In the wave of Industry 4.0 and the Internet of Things (IoT), the accurate collection and efficient transmission of environmental data have become the foundation of digital transformation for enterprises. The Modbus temperature and humidity sensor, with its standardized protocol, high compatibility, and industrial-grade reliability, is becoming a core component in smart factories, green agriculture, smart buildings, and other fields. This article will explain the technical highlights and industry value of the RS485 temperature and humidity sensor (EID041-G01S)
Product Advantages
Built-in Imported Temperature and Humidity Sensor Chip (SHT30)
The SHT30 is known for its high precision and can provide very accurate temperature and humidity readings. The temperature measurement accuracy reaches ±0.2°C, and the humidity measurement accuracy is ±2% RH.
Modbus RTU Protocol Communication
As one of the most widely used communication protocols in industrial applications, the Modbus RTU module can be easily integrated into existing industrial control systems. Users do not need complex programming or additional hardware support to achieve interoperability between the module and other devices. It can be directly connected to PLCs, SCADA systems, and configuration software (such as Siemens, Mitsubishi, and Kunlun Tongtai devices).
RS485 Interface Communication
The RS485 supports long-distance data transmission, theoretically reaching up to 1200 meters, which is much farther than RS232 and other standards. RS485 supports the construction of multi-point networks, allowing multiple devices to share the same communication bus, reducing wiring requirements and costs. The differential signal transmission method makes RS485 highly resistant to interference in noisy environments, making it particularly suitable for industrial applications. The RS485 protocol is relatively simple and easy to integrate into existing systems.
Support for Modbus Address and Adjustable Baud Rate
In the same Modbus network, different slave device addresses can be set to easily expand the system scale and add more devices without conflicts. Each device can be quickly located and troubleshooted without affecting the normal operation of other devices.
The baud rate (data transmission rate) can be selected based on actual needs, maximizing data transfer efficiency while ensuring communication quality. In environments with heavy noise interference, a lower baud rate can be chosen to improve communication reliability, while a higher baud rate can be used in scenarios requiring higher real-time performance to speed up data exchange.
Pluggable Terminal Blocks
The pluggable terminal blocks significantly simplify the installation and disassembly of electrical connections, eliminating the need for screw fastening and complex steps, saving time and labor. When maintenance or component replacement is required, the pluggable terminal blocks allow for quick disconnection and reconnection, reducing system downtime. The ability to quickly assemble and replace components allows equipment manufacturers to adopt a modular design approach, improving production flexibility and efficiency. Because no tools are required for connection and disconnection, the risk of safety hazards caused by improper tool use is reduced.
Supports Positioning Holes and DIN Rail Mounting
The device supports two installation methods: positioning holes and DIN rail. Positioning holes allow for precise positioning and fixing with screws or other fasteners, ensuring that the device or component is installed according to design requirements. The DIN rail mounting method typically supports quick insertion and removal, greatly facilitating the installation and maintenance of devices. The design that supports both positioning holes and DIN rail mounting provides users with a more comprehensive and flexible solution.
Wide Voltage Power Supply with Reverse Polarity Protection
The device supports a wide DC voltage input from 5V to 36V, making it compatible with a variety of power supply schemes. This gives more freedom when designing systems, without the need for additional design adjustments to match specific power supply specifications. The reverse polarity protection mechanism effectively prevents damage caused by incorrect polarity connections, greatly enhancing the safety of usage. It reduces the risk of hardware failure due to operator errors and, in turn, lowers maintenance and service costs.
Wide Temperature Measurement Range
The device supports a temperature measurement range from -40°C to +125°C, making it well-suited for a variety of complex environments and providing an effective solution to expand its application scope.
