This project puts you in control: build a multi-threat monitoring system that sniffs out LPG, carbon monoxide, and water leaks instantly, then triggers independent relays to shut off the gas valve and water supply before danger escalates. With onboard GSM, you get an SMS alert the moment something goes wrong — even if you're away from the kitchen.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA wall-mounted safety unit that continuously monitors your kitchen environment. The MQ-2 sensor detects combustible gas or smoke and activates Relay 1 to cut the gas valve. The MQ-7 picks up dangerous CO levels, sounding an active buzzer and flashing a red LED. A water sensor probe guards against floods, and when moisture shorts it, Relay 2 shuts off the water supply. The SIM800L GSM module fires real-time SMS alerts to your phone, identifying the leak type so you always know the threat. All three sensors run truly in parallel on the Arduino Mega’s multiple ADC channels — no compromises.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrate multiple analog and digital sensors on a single Arduino Mega while avoiding crosstalk and read conflicts\u003c\/li\u003e\n  \u003cli\u003eProgram logic-level relay control to safely switch 230V solenoid valves for gas and water lines\u003c\/li\u003e\n  \u003cli\u003eMaster GSM AT commands to send real-time SMS alerts with\n\n\u003cdiv class=\"kit-description\"\u003e\n  \u003cp\u003eKitchen Safety — Water probe + MQ-2 + MQ-7 monitored simultaneously.
