The XY-MD02 utilizes an industrial-grade chip and high-precision SHT20 sensors for temperature and humidity. This guarantees the product’s reliability, precision, and interchangeability. It uses the RS485 hardware interface with lightning protection and is compatible with the standard industrial Modbus RTU protocol on the protocol layer. The product combines MODBUS and ordinary UART communication protocols, allowing you to choose between them. The UART communication features an automatic reporting function and can output temperature and humidity by connecting to the RS485 serial interface mode tool.
