CO2 Gas Sensor User Manual – Vernier

The CO 2 Gas Sensor refreshes its reading every second, but typical changes in experiments are so gradual that the recommended sampling rate is 4 seconds per sample or slower. Gas must diffuse through the holes in the sensor tube before the sensor detects any changes in concentration. Because diffusion of gases is a slow process, there can be delays in the readings. To collect data in a ...
