Dream Beam - Tr Adjustable Sensitivity
Dream Beam - Tr Adjustable Sensitivity Overview
Dream Beam - Tr Adjustable Sensitivity is an intelligent light detection sensor from Sadat Akhavi Academy – part of the LED Adventure Series. It combines active and passive electronic components to automatically detect ambient light levels and control LEDs or external modules.
What is Dream Beam - Tr Adjustable Sensitivity?
Dream Beam - Tr Adjustable Sensitivity is a smart light sensor kit that uses a light-dependent resistor (LDR) to measure environmental brightness. It employs an NPN transistor as an electronic switch to turn lights ON or OFF based on detected light conditions, making it perfect for automated lighting applications.

Care & Safety Instructions
Our educational kits are designed for learning, experimentation, and skill development purposes only. They are not intended for production, commercial, industrial, or safety-critical applications.
To protect the kit and its components, we recommend using an appropriate enclosure or protective case during operation and storage. Unless specifically stated in the product documentation, do not connect the kit directly to mains power.
Some kits may require the use of tools such as soldering irons, hot glue guns, wire cutters, drills, or other equipment during assembly. These tools can cause injury if used incorrectly.
Children and inexperienced users should only use these kits under the supervision of a parent, guardian, teacher, or other responsible adult. Adult assistance is strongly recommended whenever power tools, heat-producing tools, sharp tools, or electrical equipment are involved.
Always follow safe working practices and use appropriate personal protective equipment when required.
