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.

The 8 channel 12V relay module provides 8 optically isolated inputs that accept a wide range of voltage. This is a great way to switch on or off AC or DC loads using your Arduino. The relays are single-pole double-throw (SPDT) and are rated for 10A @ 250VAC. The ground for the relay coils is separate from the ground for the input signals. This, along with the optical isolation, provides a total galvanic isolation between the input and output. The two grounds could be joined together if desired with the included jumper. The relay coils run on 12VDC, and the module has screw-terminal blocks for sturdy and reusable attachments for the external load. The signal and power inputs run through the male single-row header.
