The circuit diagram of using TV remote controller to cut off household appliance power supply

Published:2011/8/11 6:24:00 Author:nelly | Keyword: TV remote controller, household appliance, power supply

Using TV remote controller to cut off the household appliance power supply. When the infrared light-receiving diode PH302 receives the remote controller's signal, a low frequency signal is outputed by CX20106A frequency selective amplifier, this low level signal charges to C by D and R, C's negative terminal voltage drops. When it drops to lower than 1/3 VCC, the 555 circuit discharge tube is turned off, the relay is electric shocked and released, the power supply is cut off. In the circuit, RC can set action sensitivity by pressing remote controller for 3~5s. When the power supply turns on, pressing S1 circuit, then the relay is self-locking.   (View)

The receiving circuit: the infrared signal is inputed to MC3373 from 7 foot by phototube, the amplified signal outputs from 1 foot, it is transported into the 12 foot of decoder 8802. When the transmitter F is pressed, the voltage of 8802's 11 foot up to 2.5V, V1 turns on, K1 pulls in, M is forward rotation. When it receives B signal, 11 foot's voltage drops, 18 foot's voltage up to 5V, K1 releases, K2 pulls in, the motor is reversal rotation. Pressing W , 9 foot's voltage rises, V4, V5 turn on, it can drive the DC motors which under 100mA, pressing W again, 9 foot resets. When the receiver receives the transmitter's S signal, 8802 resets, 8, 9 feet are all 0V.   (View)

Published:2011/8/15 22:15:00 Author: | Keyword: contact printer

In the circuit, A1 and A2 are the timers; A3 and A4 are the second signal generators; A5 and A6 are the sound signal generator. At the input terminal of A1, the R and C time delay net is connected there, by changing the value of R, the time constants of R and C are changed, i.e the time of A1 input terminal LEV rising from low to transfer potential is changed. The oscillating frequency of A3 and A4 is 1Hz, the frequency of A5 and A6 is 1000Hz or so. In the circuit, K1 is the power supply switch; k2 is the in-out converting switch; K3 is the focus switch; K4 is the jogging switch; K6 is the 10*10 selecting switch.   (View)

Simplified bridge type thermosensitive temperature measurement circuit

Published:2011/7/27 8:21:00 Author:Fiona | Keyword: Simplified bridge type, thermosensitive temperature measurement

Circuit Work Four-leg resistors are equal, this is the most common method that the bridge circuit selects parameters,each leg of the circuit resistance takes 10K. VR1 is a variable resistor, and itsfunction is to make the output voltagebe 0 at the required temperature, when the thermistor resistance and the arm resistance are equal, adjust VR1 so that the bridge is balance. Thermistor resistance falls due to temperature rises, the differential amplifier output will rise, the output voltage depends on the thermistor constant B or increasing the voltage at the bridge.   (View)
