World Leading Chip Level High Precision MEMS Tire Pressure and Smart NOx Gas Sensor. TSING TECH is a group of teams that have a compound technical industrial background. Our Teams are from Tsinghua, Peking University, Chinese Academy of Sciences, Stanford University, and other international Top institutes, that worked in the Aerospace and German industry. We have more than 20 years of professional MEMS design and manufacturing process experiences, that have the world's leading mature high accurate vehicle silicon grade MEMS tire pressure sensor chips and smart NOx gas sensor. Our self-developed high precision MEMS Micro tire pressure sensor can reach a measurement accuracy of 0.01 bar which makes an order of magnitude compared with the traditional 0.1 bar tire pressure sensor. Nitrogen and oxygen gas sensor are used to detect NOx content in diesel vehicle exhaust in real-time, which is an essential sensor for diesel vehicle exhaust monitoring. The implementation of national V and national VI emission standards has set strict standards for NOx emission. Only diesel vehicles and old cars need nitrogen and oxygen sensors more than 20 billion yuan in the after-sales market. At present, 98% of the global automotive nitrogen and oxygen sensor market is occupied by Continental in Germany (Japan NGK provides sensor ceramic chips to Continental, and Continental provides packaging and calibration of electronic control units and final products). Domestic nitrogen and oxygen sensors mainly rely on imports, there are no mature products. We're the only global supplier of nitrogen and oxygen gas sensors from ceramic chip preparation to packaging.
