product reviewThis one-of-a-kind sensor provides an excellent alternative to many sensors involving air quality detection, because it includes functions and attributes such as:
1. The high sensitivity towards various dust conditions, which is followed by its quick response time for the sensor's serial communication to a microcontroller. 2. The technology involved in this sensor, as this sensor includes: an Infrared LED, a set of lens, a photodiode detector and electromagnetic shielding. 3. The compactness and size of this sensor, especially for its dust sensing function. This sensor could easily fit into an air quality monitor box or any other DIY casing. 4. The simple software involved with coding this sensor as it is simple, with sampling included, to convert raw values into a specific unit of measurement (pcs/0.01cf). 5. The uncomplicated hardware framework to prepare this sensor for use, because of the three wires to a microcontroller (VCC, GND and Signal). This is definitely a starting sensor for a beginner. 6. The many resources involved when purchasing this sensor, as the source code and any additional information (Precautions, Project Ideas, Readings vs Time, etc.) are all given in the Wiki page. |
