Wuhan Micro & Nano Sensor Technology Co., Ltd. is a high-tech company of R&D, manufacture and sales, focusing on environmental sensing solutions. Founded in April 2015, we have applied for numerous key patents, and have been awarded "National High Tech Enterprise" as well as "Authentication on Quality Management System (ISO9001:2015). Our products can meet the requirements of ROHS, REACH. The new generation of MEMS gas sensor which developed by ourselves independently, features in small volume, low power consumption, light weight, high sensitivity, long life, low cost, ease of integration and realization of intelligence. It can be applied widely in industry, traffic, environment, security, consumer electronics, and building applications where the goal of energy conservation, emissions reduction and the early warning detection of harmful gas can be achieved successfully. Due to its small size as the green bean, the gas sensor can be embedded into all kinds of mobile Internet and IoT applications. Our partners come from various fields such as detector, purifier, smart home, intelligent kitchen appliance, smart wear, IoT and cloud data, some of whom are well-known domestic and overseas home appliance manufacturers. More importantly, the era of 5G could usher in a breathtaking point of new application.
