ZP07-MP503-4 Air Pollution Sensor

High-Sensitivity Flat-Surfaced Semiconductor Element: Employs an advanced MP503 planar semiconductor gas sensor element for fast, reliable detection of airborne pollutants.

Broad Airborne Organic & Toxic Gas Coverage: Highly sensitive to volatile organic compounds (VOCs), formaldehyde, benzene, carbon monoxide (CO), ammonia (NH₃), alcohol, and smoke.

Pre-Calibrated Signal Output Modes: Provides pre-calibrated output levels (including PWM, 0–3V analog voltage, or UART TTL levels) for direct microcontroller processing without complex calibration.

Low Operating Power Consumption: Operates on low heating power consumption, ideal for continuous indoor air quality sampling and energy-conscious IoT devices.

Automatic Sensitivity Calibration: Built-in internal processing compensates for ambient baseline shifts to maintain consistent, reliable detection over prolonged use.

Housing Material: Flame-retardant FR-4 PCB breakout board with protective metal mesh housing and 4-pin interface header.

Technical Specifications:

Sensor Element: MP503 Semiconductor Air Quality Transducer.

Operating Voltage: 5.0V ± 0.2V DC.

Warm-Up Time: ≤3 minutes.

Detectable Gases: Formaldehyde, VOCs, Benzene, Carbon Monoxide, Smoke, Alcohol.

Signal Output: Analog Voltage / PWM Output / UART TTL (depending on mode configuration).

Board Color: Green PCB with Silver Metal Sensor Cap.

Usage Advice: Connect VCC (5V), GND, and signal output pins to your microcontroller; allow the module to pre-heat for up to 3 minutes after power-on to stabilize base resistance before logging readings.

Maintenance: Keep the metal sensor cap clean and free of oil, grease, and direct water condensation; do not expose the element to high concentrations of silicone vapors or corrosive gases.

Essential Compact Air Quality Diagnostic Transducer: Position as a versatile, low-cost air pollution sensor for smart air purifiers, fresh-air ventilation fans, automatic range hoods, and IoT air quality monitors.

Highlight Pre-Calibrated Multi-Gas Detection: Emphasize how its integrated pre-calibrated output allows quick, plug-and-play setup for detecting hazardous VOCs and formaldehyde without needing expensive lab calibration tools.

Recommended Cross-Sell Add-ons: Pair with MQ-135 Air Quality Gas Sensor, CCS811 Air Quality Sensor, ENS160+AHT21 Carbon Dioxide, Air Quality, Temperature And Humidity Sensor CO2 eCO2 TVOC, and ESD antistatic mat 50x40CM PCB Welding Mat.
