mcus for a gas leak alarm


Posted on Feb 5, 2014

When a gas leak occurs, a gas leak alarm must detect the problem immediately and issue an alarm. The gas detection sensor typically used in these types of alarms sends an amplified signal from the sensor to the controlling MCU. The MCU requires an on board A/D converter to read the level of the signal to be able to identify when a leak occurs. Inaddition,

the MCU needs a timer function to provide notification, either visual or audible, when a gas leak is detected. Renesas` 78K0S/Kx1+ and R8C/Tiny Series integrate an A/D converter for reading the sensor signal and a timer function to sound a buzzer. These on-chip functions reduce the number of external components required, allowing for a compact and lightweight design, reducing power consumption, and lowering cost. These MCUs are suitable for gas leak a compact and lightweight design, reducing power consumption, and lowering cost. These MCUs are suitable for gas leak alarm applications.
