How to connect to microcontrollerThe sensor has three pins +5V, A.Out and GND. Give regulated +5V to sensor and it will outputanalog voltage in the range of 0V to 5V range. This output can be read in microcontroller throughinternal or external ADC(Analog to Digital Conversion) and process it for further actions.MicrocontrollerADC Read
Testing on Celing FanThe first moving object you find in all homes is obvoiusly celing fan so we tested the sensor againstfan from off to fast.Fan is OFF, See the steady outputFan is started at slow speed, You can see motion of rotating blades being detected.Fan at High Speed, The output is changing rapidly as blades rotates fast.3Sunrom Technologies Your Source for Embedded Systems Visit us at www.sunrom.com
