Monitoring Principles and Sensor Technology for Four Gases and Two Dusts Sensors

Gas detection uses diffusion sampling method, allowing air to freely flow into the sensor chamber, avoiding the complexity and power consumption of pumping mechanisms. NiuBoL sensors select imported four-electrode electrochemical sensors, which include auxiliary electrodes to compensate for zero-point current, improving response time and anti-interference capability. Particulate matter monitoring is based on laser scattering principle, where the photosensitive area captures particle scattering signals, converts them to voltage values, and calculates concentration, ensuring consistency within ±10%.

This technology combination solves the problems of poor compatibility and frequent calibration in traditional sensors. The modular architecture allows independent replacement of core components, reducing downtime. For IoT solution providers, this means lower integration costs and higher system scalability.
