The PWM signal generator module can output square wave / rail-shaped wave / triangle / sawtooth / sine wave signal the frequency range of 10Hz~300KHz adjustable duty cycle of 2%~98%. Adjustable output signal frequency wave crest arc trough arc rise time fall time and so on. Note: Adjust the capacity of C29 can be changed the output pulse frequency variable range. Up to 300KHz output. Note: 1. About the output amplitude: sine and triangle wave sawtooth minimum output amplitude is about 30% of the supply voltage peak and PWM square wave square wave output amplitude is about 80% of the supply voltage peak. For example: 12V power supply then: the output amplitude sawtooth sine triangle wave is 4V-VPP (12V x 30%) or so the output amplitude PWM square wave rectangular wave is 9.6V-VPP (12V x 80%) about. Output amplitude adjustment potentiometer adjustment range is: supply voltage 30%~80% VPP One thing to note is that if the gain adjustment potentiometer is too big or too small change it will output variant wave distortion. 2. About power supply voltage. Recommended operating voltage is 12~18V so the effect will be better. But this module is to supply 10-30V can work but must not exceed 30V otherwise it will burn IC if the voltage is below 10V then the module will no wave output. 3. About current drive capability and supply current the output current drive capability of the output signal is about 10mA power supply current can be as long as there are more than 30MA. 4.

External shocks capacitance C1 C3 C4 C2 C29 corresponding capacitance are: 100PF 1NF 10NF 0.1UF 1UF five bands of frequency adjustment range adjacent frequency of 10 times. Also if you need to get a high-frequency signal 80KHz~300KHz to do the following: A. Department must jumper cable leads from the switching signal. B. external shocks capacitor to be replaced less than 100PF the smaller the capacitance the higher the frequency. 5. About the output waveform adjustments. A. Triangle (positive and negative) to adjust the sawtooth. B. sine adjusted. Jump sine jumper position. Adjustments along time potentiometer can change the slope of the sine wave is positive clockwise or counterclockwise direction. Adjusting frequency potentiometer can change the frequency of the sine wave. Adjust the curvature of the sine wave peaks valleys radian sine wave can change potentiometer peaks and troughs radian radian shape. It should be noted that the function of the two potentiometers functions are adjusted too far in the exchange. That is the peaks will become standard tune trough the trough will become standard tune peaks but are likely to affect the performance of wave. C.PWM. Square wave rectangular wave adjustments. Jumper jump PWM. Square wave rectangular wave position. Adjustments along time potentiometer can change the PWM. Duty cycle square wave rectangular wave. Adjusting frequency potentiometer can change the PWM. Frequency square wave rectangular wave. Accelerating wave potentiometer can be fine-tuned. Under normal circumstances you can not ignore.

Jtron HB100 10.525GHz Microwave Doppler Wireless Radar / Detector Probe Sensor - Green + Silver

HB100 microwave modules is the use of Doppler radar (Doppler Radar) design principles of the microwave moving object detector mainly used in automatic door control switch security systems ATM cash dispenser automatic recording control system automatic train signals etc. places. HB100 10.525GHz standard microwave Doppler radar detector the detection method in comparison with other detection method has the following advantages: 1 non-contact probe; 2 independent of temperature humidity noise air dust light other effects suitable for harsh environments; 3 anti-RF interference ability; 4 the output power is small constitute a hazard to humans; 5 distance: detection range over 20 meters. Doppler principle Introduction: Doppler theory based on time when radio waves hit an object in the process of moving the wave is reflected the frequency of the reflected wave will move across the state with an object is changed. If the touch position of the object radio wave is fixed the frequency of the reflected wave and the transmitted wave frequency should be equal. If the object moves in the direction of transmission the reflected wave will be compressed that will increase the frequency of the reflected wave; conversely the frequency of the wave will be reflected decreases. According to the principle of the Doppler microwave detectors designed by the FET source media DRO microwave oscillation (10.525GHz) power splitter transmitting antenna receiving antenna mixers detectors and other circuit (Figure 2). Outwardly directed microwave transmit antennas when the object is encountered and the reflected wave received by the receiving antenna a mixer and then to the oscillation mixed at low-frequency signal after detection of the reaction speed of moving objects.
