- US company GE SM-PWM-01A is a detection of dust in the air concentration of dust sensor using optical methods. There is a dust sensor and an infrared diode image sensors , their optical axes intersect , the intersection area is proportional to the air flow with dust when the dust crosses the optical axis by the infrared light reflected , the reflected light intensity and dust concentration . The image sensor detects infrared light reflected infrared diode dust emitted by the signal conditioning circuit , the output pulse width modulated signal , and dust (PWM) reaction .
GE 's SM-PWM-01A as the dust sensor can detect the particle size of the particulate matter of cigarette , large particles can be detected indoor dust, etc. , through the output of two different pulse width modulation (PWM) signal to distinguish between the different concentrations of dust particles .
- SM-PWM-01A dust sensor Benefits Features
- Compact, light weight (W59x H45x D20 mm, ~ 35g)
- PWM (pulse width modulation) output ( Low pulse output )
