A handheld or mountable air measuring device includes a sensor assembly with sensors that measure airspeed simultaneously in two directions that are perpendicular to each other. The
Something has changed Allows users to record changes in a room, or usage of a room, that they expect might affect the air quality longer-term, e.g. the addition of an air cleaner or a change in the number/operation of windows ✓ Measuring CO2 levels before and after exercise Encourages...
A project like this could be expanded to have a display or to use the WiFi capabilities of the ESP32 to create a remote or IoT device.ConclusionMeasuring and identifying sources of air pollution is the first step in making your air more breathable. The sensors presented here can assist you...
The angle of the prism was measured using a Zeiss Prismo Coordinate Measuring Machine (CMM). The accuracy of the CMM measurement is calculated from the CMM specification to be 0.5 µm36. The prism intended for liquid refractive index measurements was not ideal for air measurements, and while ...
This module output an analog signal representing the density of PM2.5 in the air. The sensitivity is 1V±15%/(100µg/m³), which is pretty good for air quality checking. A fan is integrated into this module as part of the Virtual Impactor design. When measuring the dust amount, thi...
