Two pairs of the IR sensor modules are used to detect a person’s entry or exit from the washroom. 3) are commonly used in obstacle-detection projects. The IR sensors (FC-51) used here (refer Fig. 2: Circuit diagram of automated washroom light Infrared sensor ![]() It is built around Arduino Uno (Borad1), BC547 transistor (T1), infrared (IR) sensor modules (Module1 and Module2), and relay (RL1). 1: Author’s prototype for Automated Washroom Light Using IR Sensors Circuit and workingĬircuit diagram of the automated washroom light is shown in Fig. This will save electricity charges due to the light remaining on by mistake after use of the washroom. When the person leaves the bathroom, the light will turn off. Whenever a person enters the washroom, the light bulb (or tubelight) will automatically turn on. This project-based on Arduino Uno and IR sensors is used to automatically switch on and switch off a washroom’s light that works on AC mains. ![]()
