PE Probe Temperature and Humidity Sensor Module with OLED Display ModBus RTU RS485 4-20mA 0-10V Industrial Sensors Transmitter

2.1 Product Overview

This product adopts high-precision temperature and humidity sensor probes and high-performance microprocessors, which can accurately measure the temperature and humidity in the air, meeting the application requirements of various industries for customers.

(2) This product follows the standard ModBus RTU protocol and the address and baud rate can be flexibly modified using the upper computer software. This product, when used in conjunction with the 485 to network conversion module, can transmit data to the cloud server.

2.2 Functional Features

(1) It adopts high-precision digital temperature and humidity sensors, with a wide DC voltage supply of 12-24V and a power consumption of less than 1 watt.

(2) It adopts imported RS485 chips from well-known brands to provide multiple protections for the interface, including surge prevention, circuit connection error prevention, and hardware watchdog design, ensuring stable operation of the equipment and avoiding system crashes.

(3)RS485 interface, standard Modbus RTU protocol, can be transferred to 485-to-4G/Ethernet modules.

(4) Provide upper computer debugging software. Users can modify the device address (range 0 to 255), baud rate (range 4800bps to 9600bps), and verification method by themselves. Moreover, these Settings can be saved after power failure.
