Material: The sensor module is made of aluminum alloy, which is enduring and has good heat dissipation performance, ensuring the long-term stable work of the sensor. Efficient detection of PM2.5: This sensor module is used for PM2.5 detection, and the counting efficiency reaches 50% at 0.3um and up to 98% at ≥0.5um, ensuring the accuracy of the test results. Fast Response: The response time is ≤10 seconds, which can monitor air quality changes in real time and respond quickly to environmental changes. Zero Error Alarm: It has a 0 error alarm rate, effectively reducing false alarms and improving the reliability of monitoring. Continuous Acquisition: The sensor module supports continuous data acquisition, responds to air quality changes in real time, and uses the principle of laser scattering to ensure the accuracy and real-time nature of the detection data., Weight: 0.0661386786 Pounds, Manufacturer: Fafeicy
