How to Build a Smart Wireless Doorbell System Using IoT Missing a visitor at the front door usually means missed package deliveries, keeping friends waiting outside, or missing unexpected guests. Standard doorbells only work if we happen to be sitting nearby and the chime is loud enough to hear. If we are stuck in a work meeting, listening to music with headphones, or away from home, it is easy to miss the ring, leaving… |

How to Build an Elderly Fall Detection System with XIAO ESP32-S3 When an ageing parent falls at home, the immediate injury is usually only half the danger. The real danger begins during the critical time they spend waiting on the floor for help. Lying immobile for extended periods can rapidly lead to severe dehydration, hypothermia, and muscle breakdown, even in homes where family members are regularly around. Expecting an injured… |

Build a Smart Cooker Whistle Counter Using ESP32 Almost every kitchen has a pressure cooker, but we've all had trouble handling them. It’s too easy to turn on the stove, get distracted by work, TV, or housework, and forget to turn it off. If we miss a whistle count, food gets burned, utensils get spoiled, and there are chances of accidents in the kitchen. But then again, being in the kitchen and manually counting… |

How to Build an AI-based Air Quality Monitoring using ESP32 Air is a necessity for us human beings, so monitoring it is important. Air quality is monitored in terms of the Air Quality Index(AQI), a single-number scale used to tell how polluted the air is and what health effects it might cause. Particulate Matter is the microscopic solid or liquid which is present in air in the form of dust or smoke. Particulate Matter is the… |

How to Build an IoT Indoor Weather Station Using CircuitDigest Cloud "Is it going to rain, or should I leave the windows open?" we would have asked ourselves numerous times. Now the weather is clear, but sometimes the rain will suddenly start pouring. The standard weather forecast application may give you accurate forecasts near the airport or other places, which are kilometres away from us, but it will not give us accurate forecasts… |
