Gravity: Laser PM2.5 Air Quality Sensor For Arduino

The PM2.5 laser dust sensor is a digital all - purpose particle concentration sensor. It accurately measures the number of suspended particulate matter in a unit volume of air, with a size ranging from 0.3 to 10 microns, and outputs both particulate matter concentration and per - particle quality data via a digital interface. This sensor can be easily embedded in various air - related environmental instruments, offering real - time and precise concentration data. Specifications include a voltage range of 4.95 - 5.05V, a maximum current of 120mA, and a measuring pm diameter of 0.3 - 1.0/1.0 - 2.5/2.5 - 10 (um). It has a measuring pm range of 0 - 1000 ug/m3, a standby current of ≤200 uA, and a response time of ≤10 s. The sensor operates in a temperature range of - 20 to 50°C and a humidity range of 0 - 99% RH. It has a maximum size of 46 * 35 * 20mm (1.82 x 1.38 x 0.79 inches) and an MTBF of >= 5 years. Documents include a wiki and a library. The shipping list contains one PM2.5 laser dust sensor, one PM2.5 sensor adapter, and one sensor adapter cable.

Using this PM2.5 air quality sensor is easy. First, connect the sensor to your Arduino board using the provided adapter and cable. Make sure the voltage supply is within the 4.95 - 5.05V range. Once connected, the sensor will start measuring the air quality and sending data to your Arduino. When using the sensor, keep it away from direct sunlight and extreme heat or cold. The operating temperature range is - 20 to 50°C and humidity range is 0 - 99% RH. Don't expose it to harsh chemicals or excessive moisture. For maintenance, check the connections regularly to ensure they are secure. The sensor has a long service life with an MTBF of >= 5 years, but if you notice any abnormal readings, check the power supply and connections first.
