AirQ 101-EXT is a temperature sensor with same features of AirQ 101 model, but equipped of a external probe connector. Useful for monitoring temperature in a measurement range greater than AirQ 101 range.


1 Wireless:  no wiring, no change for existing installation. Just put it wherever you need.

2 External probe: thanks to external probe, the measurement range is greater.

3 Web controlled: thanks to web oriented AirQ Networks architecture, all AirQ 101-EXT sensors are web accessibile.

4 Battery powered: AirQ 101-EXT is a battery powered wireless sensor. The battery is user replaceable.

5 Mobile ready: AirQ Networks web platform it’s fully compatibile with iPhone, Andorid and Windows Mobile devices.

6 SMS (text message) and E-Mail alarms: thanks AirQ Rule System it’s possibile to define alarms that start when a user defined event occurs. Alarms can be also sent by SMS (text message) and E-Mail without using additional device.

7 No programming required: AirQ 101-EXT sensors works just out of the box, without any particular technical skills.

8 Flexible and powerful rule system: AirQ 101-EXT sensors can be used with the flexible AirQ Networks graphical rule system. Just design your application and put it to work: they do all dirty work!

9 Installation: Just leave the sensor anywhere you want: no installation is needed!

What is the maximum distance between sensors and control units or range extenders?

There isn’t a fixed rule that states what is the maximum distance between sensors and control units. Maximum distance is related to the environment where sensors are placed. In closed spaces a distance higher then 50 meters is typically achievable. In open spaces maximum distance can be extended up to 500 meters and more. Using range extender the operative range can be extended as needed. At the end, some noisy devices (motors, high inductive devices, other wireless devices operating on 433Mhz) can reduce operative distance of sensors. As rule of thumb, we suggest to test the effective position of sensors and control units before to do final installation. It’s really common to obtain better RF performances simply changing devices position of some centimeters.

How often sensors send data to control units?

AirQ 1XX sensors are designed to reduce battery consumption and give the best accuracy of measurement in the same time. All AirQ 1XX sensors are programmed to work in a double mode:

  • If temperature is stable, sensor sends data to control unit every 8 minutes. This is important both to give current detected temperature and to signal sensor activity (if control unit doesn’t receive new data in 15 minutes, sensor is considered as ‘unlinked’ – see wiki for further information).
  • If temperature change more then ±0.5°C, sensor will send data in about 4 minutes.

If you need an higher detection frequency, please contact AirQ Networks customer service.

How to install?

Every AirQ 1XX can be installed directly where needed as long as operating temperature is respected. For example, an AirQ 100 temperature sensor can be placed inside a frozen room if temperature is higher or equal then -30°C up to +85°C. Using enclosures with flange, sensor can be applied to walls or fixed surfaces using screws.

What's the better external probe for me?

Choose the probe depending of your measurement requirements. For example, a PT100 external probe is used where high measurement is mandatory, or the K thermocouple is used when measurement range spread is most important.

During purchase we will help you to choose the product more suitable

Are sensors calibrated? Is it possible to obtain calibration certificate?
All AirQ Networks sensor are calibrated by AirQ Networks and they guarantee declared precision for at least 1 year.
Moreover, AirQ Networks can provide calibration certificate if needed. Please contact customer service.
