Aiming at simple functionality and lack of flexibility of existing monitoring system

a multi-parameter factory state monitoring system based on wireless sensor networks（WSNs） is designed using STM32F103 microprocessor as core of computation and processing.The system is able to collect parameters including temperature

humidity

atmospheric pressure

and equipment vibration

movement

tilt

and datas are transmitted by wireless network to the monitoring center

so real-time remote monitoring is realized.Low power consumption design is emphasized consideration.Test results show that data packets transmission rate of the system is over 90%

temperature measurement error is less than 0.7 ℃

power consumption is low and it can accurately and stablely monitor environmental information for a long time.
