PM2.5 and PM10 Particle Sensor Analog Front-End for Air Quality Monitoring Reference Design
Description
TIDA-00378 provides an analog front-end for measuring PM2.5 and PM10 particle matter. The reference design detects light scattered by particles suspended in air. A sample software algorithm is provided to convert the analog output of the design into a particle size and concentration measurement. Test result data for cigarette smoke: Arizona dust and mulberry pollen is provided along with all software and hardware design files.
Features
- Analog front-end design for PM2.5 (Dust measurement range from 340 x 103 to 991 x 103 pcs/ft3 (12 to 35 pcs/cm3) at 75% accuracyZero-volt bias to minimize photodetector noise and stabilize performance over temperatureInstrumentation amplifier topology to reject external noise sourcesLow noise: low-input bias current and low offset op-amps with rail-to-rail output to maintain high SNR and increase output dynamic rangeTested against Arizona dust: mulberry pollen and cigarette smoke using adapted ANSI/AHAM AC-1-2013 test standardFull algorithm source code for PM2.5 and PM10 calculation for customization and porting
