AVTECH Room Alert Digital Temperature & Humidity Sensor
The AVTECH Room Alert Digital Temperature & Humidity Sensor is designed for Room Alert environmental monitoring systems. It allows real-time monitoring of temperature, relative humidity, heat index and dew point in technical rooms, small data centers, telecom cabinets, offices, warehouses and other spaces sensitive to environmental conditions.
This sensor connects directly to a compatible Room Alert monitor using an RJ-11 cable, helping expand environmental monitoring without replacing the main monitoring unit.
Available cable lengths
This sensor is available in three RJ-11 cable lengths: 25 ft / 7.62 m, 50 ft / 15.24 m and 100 ft / 30.48 m. The correct variant should be selected according to the distance between the Room Alert monitor and the location where temperature and humidity need to be measured.
Essential expansion for humidity monitoring
When used with a compatible Room Alert monitor, this sensor adds humidity and dew point monitoring, making the system more complete for environments where both temperature and humidity control are required.
- Real-time digital temperature monitoring.
- Relative humidity monitoring from 5% to 95%, non-condensing.
- Supports heat index and dew point readings.
- Plug & Play connection via RJ-11 cable.
- Available with 25 ft, 50 ft or 100 ft cable length.
- Compatible with several Room Alert monitors.
- Ideal for technical rooms, racks, warehouses, offices and spaces with sensitive equipment.
Recommended use
This sensor must be used together with a compatible Room Alert monitor. For a cost-effective alternative to older environmental monitoring systems, it can be combined with a Room Alert 3S monitor to add temperature, humidity and dew point monitoring.
