Rainwater grate accumulated water monitoring sensor based on double-cloud redundant communication

The invention discloses a rainwater grate accumulated water monitoring sensor based on double-cloud redundant communication, and relates to the field of municipal management. In recent years, urban waterlogging occurs frequently in China, and the government makes multiple policies to strengthen prevention and control. Urban drainage waterlogging prevention facility construction needs to be enhanced urgently, rainfall law research needs to be deepened, and the digitization level needs to be improved. An intelligent metropolitan area environment waterlogging monitoring and early warning system is established and is crucial to guarantee city safety and life and property safety of people. A rainwater grate accumulated water monitoring sensor based on double-cloud redundant communication comprises a main control circuit board, an external device and a double-layer sealing shell. The beneficial effects are that the NB-IOT technology is used to realize double-cloud redundant communication, the cloud platform display
