STM32 MCU WIFI IoT Kitchen Gas Safety System Ultrasonic Personnel Detection MQ4 Gas Alarm

Practice making DIY- GC 0 140 - WIFI IoT kitchen gas safety system

Design based on STM32 microcontroller --- WIFI IoT kitchen gas safety system

2. Function introduction:

Hardware composition: STM32F103C series minimum system + relay analog valve + MQ-4 gas sensor + HSR04 ultrasonic ranging + LCD1602 display + ESP8266-WIFI module + buzzer + multiple buttons

1. An Android phone APP connects to the WIFI module of the value circuit board through WIFI to realize data interaction.

2. There are manual and automatic modes. In the manual mode, the solenoid valve can be switched on and off through the APP. In the automatic mode, if any value of the gas exceeds the set value, the alarm will be turned off and the relay will be turned off. If it is not exceeded, the relay is turned on.

3. Special function, in the automatic mode, the solenoid valve can also be closed through the APP, but the solenoid valve cannot be opened.

4. Special function, in manual mode, if any value of smoke or gas exceeds the set value, the alarm will be turned off and the relay will be alarmed. But it will not automatically open the relay after normal.
