Temperature and humidity recorder

The Temperature and Humidity Recorder is an industrial wall-mounted high-protection enclosure with an IP65 protection grade, which is rain- and snow-proof and has good breathability, with the function of measuring temperature and humidity.. The circuit uses industrial-grade microprocessor chips imported from the United States and imported high-precision temperature and humidity sensors to ensure excellent reliability, high precision and interchangeability of the product. The output signal type is RS485, which can communicate up to 2000 meters. The standard modbus protocol supports secondary development.
