OVERVIEW
GebraBit ME2-CO is an Electrochemical Carbon Monoxide measurement module.
GebraBit ME2-CO module can operate with “3V3” or “5V” supply Voltages by Considered bottom jumper selector.
GebraBit ME2-CO module amplifies ME2-CO 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 an embedded potentiometer in the GebraBit ME2-CO module, when the Gas intensity goes above, or below the threshold, the “DO” pin and the “Dout” LED status will be changed.
ME2-CO is an electrochemical sensor 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 the electrochemical reaction of the target gas is in direct proportion with its concentration while following Faraday law. The concentration of the gas could be obtained by measuring the current value.
