Daoyi Sensor is a doctoral and associate professor with years of experience in sensor development Jiaxing's "Xiuhu Double Hundred Talent Plan" and "Innovative Jiaxing Elite Leading Talent Plan "Talent creation, a key project introduced by Jiaxing Science and Technology Bureau and supported by talent project funds, is a high-tech enterprise focusing on independent research, development, production, sales and services of the Internet of Things environment and water quality analysis and intelligent sensors. The team gathers experienced technical experts, and has a number of technologies in data algorithm and optical sensor manufacturing process. Daoyi Sensor is aimed at the online monitoring market of the Internet of Things. It launched multi parameter water quality sensors, UV multi spectral COD sensors, Permanganate sensors, fluorescent dissolved oxygen, turbidity, non-contact conductivity, chlorophyll a, blue-green algae, pH, ORP, ammonia nitrogen and other online water quality analyzers. The products are widely used in water environment, ecological and environmental protection monitoring, aquaculture, urban pipe network water monitoring, inspection well monitoring, smart agriculture and many other fields. Quality is the cornerstone of Dao Yi; Service is the mission of Dao Yi; Innovation is the driving force of Dao Yi. Daoyi will focus on the research and development of basic sensors, and integrate, intelligentize, miniaturize, and MEMS sensors; At the same time, we will create a water quality monitoring system platform that connects sensors to mobile phones and computers through the internet, achieving real-time dynamic monitoring of water quality.
