May 09, 2015· VRL = map (sensorValue, 0, 1023, 0, 5000); Once you have the voltage, you can compute the resistance of the sensor using the formula. Rs= (Vc/VRL1)×RL. with Vc the circuit voltage (5V), VRL the voltage over the load resistor, and RL the resistance of the load resistor in Ohms. The tricky part is to convert this to a concentration in ppm CH4.
