This is an M3 FTD-03NO 30MM Laser Micro Diffuse Reflectance Photoelectric Switch Laser Visible Light. The photoelectric switch uses the object to block or reflect the beam and detects the presence or absence of the object through the synchronous loop gate circuit. All objects can reflect light and can be detected. A new generation of optical switching equipment with delay, expansion, external synchronization, anti-interference, high reliability, dedicated to self-diagnosis of regional stability and intelligent features.

Features:

1. Automatically locked in the daytime to save energy.
2. Strong anti-jamming capability.
3. Simple installation, convenient and safe.
4. Standby power is small, long service life, and can effectively prolong the service life of the load.

Want a robot to hunt down heat objects or navigated with fire? This is a small form factor IR camera capable of tracking up to four heat/IR sources. The applications are plenty and can go from tracking of robots with IR transmitters for navigation to light barriers, determining the direction where the object is going, and working as a flame sensor or tracking heat sources. It’s fully compatible with Arduino with only four wires: two for power supply and two for I2C.

Specifications:

1. Operating voltage: 3.3-5v
2. Interface: I2C​
3. Detecting distance: 0~3m
4. Horizontal detecting angle: 33 degrees
5. Vertical detecting angel: 23 degrees
6. Dimensions: 32mm x 16mm(1.26×0.63″)
7. Resolution is 128×96 pixel, with hardware image processing, which can track four objects (IR emitting or reflecting objects)

Packages Includs: 

1 x DFRobot Gravity: IR Positioning Camera For Arduino

OP.90 and OP.180 are two limit switches with different orientation placements. Built based on the ITR9606, which consists of an infrared emitting diode and a silicon phototransistor.
They are used for controlling machinery as part of a control system, as a safety interlock, or to count objects passing a point. A limit switch is an electromechanical device that consists of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection
