ELEGOO 4 Channel Relay Module with Sensor Kit Bundle for STEM Projects
- This ELEGOO bundle pairs the 4 Channel 5V Relay Module with the 37-in-1 Sensor Module Kit to create a more useful setup for automation switching demos and controlled output projects. The 4 Channel Relay Module supports multi-channel relay switching for compatible low-voltage automation demos, while the 37-in-1 Sensor Kit adds light, sound, motion, distance, joystick and environmental sensing. Together, they help users move from sensor input or controller code into practical switching and automation tests. Use the combination for relay switching, automation outputs, smart control demos and load isolation practice, then expand into distance alarms, line tracking, motion triggers, light sensing and environment monitors as project ideas grow. It is a practical choice for students, makers, educators, robotics clubs and electronics hobbyists who want reusable parts, clearer experiments and more room to build beyond a single item. Relay projects should be wired carefully and used within the rated voltage and current limits.
