Based on wireless self organizing network monitoring system of 433 MHz

signal conditioning circuit

signal acquisition and processing circuit

the power management module and man-machine interface of constant potential electrolytic type chlorine gas sensor are designed

a communication platform based on star topology is built.Problem of monitoring blind spots which comes from the wireless module in lack of battery power status is solved

and the hardware and software design of real-time monitoring system for the chlorine gas content in environment is completed.The system is stable in operation

easy to expand

and has broad application prospects.
