You can track and measure the quality of the air around you with this PMSA003I Air Quality Sensor, so you can breathe easily. This sensor is excellent for keeping track of air quality.
The PMSA003 is a general-purpose digital particle concentration sensor that outputs data in a digital interface form and can be used to measure the mass and number of suspended particles in the air per unit volume. To give precise and timely concentration data, the sensors can be integrated into a range of environmental devices that measure suspended particulate matter in the atmosphere.
