Sense both barometric air pressure as well as ambient temperature with this sensor. Go up in the air, climb a mountain: our software allows you to calculate your altitude using the sensor data. A digital I²C sensor, that outputs calibrated, high resolution, low-noise signals.

Application examples

Combine the Air2D sensor with a Humid and Light to create a full-blown home climate control system. Add Switches to control water valves.

Technical specifications

Software support

23 Jul 2019: Air2D v1.10 for MacOS and Windows from source code in Max. For multiple sensors or sensor outputs, run multiple instances of the application, each started in its own folder. Requires a digitizer with firmware v7.3 or higher. Use together with Connect (MacOS / Windows).

17 Jun 2017: Air2D v1.00 for MacOS and Windows from source code in Max. For multiple sensors or sensor outputs, run multiple instances of the application, each started in its own folder. Requires a digitizer with firmware v7.3 or higher. Use together with Connect (MacOS / Windows).

Application notes

Make sure the sensor is plugged into the digitizer with the red wire connected to power. Reversing the plug may cause damage to the sensor.

Requires a digitizer with digital (I²C) ports, eg. USB-microDig or WiDig with firmware v7.3 or higher.

The default I²C address is 119 (0x77). Both I²C lines have 2.2 kOhm pull-up resistors.

Our software enables you to use most features of this sensor.

See the Air2D function description in the firmware documentation for more details about the various methods available in host and standalone mode.

For more technical specs, and to find out how to access the sensor data in detail, please consult this datasheet.

To extend the cable, use ExtendCableD-01 and/or ExtendCableD-10.
