Temperature and RH Wireless Transmitter EMPRESA CERTIFICADA Introduction The RHT-Air is a wireless transmitter that when coupled with the AirGate-Modbus provides an excellent solution for wireless monitoring of temperature and relative humidity variables. Together, they combine the ease of configuration and data acquisition operation of the RHT-RS485-LCD, which connects directly to a Modbus RTU bus, with the versatility of the wire-free installation of LogBox-RHT. Through the IEEE 802.15.4 wireless interface, multiple RHT-Airs may talk to one or more AirGates, providing this way USB and RS485 communication paths to the main application. The RHT-Air uses high accurate sensors for measurements of the temperature, relative humidity and dew point. It also provides a LCD display for local viewing of the measurements while allowing reconfiguration of the transmitter parameters without having to run the configuration software on the computer. Features Operating limits: Sensor and probe: -20 to 80 °C, 0 to100 % RH Electronic circuit: 0 to+65 °C, 0 to 95 % RH Power supply Internal battery: Lithium ½ AA de 3,6 V Battery autonomy: typically1 ano External supply (optional): 10 to 35 Vdc, 70 mA max Wireless Protocol: IEEE 802.15.4 Configurator software DigiConfig for Windows® Accuracy: ±3 % RH from 20 to 80 % RH (at 25 °C) and ABS housing with IP65 protection, for wall mounting (WM model). Nylon probe Probe extension (DM model): Stainless steel 150 or 250 mm of length Dimensions: 70 x 60 x 35 mm Anatel certification Typical wireless range: Indoor: 100 meters In open field: 500 meters

info@novusautomation.com |www.novusautomation.com Application Topology Star Topology Long Range Application Operating on this topology, up to 246 Modbus slaves (wired or wireless) can be connected to the master through an AirGate-Modbus. Modbus masters can be connected both to the AirGate-Modbus RS485 and USB interfaces. Figure below shows a temperature and relative humidity monitoring system which is logged by a FieldLogger and is remotely supervised by the corporative network. It is possible to extend network ranges by using AirGateModbus as a repeater. Acting as a repeater, AirGateModbus...
