The MPM10-BS MemsFrontier is a compact and highly-integrated laser dust sensor designed for accurate real-time monitoring of PM2.5 and PM10 particulate matter concentrations in the air. This sensor uses laser scattering technology to detect particles and a unique air duct design where both the inlet and outlet are on the front side, which simplifies the structural design of air purification products. Its 8-pin interface provides a stable and reliable communication link for data transmission.

🧼 Calibration & Maintenance
The MPM10-BS is factory-calibrated and does not require user calibration. For long-term accuracy, it is important to keep the sensor's air inlet and outlet clean. Dust buildup inside the sensing chamber or on the fan can affect performance. Periodically, you can use compressed air (at a low pressure) to gently blow out any dust from the air channels. Avoid using water or any liquid cleaners.
⚠ Safety Information
Ensure the sensor is powered off before handling or wiring. The laser inside the module is low-power but should not be tampered with. Do not look directly into the laser component. Avoid exposing the sensor to high humidity, as moisture can condense inside the sensing chamber and damage the electronics. Do not block the air inlet or outlet during operation, as this will prevent accurate readings and may damage the internal fan.
👍👎 Pros & Cons
| Pros | Cons |
|---|---|
| High accuracy for PM2.5 and PM10 measurement | Laser sensors can be sensitive to high humidity and temperature changes |
| Front-facing ports simplify product design | More expensive than simple dust sensors like GP2Y1010AU0F |
| Active air sampling with an integrated fan | Requires a serial interface (UART) to communicate with a microcontroller |
| Reliable digital output for precise data | May require a specific library for proper data decoding |
