            Window Alarm with Buzzer Reference Design
                    Renesas' quick solution for enhancing window security utilizes the RL78/G10 MCU
    

Image of Renesas' Window Alarm Reference Design Renesas' quick solutions feature a reference design for a window alarm with a buzzer that can be installed on windows, door entrances, and more. When a vibration caused by an outside force is detected, an alarm will sound to scare off intruders.

This window alarm solution with a buzzer features the RL78/G10 general-purpose MCU functions such as external interrupt, a timer module, a buzzer output controller, and a watchdog timer. In a normal situation when there is no vibration to a window, the device will enter STOP mode. When vibration is detected, it will release from STOP mode and sound an alarm. The RL78/G10 STOP mode function enables power consumption to be suppressed allowing for longer battery life. The window alarm with a buzzer can play a defensive and alarm role for ordinary house doors and windows, large glass windows, glass cabinets, and booths.

Features

Demonstration board includes the RL78/G10 MCU
After vibration is detected, the system will activate an audible and visual alarm
The sound of the alarm is around 80 dB and lasts 20 seconds
After the ON/OFF switch is activated, the system is powered on and starts initialization, the vibration detection sensor starts to operate 10 seconds later
Reset standby function: LED blinks with a 50 ms cycle and lasts 10 seconds
The LED blinks about every 3.28 seconds to indicate the MCU is operating normally
