Shenzhen EF ELECFREAKS Robotic Hand Kit para BBC micro:bit

The ELECFREAKS Octopus Light Sensor Module is a high-quality analog light sensor based on a photoresistor (LDR). Designed for the Octopus series, it provides accurate ambient light detection for educational and prototyping projects. Compatible with micro:bit, Arduino, Raspberry Pi, ESP32, and STM32, this sensor module features a standard 3-pin GVS interface and operates at 3.3V-5V DC.

Advantages

Easy to integrate with any microcontroller thanks to the 2.54mm pitch header and analog voltage output. The sensor's fast response time and wide light sensitivity range make it ideal for smart lighting, robotics, and environmental monitoring. Low power consumption ensures suitability for battery-powered projects.

Suitable for

• Ambient light detection and measurement
• Smart lighting systems (automatic brightness control)
• Robotics (line following, obstacle avoidance with light)
• Educational STEM projects and experiments
• IoT and home automation applications
