Temperature and humidity recorder

The temperature and humidity recorder is also called the outdoor rain- and snow-proof 485 temperature and humidity recorder. The temperature and humidity recorder is an industrial wall-mounted high-protection grade enclosure with an IP65 protection grade. It is rain- and snow-proof and has good breathability. 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.
