RS485 Sensor Node

The RS485 Sensor Node is an IoT device designed for applications like intelligent agriculture, environment monitoring, and home automation. It features a 6-channel analog input and a SHT1x Humidity & Temperature digital input. Using the RS-485 protocol, it supports up to 254 nodes at a distance of 1200 meters between each node, making it ideal for wide-range environmental monitoring. Its screw-free design ensures reliable and stable connections. The RS-485 standard is effective for long-distance communication in electrically noisy environments, making it suitable for industrial use. This node enables the creation of cost-effective local networks and communication links, offering data transmission speeds of 35 Mbit/s up to 10 meters and 100 kbit/s at 1200 meters. It is more efficient than RS-232 and can be integrated with Ethernet for a robust Internet of Things setup. A USB to RS422/RS485 adapter is available for those without an Arduino.
