10pcs KY-040 360 Degree Rotary Encoder Module Rotation Brick Sensor Board for Arduino AVR PIC
Overview: Operating voltage: 5V Circle pulses: 20 PCB Main color: Black Size: About 31 * 19 * 29mm Instructions: By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer count, this rotation counts are not limited. With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0. incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensors. These pulses are used to control angular displacement. In Eltra angular displacement encoder conversion using a photoelectric scanning principle. Reading system of alternating light transmitting window and the window is not consisting of radial indexing plate (code wheel) rotating basis, while being an infrared light source vertical irradiation light to the code disk image onto the receiving on the surface. Receiver is covered with a diffraction grating, which has the same code disk window width. The receiver's job is to feel the rotation of the disc resulting changes, and change the light into corresponding electrical changes. Then the low-level signals up to a higher level, and generates no interference square pulse, which must be processed by electronic circuits. Reading systems typically employ a differential manner, about the same but the phase difference of the two waveforms different by 180°compared to the signal in order to improve the quality and stability of the output signal. Reading is then the difference between the two signals formed on the basis, thus eliminating the interference.

10pcs TEC1-12706 Semiconductor Thermoelectric Cooler Peltier Cooling Plate Module 12V 60W 92Wmax 40X40mm
Notice: The working condition of this item is one side cooling and one side heating. The cooling side has characters, and the heating side is blank. Must cool the heating side by using radiator or water cooling device, otherwise it will be burned. (must use thermal grease when water cooling or air cooling) Power-on more than 2 seconds without using radiator will burn this plate, at user's own risk. Only for those who know well or interested in this item. Description: Description Working Temperature Range: -50°C ~ +80°C Max Current: 6A (T h =30°C) Max Voltage: 15V (T h =30°C) Max Cooling Power: 59.1W (? T=0°C, T h =30°C) Max Heating Power: 92.4W Size: 40x40x 3.8 ± 0.1 mm Temperature Difference Range: =68°C (Q c =0, T h =30°C) Lead Length: about 300mm Size: 40mm x 40mm x 3mm Usage This cooling plate is very simple to install and use. Before installation, find a dry battery, connected to the two leads of the plate, in 1 second obviously you can feel the cool on one side and the heat on the other side. DO NOT exceed 2 seconds if you haven't use cooling device on the heating side, it will damage the plate. Ensure the electrodes of the leads and the sides of cool and heat. If you want to get bigger cool, it is recommended that double-cooling mode, which is stack two plates together, the cooling side of 1st plate absorbs the heating side of 2nd plate, the experiments prove the cooling effect of two plates is better than just one. Three will be more better, however, it will need a larger power supply support. What's in the Package: 10pcs TEC1-12706 Semiconductor Thermoelectric Cooler Peltier
