This is a DFRobot Gravity: PM2.5 Air Quality Sensor. DFrobot offers an advanced level of sensors at an affordable cost than any other competitor brand in the market, making them ideal for the one who wants to start some Projects through Different types of sensors. After finding Different types of sensors on market, we at Elecvora.in have determined that DFrobot is one of the good brands that offer a wide range of sensors at an Appropriate price. As the most basic part of life, the air is attracting more and more attention, for example, the most common PM2.5, PM1.0, PM10, etc. Keeping an eye on the quality of the air we breathe is becoming quite important. DFRobot brings you this Gravity: PM2.5 Air Quality Sensor that can measure particulate matter like PM2.5, PM1.0, PM10. With an easy-to-use Gravity interface, the air quality sensor works well with most main controllers. And we provide you with relevant sample codes to help you quickly build up air quality monitoring projects. Based on the principle of laser scattering, the Gravity: PM2.5 Air Quality Sensor employs a digital universal particle sensor that can continuously collect and calculate the number of suspended particles of different sizes in the air per unit volume, which is particle concentration distribution, and then convert to concentration and output via the I2C interface. The sensor can be embedded in various instruments and meters or environmental improvement equipment related to the concentration of suspended particulate matter in the air to provide timely and accurate concentration data. Gravity: PM2.5 Air Quality Sensor is typically suitable for smoking rooms, kitchens, hot springs, bathrooms, and other environments. So, after reading about this Gravity: PM2.5 Air Quality Sensor you might have some questions stuck in your mind that, How does this Sensor work? Well, This sensor works on the principle of laser scattering, which entails irradiating suspended particles in the air with a laser to cause scattering, collecting the scattered light at a specific angle, and calculating the intensity of the scattered light over time. Furthermore, the microprocessor calculates the equivalent particle size of the particles and the number of particles of various particle sizes per unit volume using the MIE theory algorithm.
