The Elecrow Crowtail – Light Sensor 2.0 (Model: CT0013LS) is an analog light sensor module designed to detect ambient light intensity. Utilizing the GL5516 photoresistor, the sensor's resistance decreases as light intensity increases, allowing for the measurement of light levels in various environments. This module operates with a supply voltage of 5V and outputs an analog signal that can be read by microcontrollers such as Arduino. The onboard LMV358 operational amplifier ensures accurate voltage following, providing a stable and reliable output signal. The Crowtail interface simplifies the connection process, making it easy to integrate the sensor into your projects without the need for complex wiring. Its compact dimensions (20.0mm x 20.0mm x 6.8mm) make it suitable for applications where space is limited.
