keyestudio GP2Y1014AU PM2.5 Detection Dust Sensor Module For Arduino For Air Condition

The Keyestudio GP2Y1014AU PM2.5 Dust Sensor Module is an optical air quality sensor designed to detect very fine airborne particles. It is ideal for students, hobbyists, and makers looking to build Arduino-based air purifiers or environmental monitoring systems.

Optical particle detection

The module utilizes an onboard Sharp GP2Y1014AU sensor containing an infrared LED and a photoelectric transistor. By measuring the light reflected by dust, it can detect very fine particles larger than 0.8 micrometres in diameter, including cigarette smoke.

Linear analog voltage output

The sensor provides an analog voltage output that is linear with dust density, offering a sensitivity of 0.5V per 0.1mg/m3. This makes it straightforward to interface with analog-to-digital converters on microcontrollers.

Low power consumption

Operating with a typical current of 11mA and a maximum of 20mA, this sensor is highly energy-efficient. It operates on a supply voltage between 5V and 7V DC, making it suitable for low-power projects.

Robust environmental specifications

Designed to operate in temperatures ranging from -10 to 65 degrees Celsius, this module has a storage temperature range of -20 to 80 degrees Celsius. It features a typical clean air voltage of 0.9V and an expected lifetime of five years.

Compact physical dimensions

Measuring 62mm by 36mm by 20mm, the compact footprint allows for easy integration into custom enclosures and air conditioning units. This makes it a versatile choice for space-constrained DIY projects.
