<![CDATA[Sensor and microcontroller materials in the Advanced Electronics course are essential for developing automation-based technologies such as the Internet of Things (IoT) and robotics. However, learning in this course is often constrained by limited practical media, as instruction tends to be dominated by theory without adequate hands-on support, making it difficult for students to connect concepts with real-world applications. This study aims to analyze the feasibility and students' perceptions of a gas detection robot kit based on Project-Based Learning (PjBL) for sensor and microcontroller materials. The research employed the Research and Development (R&D) method using the 4D model. The robot kit was developed using an Arduino Uno integrated with gas, ultrasonic, infrared, and Bluetooth sensors. Accompanying this, a learning module was structured following the PjBL syntax. Expert validation results indicated that the robot kit obtained feasibility scores of 100% and 96% from two validators, categorized as "Very Feasible." Meanwhile, the module's feasibility increased from 86% and 89% in stage I to 91% and 98% in stage II. Furthermore, a perception questionnaire distributed to 22 students yielded a positive response with a percentage of 83%, categorized as "Very Good." In conclusion, the gas detection robot kit and the PjBL-based module are highly feasible and well-received as learning media.]]>
