RHT Air+ Wireless Humidity & Temperature Data Logger Sensor
| Humidity Measurement Range | 0-100 %RH (typical) (10-90 %RH) | Temperature Measurement Range | -10...+70 ºC |
|---|---|---|---|
| Humidity Accuracy | ±1.5 %RH | Temperature Accuracy | ±0.2 ºC |
| Resolution | 0.1 %RH | Temperature Resolution | 0.1 ºC |
| Data Logger Memory | 15,000 measurement records | Logging Interval | Adjustable from 1 minute or longer |
| Wireless Communication Technology | LoRa | Transfer of Logged Data | Yes. If the wireless connection is interrupted and later restored, any data that could not be transmitted is automatically sent in bulk to the receiver. (The receiver also has its own internal memory.) |
| Wireless Data Transmission Interval | Adjustable from 1 minute or longer (Recommended intervals: 5, 10 or 15 minutes) |
Display | 2-line LCD (also displays signal strength and battery status) |
| Power Supply |
Internal Battery: 2 x AA 3.6 VDC (replaceable) External Power Supply: Via USB-C input (When external power is available, the battery is not used; in the event of a power failure, the device automatically switches to battery power.) (The device can also operate on battery power only.) |
Estimated Battery Life | Approximately 2 years (with a 15-minute interval) |
| Mounting | Screw Mounting or Magnetic Mounting (magnetic back) | Protection Rating | IP65 (device), IP40 (probe) |

Configuration and Data Analysis with Free NXperience Software
With the free NXperience software provided by NOVUS Automation, the RHT Air+ sensors and AirGate Air+ gateway unit can be easily configured. Measurement and logging intervals, alarm levels, wireless connection settings, network settings, Modbus TCP/IP settings and MQTT settings can all be configured through the software.
Humidity and temperature data stored in the memory of the devices can be downloaded to a computer using NXperience, displayed in graphs and tables, analyzed and reported. This allows historical measurement records to be evaluated separately while the system continues transferring data to SCADA or IoT platforms.
