The GXF-402 series ultrasonic anemometer developed by Zhongke Yinhexin is a five-in-one digital environmental monitoring equipment. It can accurately measure ambient wind speed, wind direction, temperature, humidity and atmospheric pressure. Adopt advanced ultrasonic measurement technology, support MODBUS protocol, digital result output, support RS485, RS232 or TTL/CMOS UART interface. Allow 6V-30V wide voltage power supply input. Applicable to meteorological observation, environmental monitoring, industrial control environment monitoring and other fields, it is a new generation of multi-functional environmental sensor for the Internet of things.
