# mmWaveAlarm
Detect human presence behind doors and walls with Telegram Notification - DFRobot SEN0395 and ESP32C
# Brief
Sometimes you need to know what is going on outside your door. Of course you can install a PIR sensor or HCSR04 distance sensor with cables and all but, wouldn't be cool to use an indoor Milimiter Wave Radar sensor instead? This mm wave alarm is able to detect persons behind walls or doors and notify by Telegram.
