Heat Sink Aluminium Adhesive Radiator 25x25

COB LEDs are built as a matrix of LEDs, that is, a concentration of LEDs in a silicone coated tablet. The advantages of LED COB: - a light output of up to 120 lumens / watt (twice as much as LED SMD)
- the light intensity is greater without the need to concentrate the beam of light
- greater durability
- opening angle of up to 160ºC
- multidirectional light Mount LED diode on a good heatsink, add some fan, this is necessary because you have to "remove" the heat from the surface of the plate so that the LEDs last longer to place a little bit of thermal silicone in each of the placement centers. the diodes.
The thermal paste increases the thermal transfer between the diode and the metal plate used as a circuit.

For Raspberry Pi 2 and Pi 3, B and B +.
Each heatsink includes a thermal sticker. Kit 3x Blue, Green and Gold colored flat metal aluminum heatsinks features:

1 blue aluminum heatsink:
- Dimensions: 9x9x12mm
1 flat gold metal sink:
- Dimensions: 12x12x1mm
1 green aluminum sink:
- Dimensions: 19x19x8mm

The optical module sensor (reflective) with comparator LM393, which detects obstacles with high precision.
The ideal obstacle detection detector for the installation of smart robots.
TCRT5000 - reflective optical sensor that has a compact construction where the light emitter and receiver are placed in the same direction to detect the presence of a object using infrared reflection on the object.
The working wavelength is 950nm.
The transmitter is infrared LED and the phototransistor receiver.
By using LM393 comparator the module has a binary output (D0) that is at level 1 (object is detected).
The sensor allows the detection of an object at a distance of up to 12 mm.
