaced during maintenance without repeating wiring. 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. 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. colour: black and silver Material: Metal size: Cable Length: 1.5m Package Contents: 1 x Soil Moisture Sensor Only the above package content, other products are not included.
