Description
The RHT-AIR is a fully wireless solution for measuring temperature and humidity over long distances, allowing the configuration and reading of the parameters through the wireless network up to 1 km, bringing practicality and efficiency to the application. Units can be battery powered, or via 12-30vDC for continuous operation. Data can be collected by a central AirGate Modbus unit and relayed to a Fieldlogger or AirGate unit for connection to a remote Web server.
Features
- Long Range Wireless Transmission, up to 1Km
- Independent Wireless Network
- Large Battery Life (Up to 2 Years @ 10 min interval
- Easy Network Scalability
- Noise Immunity

RHT-Air has an IEEE 802.15.4 wireless communication to connect to AirGate Modbus that has its firmware updated to a version more recent than V1.23. The first RHT-Air configuration must be performed via the USB interface through the DigiConfig software. In it, the necessary parameters for communication with AirGate network should be set. After the first time it is configured and matched with a AirGate-Modbus, RHT-Air will operate as a Modbus RTU slave. From this moment on, all its resources can be accessed by reading its registers anywhere in any Modbus RTU network.
