Shenzhen Wanyi Technology Co., Ltd. is a high-performance dust detector developed and produced based on years of instrument development experience and in combination with sensor technology at home and abroad. It uses the internationally advanced optical diffuse light relative mass concentration method to measure PM2.5, PM10, temperature and humidity in the environment. It has the characteristics of fast response time and easy maintenance. At the same time, the structure adopts the aerodynamic principle to achieve automatic real-time sampling, And it is suitable for long-term online use; The memory is 60M, which can store the data in real time and export it as a USB flash disk to realize data, curve and automatic drawing; So as to facilitate analysis and research. At the same time, the PM2.5 detector can be equipped with the wireless cloud platform technology of Wanyi Technology to upload data to the cloud in real time, query and control at any time and anywhere, providing the necessary tools for creating intelligent monitoring.
