This is an infrared based sensor array which can be used in advanced line following and grid navigation robots. The array has 8 individual sensors placed next to each other. Each sensor has its own digital output and can sense the presence of a line and indicate it with a 5V logic output. On reading the the digital state of the eight sensors, the user can not only detect the line but also get to know how far the center of the robot is from the line. When all sensors sense the line, the robot is on an intersection. Features

• Uses 8 sensors for best resolution.
• Great useful in building fast line following and grid navigating robots.
• Input Voltage: 5V DC.
• Comes with easy to use digital outputs that can be connected directly to microcontrollers.
• The array has mounting holes of 3mm diameter for easy mounting.

Product Description: The MPU6050 devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon together with an onboard Digital Motion Processor (DMP) capable of processing complex 9-axis MotionFusion algorithms. The parts’ integrated 9-axis MotionFusion algorithms access external magnetometers or other sensors through an auxiliary master I2C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor. The devices are offered in the same 4x4x0.9 mm QFN footprint and pinout as the current MPU-3000? family of integrated 3-axis gyroscopes, providing a simple upgrade path and making it easy to fit on space constrained boards. The InvenSense Motion Apps Platform that comes with the MPU-6050 abstracts motion-based complexities, offloads sensor management from the operating system and provides a structured set of APIs for application development. For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps) and a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g.
