RS485 Sensor Node V1.0

INTRODUCTION

This RS-485 Sensor Node module can be used in various applications such as intelligent agriculture, environment monitoring, home automation...etc. It is a Internet of things device. This RS-485 Sensor node provides 6 channel analog input and 1 SHT1x Humidity & Temperature digital input. The RS485 protocol supports up to 254 nodes at 1200m distance between each node. This allows a wide range cover for monitoring the environment.  A screw free design allows easy connection of cables without scarfice reliable & stable.

RS-485 standard is used effectively over long distances and in electrically noisy environments. Multiple receivers may be connected to such a network in a linear, multi-drop configuration. These characteristics make such networks useful in industrial environments and similar applications.RS-485 enables the configuration of inexpensive local networks and multidrop communications links. It offers data transmission speeds of 35 Mbit/s up to 10 m and 100 kbit/s at 1200 m. 

RS-485 bus is the most popular communication method in industry. Compared with RS-232 bus, it is able to transfer information in further distance with lower cost. Establishing an “Internet of Things” by integrating RS-485 with Ethernet, which is the widely available in the world, in the hope that this method will coordinate all devices with low cost and high efficiency.

A USB to RS422/RS485 adapter is also available at KDRobotKit if you don't have Arduino at hand.
