RL78/I1x Series

Solutions

Glass Break Detector Solution

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.

Smoke Detector Solution

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.

Carbon Monoxide Detector Solutions

This sensing solution uses a carbon monoxide canister. It enables detection of carbon monoxide at concentrations of 100ppm ±10ppm.

Motion Sensor Solutions

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.

Gas Leak Alarm

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.

Residential Smoke Detector

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.

Commercial Smoke Detector

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 external parts count and the overall product size.
