Unlike rotary potentiometer counter, which species rotation counts are not limited. With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0. How it works: 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. Incremental encoder: Incremental encoders give two-phase square wave. The phase difference between them 90 °, often referred to as A and B channels. One of the channels and speed-related information is given, at the same time, by sequentially comparing two channel signals, the direction of rotation of the information obtained. There is a special signal called the Z or z

The range of which is 2cm—400cm. and the range accuracy is up to 2mm; the module includes ultrasonic transmitter, receiver and control circuit. The basic operation principle is below: 2.use IO port TRIG to trigger ranging. It needs 10 us high level signal at least 3.Module can send 8 pro 40 kz square wave automatically. And will test if there is any signal returned. 4.If there is signal returned. Output one high level signal via IO port ECHO. The duration of the high level signal is the time from transmitter to receiving with the ultrasonic. Testing distance =duration of high level*sound velocity(340m/s) 2 5.electric parameter Electric parameter HC-SR04 ultrasonic module Operating voltage DC 5V Operating current 15 mA Operating frequency 40 Hz Utmost range 4 m Nearest range 2cm Measure angel 15 ° Input trigger signal 10uS TTL pluse Output echo signal Output TTL level signal. Proportional to the range specification 45*20*15 mm The sequence diagram above indicates that you just need to supply one 10 uS pulse or above to trigger the signal. Inside the module, it will send 8 pro 40kHz round electric level with testing the returning wave. Once tested that there is returning wave signal, then it will output echo signal. The pulse width of the echo signal is in direct proportion to the testing distance. Therefore, the distance can be caculated according the duration from the sending signal to receiving signal. Here is the formula below: uS/ 58=cm or uS/148=inc
