IoT-Based Motion-Triggered Voltage Monitoring System Using PIR Sensor

This paper presents the implementation of an Internet of Things (IoT) based solution for real-time motion detection and continuous voltage measurement to achieve more energy efficiency and reliability. In the model, a Passive Infrared (PIR) sensor is used to detect motion, while a voltage sensor is used to continuously measure the supply voltage. The motion detection system uses a low-power electronic device with a wireless-enabled feature to connect and transfer the data to an loT cloud platform. This design
monitors and ensures immediate notification when motion is detected, and continuously tracks the voltage
consumption and electrical fluctuations to prevent power-related failures. By using dual function, this
motion detection system increases the reliability and automated solution over conventional detection. The
experiment was conducted with distance vs accuracy and response time with distance. The results obtained
from experimental tests achieved a detection accuracy of 98% within a range of up to 7 meters. Hence, the
proposed system demonstrates a low-cost and effective method for a smart energy monitoring application.
