PMS5003T PM2.5 particulate matter concentration sensor

Measurement Parameters

• Particulate Matter Measurement Range: 0.3 to 10 microns, with a counting efficiency of 50% for 0.3-micron particles and ≥98% for particles ≥0.5 microns.
• Particulate Matter Mass Concentration Resolution: 1 μg/m³. The effective range for PM2.5 mass concentration is 0–500 μg/m³, and the maximum range is ≥1000 μg/m³.
• Particulate Matter Mass Concentration Consistency: When PM2.5 concentration is 100–500 μg/m³, the error is within ±10%; within 0–100 μg/m³, the error is ≤±10 μg/m³.
• Temperature Measurement Range: 0–99°C, with a resolution of 0.1°C and accuracy of ±0.5°C.
• Humidity Measurement Range: 0–99%, with a resolution of 0.1% and accuracy of ±2%.

Electrical Parameters

• Operating Voltage: Typical value 5.0V, minimum 4.5V, maximum 5.5V.
• Operating Current: ≤100 mA, standby current ≤200 μA.
• Data Interface Level: Low level L<0.8V@3.3V, high level H>2.7V@3.3V.

Performance Parameters

• Response Time: Single response time <1 second, total response time ≤10 seconds.
• Mean Time Between Failures (MTBF): ≥3 years.

Physical Parameters

• Dimensions: 50×38×21 mm.
• Weight: No official data available, expected to be lightweight for easy integration and installation.

Output Parameters

• Output Modes:
  • Active Output: The default state after power-on, where serial data is actively sent to the host at intervals of 200–800 ms. The higher the particulate matter concentration in the air, the shorter the interval. Active output includes:
    • Stable Mode: When concentration changes are small, the same set of values is output three times, with an actual data update cycle of ~2 seconds.
    • Fast Mode: When concentration changes are large, new values are output each time, with an actual data update cycle of 200–800 ms.
  • Passive Output: No active data sending; data is read upon host request.
• Data Format: Output via a universal digital interface with default baud rate 9600 bps, no parity bit, 1 stop bit, and a protocol total length of 32 bytes.
