N H Moon Posted July 17, 2016 Report Share Posted July 17, 2016 I am planning to design & construct a hot wire anemometer. I am facing problem to find the required data. I search in the internet but couldn't get the data. How can i start my project & where i can get the information? Quote Link to comment Share on other sites More sharing options...
admin Posted July 17, 2016 Report Share Posted July 17, 2016 I have found a simple circuit diagram about hot wire anemometer. May be a good point to start. Look at the bottom of this page: http://newton.ex.ac.uk/teaching/CDHW/Sensors/ Also check this slides about the theory behind it: http://www.ara.bme.hu/oktatas/tantargy/NEPTUN/BMEGEATMW03/2012-2013-II/Presentation/Hot-Wire Anemometry.pdf Quote Link to comment Share on other sites More sharing options...
Externet Posted July 19, 2016 Report Share Posted July 19, 2016 If you end giving up on the design and construction, hot wire air flow meters are dumped daily by the many hundreds. You can obtain them for few $ at a car boneyard. They are called MAF sensors and in many flavors and sizes. There is at least two types; one outputs a frequency and another voltage. Discern which with an oscilloscope. They are powered usually by 5V, the 3 terminals are +, -, out. They look like ----> https://duckduckgo.com/?q=air+mass+sensor&t=canonical&iax=1&ia=images Get a wiring pigtail with its mating connector.
