"Smart environmental protection" is based on the perception of various environmental elements. Through the Internet of Things technology, a comprehensive, multi-level, and full-coverage ecological environment monitoring network system is constructed in the city. A three-dimensional grid environment management is formed through a highly intelligent

Xinhuai's wireless vibration sensor module continuously monitors the RMS speed and high-frequency acceleration on rotating equipment. It has two modes of acquisition and monitoring. It has a built-in intelligent FFT spectrum analysis algorithm that can convert the spectrum of vibration signals. It can be connected to the PC through Zigbee Real-time communication of industrial control host.

Currently, kitchens account for a large proportion of household safety incidents. In particular, the leakage of natural gas, liquefied petroleum gas and carbon monoxide has led to an increase in asphyxiation and explosions, which seriously threatens the safety of people's lives and property. Therefore, it is particularly important to install air leakage devices in the kitchen to reduce the accident rate.
