Dust sensor DN7C3CA007
Sharp's DN7C3CA007 is a dust sensor module that uses the air pressure of the fan to detect and separate PM2.5 or smaller particles. The specially developed shunt (virtual impactor) can reduce the size of the sensor, so high-precision measurement can be achieved.
Features
PM2.5 particles will be separated by the fan-driven virtual impactor cover. The integrated dust sensor has high sensitivity (less than 17ug/m3), and will produce different output voltages according to the dust concentration.
application
Indoor Air Quality Measurement (IOQ)
air conditioning
air filter
Environmental monitoring
Sharp said that the smallest sensor is 53mm*40mm*51mm. Due to the use of a high-sensitivity photoelectric sensor in the module, it can measure the PM2.5 in the air in just 10 seconds. The concentration and measurement speed are the fastest in the industry. Due to its small size, DN7C3JA007 can be easily incorporated into air purifiers and other products.
At present, PM2.5 detection instruments use several methods to shunt PM2.5 and other suspended particles, and then use a light sensor to measure. The structure of instruments commonly used in the industry is complex, requires regular maintenance, and the instruments themselves are expensive. However, the DN7C3JA007 module combines a shunt and a high-precision sensor using LEDs and is miniaturized, which can make the instrument basically maintenance-free and the cost will be reduced.
Working principle: After blowing air into the air inlet, PM2.5 with lower inertia will float on the halfway, which can be checked with a sensor
