Key Features

✔ Light-Sensitive Detection – Measures visible light intensity (low-light to bright environments). ✔ Dual Output Modes – Digital (TTL) + Analog for flexible integration. ✔ Adjustable Sensitivity – Onboard potentiometer to set light-detection threshold. ✔ LED Indicator – Lights up when light level crosses the set threshold (digital mode). ✔ Low Power Consumption – Operates at 3.3V–5V DC. ✔ Compact & Breadboard-Friendly – Easy to install in tight spaces.

Technical Specifications

Applications

• Automatic Lighting – Streetlights, garden lights, or indoor lighting control.

• Security Systems – Detect intruders using light changes (e.g., flashlight beams).

• Weather Stations – Measure daylight for solar efficiency tracking.

• DIY Electronics – Light-activated alarms or art installations.

• Energy-Saving Devices – Turn off screens/lights in bright environments.
