NIDS (New Innovation & Development of Sensors) industrializes ultra-precise sensors based on advanced MEMS and nano materials techniques. Our main products are dust detection sensors used in air purifiers, Water Flow sensors used in water purifiers, and indoor air quality monitors. We recently supplied our self-developed optical sensors to several prominent clients.The dust detection sensor used in the air cleaner assembly has annual sales of 60 million units, 30% of which are exported. Production capacity is 100 million dust sensors, 100 million flow sensors, 20 million dust indicators units and 60 million turbidity sensors. The company acquired ISO 9001 in 2002. NIDS was established in 2000 with capital of USD1.7 million.
