According to the requirements of industrial field for H2 monitoring

a remote H2 monitoring system based on CAN bus is designed.A single chip embedded with CAN module is used to build CAN communication network to realize the remote monitoring of H2.The network node is divided into intelligent monitoring node and display node

and they works independently.It is showed by the real results that the system has many advantages such as low cost

high precision

strong anti-interference ability

and it can realize on-line monitoring and has good prospect of engineering application.
