Frequently Asked Questions

What is the output signal of the Winsen MED-2CO sensor?

The MED-2CO provides an analog current output signal. Its sensitivity is (200 ± 65) nA per ppm of carbon monoxide. This current signal requires an external circuit, typically a precision load resistor, to convert it into a measurable voltage for a microcontroller's ADC or a dedicated transimpedance amplifier.

What is the typical response time of this CO sensor?

The sensor has a fast response time, reaching 90% of its final output value (T90) in less than 30 seconds upon exposure to a step change in carbon monoxide concentration. This makes it suitable for applications requiring timely detection and alarm triggering for safety.

How do I power and interface the MED-2CO with an Arduino?

The sensor operates on low power, but the exact supply voltage should be confirmed from its datasheet. Typically, electrochemical sensors require a stable bias voltage. The current output pin connects to a transimpedance amplifier circuit, whose voltage output can then be read by an Arduino analog input pin for ppm calculation.
