As per the above post by dansole and the link he posted (ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier [STEMMA QT / Qwiic] : ID 1085 : Adafruit Industries, Unique & fun DIY electronics and kits), it would be better to use that 16 bit ADC board for Analog Voltage Output. Just searched for it, you can find it much cheaper from here (https://www.ebay.com/itm/312503053984) instead of adafruit.Yes I think calibration would be required as per the item description in the link (Winsen ZE11 C2H4 High-performance Gas Detect Electrochemical Module for Arduino | eBay). It would be better if you ask dansole on the calibration part since he would be more adept to answer than me. Or else you could ask for the code he had written (if he still has it?). You could use his calibration code itself.
Hi dansole, kindly provide guidelines and what is your opinion?
