Temperature and Humidity Sensor
The temperature and humidity sensor is rain-proof and snow-proof with has IP65 high-protection shell and good air permeability. The circuit uses industrial microprocessor chips imported from the United States and imported high-precision temperature sensors to ensure excellent reliability, high precision and interchangeability of the products. The output signal type is RS485, which can communicate up to 2000 meters.
