GasLab AlphaSense CO-AF Carbon Monoxide Sensor AP-0005

The AlphaSense CO-AF Carbon Monoxide Sensor provides an accurate and reliable way to measure up to 5,000 ppm CO by volume. The smart board and development kit converts the sensor’s analog output current to a voltage that is measured by a high-resolution analog to digital converter. The digital voltage is corrected and compensated for temperature and pressure by a micro-controller to produce an accurate gas concentration measured in ppm (parts per million). This can be read as serial UART output or can be logged in internal memory for later retrieval. In addition the board makes it easy to apply zero or span calibration. Features Excellent response time to changes in CO levels Low sensitivity to temperature changes Easy integration; compact & low power Models AP-0005 Sensor Only – for integration into high-volume OEM products. CM-31911 Development Kit – Easy to use, simply plug the EC Board into your PC via the included Serial UART to USB cable. Use our free GasLab® software to measure and graph carbon dioxide, barometric pressure, temperature, and % relative humidity. CM-31910 Smart EC Board – Same functionality as the development kit without USB cable or software.
