5V Automatic Dusk Sensor Module

The OKY3031-3 is a versatile relay module designed for light-activated control of electrical loads. Ideal for applications requiring automatic switching based on ambient light, this module offers seamless integration and reliable performance.

Key Features

- Photoresistor Sensor: Utilizes a photoresistor to accurately detect light intensity.

- Relay Control: Equipped with a relay for direct and reliable load control.

- Adjustable Sensitivity: Features a potentiometer for conveniently adjusting the light level threshold at which the relay activates.

- Easy Integration: Designed for seamless integration into a wide range of projects.

Applications and Benefits

- Automatic Lighting Control: Perfectly suited for automatically turning lights on at dusk and off at dawn, enhancing convenience and security.

- Security Systems: Can be effectively used in security systems to trigger alarms or other actions based on changes in light levels.

- DIY Projects: A valuable component for various DIY electronics projects that require light-sensitive control.

- Energy Saving: Contributes to energy saving by automatically controlling devices based on natural light availability.

The module activates the relay when the light level falls below the set threshold (dusk) and deactivates it when the light level rises above the threshold (dawn). The sensitivity can be easily adjusted using the on-board potentiometer.
