Description

The TIDA-00378 TI Design provides an analog front-end solution for measuring PM2.5 and PM10 particle matter. The design detects the 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 (<2.5µm) and PM10 (<10µm) particle detection and count
  • Dust measurement range from 340 x 103 to 991 x 103 pcs/ft3 (12 to 35 pcs/cm3) at 75% accuracy
  • Zero-volt bias to minimize photodetector noise and stabilize performance over temperature
  • Instrumentation amplifier topology to reject external noise sources
  • Low noise, low input bias current, low offset op-amps with rail-to-rail output to maintain high SNR and increase output dynamic range
  • Tested against Arizona dust, mulberry pollen, and cigarette smoke using adapted ANSI/AHAM AC-1-2013 test standard
  • Full algorithm source code for PM2.5 and PM10 calculation for customization and porting
