Description
The RS-485 Sensor Node module, a versatile device suitable for a wide range of applications including intelligent agriculture, environment monitoring, and home automation, among others. This module is an integral part of the Internet of Things (IoT) ecosystem.
Equipped with 6 channels of analog input and 1 SHT1x Humidity & Temperature digital input, the RS-485 Sensor Node provides comprehensive data collection capabilities. Its support for the RS485 protocol allows for the connection of up to 254 nodes, with a maximum distance of 1200 meters between each node. This extensive coverage enables efficient monitoring of various environments. With its screw-free design, the module facilitates easy cable connection while ensuring reliability and stability. This feature eliminates the need for additional tools, making installation hassle-free.
The RS-485 standard excels in long-distance communication and is highly resistant to electrical noise, making it ideal for deployment in industrial environments and similar applications. Its multi-drop configuration allows multiple receivers to be connected to the network. These characteristics contribute to its popularity and effectiveness in the industry.
Compared to the RS-232 bus, the RS-485 bus offers greater cost-effectiveness and extended communication range. By integrating RS-485 with Ethernet, which is widely available worldwide, the goal is to establish a cost-effective and highly efficient network. This integration enables seamless coordination among devices.
Additionally, if an Arduino board is not readily available, DFRobot offers a USB to RS422/RS485 adapter for your convenience.
