Calibrating the C2H5OH Gas Sensor Module !!!!!!!!!!!!!!!!! Please Help me !!!!!!!!!
I read the instructions on the pdf for gas calibration and i'm still having difficulty calibrating this. This is my first time using microcontrollers. I have no experience with this. Can i use the sample program provided for the Co 2 sensor to calibrate the alcohol gas sensor. The steps provided for calibration are mainly for the Co2 sensor. http://www.parallax.com/Portals/0/Downloads/docs/prod/sens/27904_27930-1-2-GasSensor-v2.2.pdf
if the steps are the same how do i read the voltage across tp3 and tp4. should i use a multimeter that. If anyone has a step by step instructions or video on this. It also says to calibrate the sensor to detect 0.4mg/L. is there a way i can make it read values on a lcd display like this guy did on a multimeter. the guy i'm talking about is on youtube. the link is below
