Selection Guide: How to Configure Equipment Based on Project Needs

1. Particulate accuracy and range: Standard municipal/construction sites select PM2.5 0–1000, PM10 0–2000 μg/m³; high-concentration industrial scenarios confirm range coverage.

2. Interface and protocol: RS485 Modbus RTU as mainstream; select 4–20mA for analog output needs.

3. Power supply and consumption: DC 12–24V low power (350 mW) suitable for solar; prioritize low-power design for remote sites.

4. Environmental adaptability: -20℃～+60℃, 0–99% RH covers most outdoor scenarios; extreme areas optional heating/dehumidification accessories.

5. Expandability: Reserve interfaces for later addition of Outside temperature sensor, noise, VOC, etc.

6. Budget and bulk: For projects 100+ units, directly negotiate tiered pricing and OEM solutions.

Integration Implementation Notes and Best Practices

• Installation location: Sensor air inlet 1.5–3 m above ground, avoid direct exposure to exhaust outlets or strong light sources; recommend adding rain cover.

• Electromagnetic compatibility: Use shielded cable + surge protector, RS485 bus length<1200 m, add terminating resistor.

• Data calibration: Compare with reference instrument after initial deployment, set offset in software; recommend on-site verification every 6–12 months.

• Power protection: Configure voltage stabilization module and lightning protection to prevent voltage fluctuations from damaging the laser.

• System fusion: At the platform level, implement linkage between PM values and meteorological parameters to generate AQI, pollution heatmaps, and alarm rules.
