Temperature and humidity sensor Modbus RTU intelligent temperature and humidity transmitter instructions

One Product Function Introduction:

This product is equipped with a high-precision digital probeCPUComposition of communication circuits. Adopting imported high-precision temperature and humidity probes and intelligent transmitter portsRS232perhapsRS485Output, collect temperature and humidity, and convert temperature status tomodbus RTUOutput. It can be directly connected to secondary instruments, collectors, human-machine interfaces, and computers. It has the characteristics of high accuracy, reliability and stability, long service life, and long communication distance, making it a good choice for networked centralized monitoring of temperature and humidity.

II Application areas:

Communication base stations, archives, warehouses, laboratories, factories, workshops, computer rooms, museums, archives, libraries, hospitals, hotels, residential areas, petrochemical bases, power plants, nuclear power plants, substations, agricultural research bases, health and epidemic prevention stations, environmental protection departments, vegetable greenhouses, incubation farms, etc.

III Function Introduction：
