Gravity: Analog Infrared CO2 Sensor For Arduino (0~5000 ppm)
Web, l is the pathlength (sensor cavity depth, and c is the concentration. Because l and ε are fixed, measuring the light intensity before and after the sample allows a measurement of the concentration. NDIR SENSOR DESIGN. Figure 3 shows a top view of the overall NDIR sensor design. The gas sample diffuses in through a metal frit in the top ... WebThe CO2 sensor chosen here is an infrared NDIR CO2 sensor made by Gravity. Several other models exist on the market, although most are more expensive than this one. This particular model provides an analog output with a tension varying from 0 to 2V. This output is connected to pin A2 on the board. bus provincetown to wellfleet
