RHT-Air
WIRELESS EQUIPMENT FOR TEMPERATURE AND HUMIDITY – INSTRUCTIONS MANUAL V1.0x A
1 INTRODUCTION
RHT-Air comes with a high precision and stability sensor to measure both
temperature and relative humidity. Because it operates with a
microprocessor, it can be fully configured through its USB and IEEE 802.15.4
interfaces, using Modbus RTU commands. The software DigiConfig enables
for all the equipment’s resources to be configured.
RHT-Air can be configured to display the temperature and Relative Humidity
measured or even, the temperature and the Dew Point
RHT-Air should be connected (via wireless) to an AirGate-Modbus so that
its registers can be read whenever it is in operation.
1.1 IDENTIFICATION
The following elements appear in the front part of the equipment:
Fig. 1 – RHT-Air main screen
Communication Indicator (COM): It signals that the device is receiving data
from the Modbus network.
Button (Programming): This button is used to configure the Modbus
address, the Update Interval and screen changes.
Temperature: Room temperature measured by the equipment.
Relative Humidity: Relative Humidity measurement.
