Implementation of Voice Based Hot-Cold Water Dispenser System Using Raspberry Pi 3

In today's generation, our busy lives have been totally automated, which simplifies things and attracts people to automated systems, which minimize human labour, putting less effort, time, and errors due to human carelessness. This system is completely supported voice-based, and it employs a Raspberry Pi circuit. It also has an IR sensor, a voice app, a Bluetooth module, jars for holding water, pipes, and a motor. During this project, the voice app detects the person's speech and transmits the appropriate information to the Raspberry Pi 3, which determines whether the water requested by the person should be hot or cold. The raspberry pi uses the information from the IR sensor to determine whether or not the glass is put beneath the pipe. The device employs infrared sensors to detect the presence of a water glass, after which the IR sensor sends a signal to the Raspberry Pi, causing the motor to start and water to flow via the pipes from the real jar (hot/cold). If the glass is not placed, the sensor sends a signal to the motor, which prevents water from flowing through the pipe until the glass is placed. This approach is frequently utilized in reception, offices, homes, and other places where people want hot or cold water by just voicing a command.
