People’s daily life has become easier due to the rapid technological development and adoption in recent years. The kitchen is a common and important place in a house which is getting automated day by day. Now-a-days the kitchen is getting smarter with the blessings of IoT and AI technologies. Safety is the main concern that must always be ensured in the kitchen. Unwanted gas and water leakage, sudden fire, excessive temperature rise, and humid environment should be identified immediately, and necessary measures should be taken. Security at home is a great issue where unwanted gas and water leakage, sudden fire, excessive temperature rise can have a threatening consequence. A gas leak can suffocate people in small, confined areas and ignite a fire, which can be more dangerous. The MQ-7 sensor is used to detect unwanted gas (Carbon monoxide gas) leakage inside the kitchen that can save the kitchen from above mentioned situation. When MQ-7 detects gas in the kitchen, the buzzer instantly activates and starts to play. Additionally, the PIR sensor is used to sense the existence of humans inside kitchen and the light become on, which saves power. Arduino IDE and ESP32 board were used to build the system.
