Objective: In this project a home security system has been designed using PIR(Motion) sensor, NodeMCU microcontroller and MQTT application. Why PIR? As PIR is small, inexpensive, low-power and easy to use. We have used PIR sensor for ensuring home security and detecting motion. Why NodeMCU? NodeMCU, a microcontroller which is WI-FI enabled,interactive,programmable,low cost,simple, smart. Why […]
