OVERVIEW
GebraBit ME2-O2 is an Electrochemical Oxygen measuremen module.
GebraBit ME2-O2 module can operate with “3V3” or “5V” supply Voltages by Considered bottom jumper selector.
GebraBit ME2- O2 module amplifies ME2- O2 sensor output by an integrated op-amp circuit for better analysis and interpretation and provides it on the module “AO” pin. For reading CO data, just connect the analog “AO” pin to MCU ADC and go on.
The Gas intensity threshold is adjustable by a potentiometer embedded in the GebraBit ME2- O2 module, when the Gas intensity goes above, or below the threshold, the “DO” pin and the “Dout” LED status will be changed.
ME2-O2 is a electrochemical sensor to detect gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current.
