This solution uses a microphone to detect when the glass is broken. Active filtering for the microphone is implemented using the microcontroller's onchip low-power op-amp. Reduces costs while achieving extended operation on battery power.
This solution uses an infrared LED and an optical receiver to detect the presence of smoke. The low-power RL78/I1D with on-chip sensor amplifier helps reduce system cost while achieving extended operation on battery power.
This solution uses pyroelectric motion sensors to detect the movement of persons. Two sensors are used to allow detection of the direction of movement. The microcontroller's on-chip low-power op-amp reduces the system cost.
Renesas’ RL78/I1D, RL78/G12, G13, G14 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.
Renesas’ RL78/I1D, RL78/G12, G13 and G14 integrate on-chip the peripheral functions necessary for use in smoke detector design, making it possible to reduce the overall product size. The low power consumption improves battery life and this is ideal for smoke detectors that need long-term operation.
