Arduino Sensors: Infrared Sensors

01Basic Understanding(Image source: Internet)Model:HS-S01AName:Infrared Detector (Infrared Sensor)Series: SensorDescription:It is an infrared transceiver device, consisting of a pair of infrared emitting and receiving tubes.Usage Scenarios:Commonly used in infrared detection systems for smart cars, robots, and automated machinery in logistics, playing an important role in artificial intelligence-related practices and applications, aligning with the requirements for cultivating students’ practical abilities and understanding of technical principles in the “General Education Guidelines for Artificial Intelligence in Primary and Secondary Schools (2025 Edition)”.Disciplinary Integration:Physics, Information Technology, LaborEthical Education:Discuss the risk of misjudgment of sensors in autonomous driving; analyze the impact of technical limitations on AI decision-making;02Technical ParametersInfrared emission and reception mechanism:The emitter in the module continuously emits infrared rays at a specific frequency. When the infrared rays encounter an object in the detection direction, reflection occurs.Parameter Analysis:G: GND (Power Negative/Cathode)V:VCC (Power Positive/Anode)S: Digital SignalA: Analog Signal03Code Example04Safety Regulations1.Remember to disconnect power when connecting;2. Check for reverse connection before powering on to avoid damage;3. Do not look directly at the infrared emitter;4. Avoid high temperature and strong light environments;5. Do not place liquid solutions on the table;
