Pollution is a serious problem in our world, and unfortunately shows very little sign of slowing down as we our society continues to expand and develop in a wide range of different ways. However, what may be the biggest problem with the current scenario we face is the fact that we can’t always see the pollution that affects us most. And while we can certainly see litter on our landscapes and rubbish in our rivers, we can’t always see air pollution, and this can be quite dangerous depending on the levels of pollution in the air – which we of course can’t recognise without the use of clever Sensors.

This is what makes the Analog Infrared CO2 Sensor such a great choice for Healthy Makers who want to breathe oxygen-rich air keep their brains pumping at maximum capabilities, as it allows us to measure factors that lie beyond what our eyes are capable of seeing, enabling us to carefully control our air quality with precision – leading to a healthier, happier environment for us to thrive in.

This clever little carbon dioxide sensor offers an impressively high precision, and is capable of measuring between 0 and 5000 parts per million of carbon dioxide in an environment via the use of non-dispersive infrared technology. This means you can utilise this sensor to ensure perfect air quality for a range of different applications, as well as just for health reasons, so that you, your family and even your pets can enjoy the healthiest breathing-air possible.

Typical Applications for this High Sensitivity Analog Infrared CO2 Sensor:

With such a high level of sensitivity, this Analog Infrared CO2 Sensor is most commonly used for breathing-air quality control, as well as similar types of applications requiring the lowest carbon dioxide concentration as possible. This is because the sensor’s high level of accuracy only allows for measurements up to 5000 parts per million, which is actually quite low compared to what you would find in some environments, and this unfortunately means that it’s not ideal for building indoor gardening setups requiring high levels of CO2. However, for any and all applications involving extremely low levels of carbon dioxide – or at least striving to achieve such a level – this sensor’s extreme sensitivity and high precision is perfect.
