JK4A-5L239-CA | Genuine Ford® Particulate Metter Sensor

Detects harmful particles like PM2.5 and PM10 that can:

• Worsen asthma or respiratory issues

• Cause cardiovascular problems

• Lead to long-term health risks

Used in homes, schools, offices, and hospitals to ensure safe breathing air

Allows air purifiers to automatically adjust fan speed based on real-time air quality

Improves energy efficiency and purification effectiveness

Tracks air pollution levels in cities, industrial zones, or construction sites

Supports regulatory compliance and public health alerts

Integrated into smart thermostats or air quality monitors

Enables data logging, mobile alerts, and automation (e.g., turn on fan if PM2.5 is high)

Detects particle emissions from machinery, production lines, or chemical processes

Ensures worker safety and protects sensitive equipment

Monitors air inside vehicles (especially electric or high-end cars)

Activates filtration when pollution levels rise outside

Used in environmental or health studies to collect air quality data over time

Helps model pollution trends and evaluate interventions

Sensor always shows very low or very high PM values, regardless of actual air conditions.

Example: It always reads "0 µg/m³" or stays stuck at "999 µg/m³".

Sudden spikes or drops without any real cause.

Inconsistent data, even in a stable environment.

No data output at all.

Sensor not recognized by the microcontroller or software.

Serial output shows errors or garbage values.

Doesn't react to smoke, incense, dust, or outdoor air changes.

You expose it to visible pollution (like cigarette smoke), but the readings barely change.

Buzzing sounds, burning smell, or heating from the sensor (rare but possible hardware failure).

Some sensors have a limited lifespan (e.g., ~8,000 hours for cheaper models).

If it's old or used continuously for months or years, degradation is expected.

Moisture or excessive dust can block the laser or photodiode.

Sensor may need cleaning or replacement.
