A few decades ago no one would have thought about automatic lights as a reality. But now a days it is possible with the help of some budget friendly electronic components. You just go into the room and see the magic happen, your LED bulb will glow automatically. The project we are going to discuss in this article does the same, we named it as “Motion sensing lights”. Now you might be wondering about the working of these lights, well the key component of these lights is “Passive Infrared Sensor”, abbreviated as PIR senor. Upon which Motion sensing lights work. WORKING PRINCIPLE OF MOTION DETECTING LIGHTS: Our X factor for these lights is PIR module. PIR detects the Infrared radiations of the nearby objects or person, after that these radiations convert into electrical signal according to the strength of the radiations and LED will be triggered to light up your…

Overview ESP-MESH is a networking protocol built atop the Wi-Fi protocol. ESP-MESH allows numerous devices (henceforth referred to as nodes) spread over a large physical area (both indoors and outdoors) to be interconnected under a single WLAN (Wireless Local-Area Network). ESP-MESH is self-organizing and self-healing meaning the network can be built and maintained autonomously. Traditional Wi-Fi Network Architecture A traditional infrastructure Wi-Fi network is a point-to-multipoint network where a single central node known as the access point (AP) is directly connected to all other nodes known as stations. The AP is responsible for arbitrating and forwarding transmissions between the stations. Some APs also relay transmissions to/from an external IP network via a router. Traditional infrastructure Wi-Fi networks suffer the disadvantage of limited coverage area due to the requirement that every station must be in range to directly connect with the AP. Furthermore, traditional Wi-Fi networks are susceptible to overloading as…
