3.7V DIY Solar Night Light Module | Infrared Motion Sensor

3.7V DIY Solar-Powered Night Light Module with Infrared Motion Sensor

Take your DIY electronics projects to the next level with this compact 3.7V Solar-Powered Night Light Circuit Board featuring built-in infrared (PIR) motion detection. Designed for makers, hobbyists, and engineers, this SMD module automatically activates the light when it detects human body movement — making it perfect for energy-efficient, hands-free lighting applications. Runs entirely on solar power, so no external power supply is needed once integrated into your build.

Key Features

• Solar-Powered Operation: Runs on 3.7V solar input — harness free, renewable energy for your DIY lighting projects.
• Infrared (PIR) Motion Detection: Automatically switches the light ON when human body movement is detected and OFF when the area is clear.
• Automatic Night Activation: Built-in light sensing logic activates the module only at night for maximum energy efficiency.
• SMD Package: Compact surface-mount design fits seamlessly into custom PCB layouts and enclosures.
• Customizable DIY Platform: Flexible module ideal for garden lights, pathway illumination, garage sensors, security lighting builds, and more.
• Multi-Pack Options: Available in 1PCS, 5PCS, or 10PCS quantities — stock up for multiple projects or bulk builds.
• Condition: Brand new.
• Supply Voltage: 3.7V

Frequently Asked Questions

Q: What does this 3.7V DIY Solar Night Light Module do?

A: This compact SMD circuit board module integrates a solar power input (3.7V), an infrared PIR motion sensor, and automatic night-detection logic. When installed in a DIY lighting project, it automatically turns on the connected LED light when it detects nearby human body movement after dark, then turns it off again when no motion is detected — saving energy without any manual switching.

Q: What can I build with this solar motion sensor module?

A: The possibilities are wide open for makers and DIY enthusiasts. Common builds include solar-powered garden path lights, automatic porch security lights, garage entry lights, shed illumination, and STEM/electronics learning projects. Its compact SMD design makes it easy to embed in custom PCB boards or enclosures.

Q: How many pieces do I need to order?

A: This module is available in 1PCS, 5PCS, and 10PCS options so you can choose the quantity that suits your project. If you're building multiple lights or stocking up for future builds, the 5- or 10-piece packs offer the best value per unit.

Q: Is any soldering or technical knowledge required?

A: Yes — this is a DIY circuit board module intended for electronics hobbyists, makers, and engineers who are comfortable working with SMD components and basic circuitry. It is not a plug-and-play finished product; it is a component designed to be integrated into your own custom solar light project.
