Gas leak detectors play a critical role in identifying potentially hazardous gas leaks and then alerting people when a dangerous gas has been detected. Renesas’ RL78/I1D, RL78/G12, RL78/G13, and RL78/G14 16-bit microcontrollers (MCUs) integrate an A/D converter for reading a 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 gas leak alarm design, reducing power consumption and lowering cost.
