PLANTOWER PMSA003-A Gas sensor UART is a kind of digital and universal particle concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles, and output them in the form of digital interface. PLANTOWER PMSA003-A Gas sensor UART sensor can be inserted into variable instruments related to the concentration of suspended particles in the air or other environmental improvement equipments to provide correct concentration data in time.
Features:
- High Sensitivity:Minimum distinguishable particle diameter: 0.3 µm.
- Zero False Alarm Rate:Reliable detection with no false alerts.
- Real-Time Data Output:Immediate response to changes in particle concentration.
- Accuracy:Provides correct and precise measurements.
- Advanced Anti-Interference Design:Six-sided shielding for enhanced performance in noisy environments.
- Flexible Airflow Design:Customizable air inlet and outlet directions to fit various installation needs.
- Measurement Range:Capable of detecting particles from 0.3 to 10 µm.
- Counting Efficiency:50% efficiency at 0.3 µm and 98% at ≥0.5 µm.
- PM2.5 Measurement:Effective range: 0-500 µg/m³; maximum range ≥1000 µg/m³.
- Quick Response Time:Single response time of <1 second; total response time ≤10 seconds.
