PM2.5 Air Quality Kit (PMSA003 + SHT20)

The PM2.5 Air Quality Kit is an affordable yet high - performance pollution sensor. It integrates PMSA003 and SHT20, allowing you to measure air quality, temperature, and humidity all in one device. Academic and government environmental organizations have debated its accuracy and its role in environmental regulation and air quality trend reporting. With the M5Stack product series, it's easy to deploy measurement nodes across the city and build a complete ecosystem from regulation to citizen awareness. The PMSA003 uses the laser scattering principle for precise measurement, offers digital output via standard UART communication, has zero error alarm rate, real - time response, and continuous acquisition. It can detect particles as small as 0.3 µm, has high antijamming capability, and a tiny 12 - mm body. The SHT20 is a fully calibrated humidity and temperature sensor with digital output via I2C interface, low power consumption, and excellent long - term stability. The product features DC 5V, compatibility with M5stack stackable and extension system, M5Core pedestal, proto board, and USB Type - c port. The package includes 1x PM2.5 base, 1x M5Stack Basic, 1x M5Core pedestal, 1x Type - c cable, and 2x M3 screw. Examples are available for Arduino, and there are related forum links and schematics for PM2.5. Datasheets for SHT20 and PMSA003 are also provided.

Using this PM2.5 Air Quality Kit is easy. First, connect the Type - c cable to power it up. The kit is compatible with the M5stack stackable and extension system, so you can easily integrate it into your existing setup. Once powered, it will start measuring air quality, temperature, and humidity right away. For programming, you can use Arduino as an example. When using the kit, avoid exposing it to extreme temperatures or high - humidity environments for long periods. Also, keep it away from strong electromagnetic fields as it might affect the sensors' accuracy. To maintain the kit, clean the sensors gently with a soft, dry cloth. Check the connections regularly to make sure they are secure. If you have any questions, you can visit the related forum for more information.
