RS485 temperature and humidity sensor

RS485 temperature and humidity sensor

Product Overview

The temperature and humidity sensor has the function of collecting 1 channel of temperature, 1 channel of dew point temperature, and 1 channel of humidity. It adopts the standard Modbus RTU communication protocol and can remotely collect temperature and humidity data via the RS485 bus. It is applicable to scenarios such as the monitoring of the machine room environment in data centers, machine room micro - modules, and enterprise machine rooms for temperature and humidity monitoring.

DIP switch instructions

The slave ID be set through the DIP switch. its address setting range is 1 - 63

When the switch is toggled upwards to ON, the switch takes effect.

Example of switch setting: When switches 1, 3, and 5 are toggled to the ON position, value is 1+4+16 = 21. That is, the slave ID is set to 21.
