What exactly is a PM10 Sensor?
1.In-depth Explanation of PM10 and PM10 Sensor
1.1Definition of PM10
PM10 sensor denotes particulate matter with a diameter of 10 micrometers or smaller. People commonly know these particles as inhalable dust or particles. Their small size lets them stay in the air.
People can breathe them into the human lungs. This may cause health problems like respiratory and heart diseases. PM10 originates from a variety of sources:
Natural Origins: Sandstorms, volcanic eruptions, and similar events.Human Activities: Emissions from industries, vehicle exhaust, road dust, farming activities, and more.
1.2 Explanation of a PM10 Sensor
A PM10 sensor is an instrument designed to assess the levels of PM10 particles present in the air. It can track PM10 levels in real-time, offering data that aids in environmental management and health safeguarding
2. PM10 sensors generally operate based on one of these principles:
2.1. Light Scattering Principle:
– Principle: The sensor projects a laser or LED light, and as airborne particles traverse this light beam, they cause scattering. The angle and strength of the scattered light reveal the size and concentration of the particles.
– Advantages: Offers high sensitivity, rapid response, and a wide measurement range.
– Disadvantages: Requires controlled environmental conditions, and optical components need regular maintenance and cleaning.
2.2. Beta Ray Absorption Principle:
– Principle: This technique assesses how much PM10 particles absorb beta rays, which is directly related to their concentration.
– Advantages: Provides precise measurements and is ideal for long-term monitoring.
– Drawbacks: Entails greater equipment expenses and more complex operations.
2.3. Gravimetric Approach:
– Principle: A defined volume of air is sampled, and the particles’ weight is measured to determine their concentration.
Pros: Precise measurements, ideal for lab environments or high-accuracy monitoring.
– Cons: Bulky size, unsuitable for portable gadgets.
