Household-Gas-Alarm
The Home Gas Alarm is a system that alerts people with a flashing LED and buzzer alarm as soon as a change in carbon monoxide concentration is detected due to a gas leak or incomplete combustion. This simple device can improve the level of safety in the home.
This household gas alarm reference design incorporates the RL78/G10, a small, small-pin, low-power general-purpose microcontroller that uses a buzzer output controller to control the LED and buzzer. The output voltage of the carbon monoxide sensor is amplified by an ISL28113 operational amplifier, and the voltage value is converted by an A/D converter every second to obtain carbon monoxide concentration data. When it determines that a warning is required, a buzzer sounds. In addition, the RL78/G10's STOP mode function enables low-power consumption control. The RL78/G10 is a small-pin microcontroller ideal for miniaturization of consumer products.
