Research and Development of Chlorine Leak Detector Based on ARM

In this paper, the hardware and software design of the chlorine leakage inspection instrument based on STM32F103ZET6 MCU is introduced. The design of the constant voltage circuit, signal conditioning circuit (including filtering and amplifying circuit), power supply circuit, display circuit and alarm circuit, and through the GPRS module and the cloud server platform to realize data storage and remote viewing. Finally, through the host computer LABVIEW software to query the historical data stored in the cloud server. The equipment can be widely used in ten petrochemical, papermaking, textile, water treatment and other occasions.
