In this post, we will make a temperature based fan control using arduino and lm35. LM35 is temperature sensor, whose output is analog (linear). Arduino uno has six channle of adc (A0-A5)
and adc is of 10-bit
Stuff required:
 |
| Circuit Diagram |
Resolution = Vref/((2^n)-1) = 5000 (in mV)/1023 [2^10-1]
that comes out to be, 4.887 millivolts
For temperature calculation, Voltage (in millivolts)/10 [Sensitivity is 10mV per degree Celsius]
