SEN0008 is a small, integrated and flexible TCRT5000 infrared reflective sensor module which is designed for used with DF Robot microcontroller boards, allowing it to sense the presence of an object or surface. This infrared reflective sensor uses the TCRT5000 infrared reflective sensor, which is a long-distance infrared sensitive type that excels at black and white surface detecting. This makes it ideal for a variety of applications, such as color recognition, obstacle avoidance, counting pulses, as well as color tracking and line tracing. As an integrated module, it has all the necessary components, such as a voltage regulator and an amplifier, to provide a convenient platform for easy connection and integration. The module also has an adjustable sensitivity pot, so that the sensitivity of the sensor can be adapted to the environment. In addition, the SEN0008 module also has a two-color LED indicator, which provides visual feedback for the user.
