This pilot system offers an Arduino-based solution for real-time monitoring and automation of lathe machines, integrating temperature, vibration, and operational data to improve efficiency and safety.
Designed to monitor temperature and vibration in real time, the system enables automated alerts and preventive actions to minimise downtime and extend machine life. It also enhances operator convenience by displaying and transmitting data on an LCD via serial communication.
Vibrations are detected through analogue and digital signals, while temperature is measured using an LM35 sensor. Anomalies trigger alerts through a buzzer. Real-time data is shown on a 16×2 LCD display.
The system can be modified for expanded automation to include a relay module that activates external mechanisms. This approach supports predictive maintenance, ensures safe operating conditions, prevents damage, and enhances overall productivity. The prototype is shown in Fig. 1. Refer to the Bill of Materials table to build this system.
EFY Note:
Although the prototype shown uses an Arduino Uno, the circuit also works with an Arduino Nano, as shown in Fig. 3.
