February 2012:- The Deeter Group, market leaders in the design, development and manufacture of electronic sensors and control systems, has added a Wireless Modbus Gateway to its range of Wireless Sensor Network products. Any users of Modbus communication protocols will find the new Deeter Wireless Modbus Gateway is a simple and cost effective way to connect a Deeter Wireless Sensor network to a Modbus system to monitor physical or environmental conditions, such as liquid levels, temperature, humidity, vibration, pressure and proximity.

Deeter Modbus Gateway for Wireless Sensor System

The Deeter Wireless Modbus Gateway communicates with the Modbus network via a RS485 port in slave mode; it coordinates the wireless sensor network and manages data acquisition from the sensors using the IEEE 802.15.4 wireless protocol in the 2.4GHz ISM frequency band.

The Deeter Wireless System Modbus Gateway receives data from remote sensor nodes (either Senders or LVCS-RF) and makes this data available for polling by the Modbus Master. A Deeter Wireless Modbus Gateway may be installed as a component of a new control or measurement system or as an extension to an existing wired sensor system in order to add wireless connected sensors.

The Deeter Group’s comprehensive range of wireless sensors and network components may be used to remotely monitor temperature, pressure, flow, humidity, liquid level, float or proximity switches or any sensor connected to a 4-20mA control loop. Deeter wireless sensor networks are very versatile and can range from a simple single sensor measurement to complex multi sensor and multi-vendor systems with mixed sensor inputs and routers to extend wireless range and offer self-healing mesh networks.
