Wind Sensor Anemometer for Arduino, Measure Wind Speed and Temperature with Analog Output Anemometer

About this item

  • Perfect for medical devices, human breath detection, room occupancy detection, HVAC system monitoring, weather stations and more.
  • The hot wire technique excels at low to medium wind speed, and is the preferred technique for sensing indoor air movement
  • As an experimenters tool, the sensor is exquisitely sensitive, with a small puff of air being sensed at a distance of 18-24″.

Product Description

The Wind Sensor Rev. C is our low-cost anemometer with an analog output, that is designed for use with electronic projects. It is a thermal anemometer based on a traditional technique for measuring wind speed called the “hot-wire” technique. This involves heating an element to a constant temperature and then measuring the electrical power that is required to maintain the heated element at temperature as the wind changes. The wind velocity is proportional the heat (i.e. power) applied to the sensor. Hot wire anemometers are available in hand-held packages resembling multimeters, and tend to cost about $300 but this is the first small sensor suitable for electronic experiments. The hot wire technique excels at low to medium wind speed, and is the preferred technique for sensing indoor air movement, where the spinning cup anemometers typically seen on weather stations are ineffective. As an experimenters tool, the sensor is exquisitely sensitive, with a small puff of air being sensed at a distance of 18-24″. Possible applications include human breath detection, room occupancy detection, HVAC system monitoring, weather stations and many more.
