Abstract

This study simulates a temperature and humidity monitoring system using the DHT22 sensor virtually on the Wokwi platform. The research background highlights the importance of monitoring temperature and humidity to maintain environmental conditions automatically, offering greater efficiency than manual monitoring. The study aims to test the functionality of devices and program codes without requiring physical hardware. The methods include literature review, software design, circuit schematic arrangement, and simulations with temperature and humidity parameters. Simulation results indicate the system can accurately measure temperature and humidity, display data on the LCD, and activate the relay and LED if the temperature exceeds 25°C. This research provides a foundation for developing automatic monitoring systems beneficial in daily life.

Abstract

Three-phase induction motors are electric motors that are widely used in the industry due to their reliability and efficiency. However, these motors are prone to disturbances such as unstable voltages, overloads, and short circuits, which can cause serious damage. To protect the motor, a reliable safety system is required. This article discusses the role of magnetic contactors in the safety system of three-phase induction motors, including their working principles, types of contactors, and their application to protect motors from electrical interference. The contactor functions as an electromagnetic switch that can connect and disconnect electricity automatically, improving operator safety by enabling remote operation. In addition, this safety system is equipped with sensors that monitor electrical parameters, allowing for a quick response to disturbances. Thus, the use of contactors in the safety system of three-phase induction motors is essential to maintain reliability and safety.
