Using Arduino Uno, you'll build a security system that monitors both seismic tremors and toxic gas, blaring an alarm and cutting off a connected appliance via relay. It's a prototype that mirrors real-world safety gear for homes, labs, and industrial spaces.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble a breadboard-based dual-sensing alarm that continuously reads vibration from a SW-420 sensor and carbon monoxide levels from an MQ-7.
