Sensors

A crucial aspect of any robotics project is the ability for the robot to report back information about its environment or to automatically react and adjust if certain conditions are met. For example, a contact, optical or sonic solution could be employed to detect nearby objects to restrict movement of the robot to protect itself or the objects around it.

Sub Categories

Accelerometers, Gyros, GPS, & Compasses Accelerometers, Gyros, GPS, & Compasses. Measure acceleration and track rotation with these accelerometers, gyroscopes, compasses/magnetometers, and combined inertial measurement units (IMUs) and orientation sensors.	LIDAR Light Detection and Ranging or LIDAR is a remote sensing method that uses light in the form of a pulsed laser to measure distance. LIDAR sensors provide navigation and localization for autonomous ground robots.
Contact Sensors Contact Sensors. Switches and Bumper Switches used to indicated when a physical limit has been reached.	Magnetic Guide Sensors Precision magnetic sensor for detecting and measuring the position of a magnetic track along the horizontal axis, for use in Automatic Guided Vehicles and other Automation applications.
Current Sensors An assortment of unidirectional and bidirectional Hall effect-based current sensors. They offer a very low-resistance current path and electrical isolation between the current source and the measuring circuit.	Optical Sensors - IR, PIR, Photo Optical IR Sensors. IR distance sensors make it easy to detect and range objects.
Force Sensors Force-sensing resistors (FSRs) are passive components that exhibits a decrease in resistance when there is an increase in the force applied to the sensor allowing you to create a sensor that is able to detect force or pressure.
