How I Built a Cheap Alarm System With Home Assistant and Some Sensors
To arm the system, all you need to do is turn on your automation under the Settings > Automations and scenes menu via the “Automations” tab. To disable it, just turn it off. To stop the alarm once ...
This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.
Abstract: Accurate sensor localization in wireless sensor networks (WSNs) is essential for context-aware applications, such as vehicle detection and environmental monitoring in smart cities. In ...
