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.

Tilt Camera Platform Anti-Vibration Camera Mount for Aircraft FPV features:
- Platform for Arduino Robotics Modeling, works with servo 9g SG90

Speed sensor module for Arduino motors features:
- Slot-type optocoupler sensor, slot width: 10 mm.
- The encoder module is a device that can help you in the creation of your robotics and automation project, whether you want to know the speed of a motor or the exact position of it.
- Output Out - Emits a low level when there is no block in the slot, otherwise it produces a high level. The operating mode: - When the sensor is blocked the OUT output is high
- Power supply: 3.3-5V - Current consumption 15 mA max.
- PCB dimensions: 25 x 20 mm

Sodium Persulfate B327 (PCB) Printed Circuit Board Etching 1kg features:
A compound for etching of printed circuit boards and pickling of copper. An ideal alternative to ferric chloride. It is readily soluble and does not crystallize from the solution. It etches evenly, ensures the sharpness of contours and minimizes undercutting. Usage: Dissolve the preparation in 0.5 l of water at a temperature of 50°C. Perform etching at 40°C (max. 50°C). Bath movement ensures quicker etching. The etching solution must not be stored in hermetically sealed containers due to the risk of developing overpressure and cracks.
