Rangkaian Remote Control Ultrasonic

This is a remote control circuit employing ultrasonic signals. The ultrasonic transmitter circuit is build around IC1(NE 555). IC1 is an astable multi vibrator operating at 40KHz.The output of IC1 is amplifier the complementary pair of transistors ( Q1 & Q2) and transmitted by the ultrasonic transmitter K1. The switch S1 is used activate the transmitter.

Note:

• switch S1 can be a push button switch.
• The preset R16 can be used to adjust the sensitivity of the receiver.
• The frequency of the ultrasonic signal can be varied by adjusting the preset R17.Adjust it for optimum performance.

The ultrasonic receiver uses an sensor transducer (K2) to sense the ultrasonic signals. When an ultrasonic signal is falling on the sensor, it produces a proportional voltage signal at its output. This weak signal is amplified by the two stage amplifier circuit comprising of transistors Q3 and Q4.The output of the amplifier is rectified by the diodes D3 & D4.The rectified signal is given to the inverting input of the opamp which is wired as a comparator. When ever there is an ultrasonic signal falling on the receiver, the output of the comparator activates the transistors Q5 & Q6 to drive the relay. In this way the load connected via the relay can be switched. The diode D5 is used as a free wheeling diode.

Rangkaian Remote Control IC 555

Remote Control menggunakan IC 555

Ic 555 is an integrated circuit (chip) implementing a variety of timer and multivibrator applications. The IC was designed by Hans R. Camenzind in 1970 and brought to market in 1971 by Signetics (later acquired by Philips). The original name was the SE555 (metal can)/NE555 (plastic DIP) and the part was described as "The IC Time Machine". It has been claimed that the 555 gets its name from the three 5-kohm resistors used in typical early implementations, but Hanz Camenzind has stated that the number was arbitrary The part is still in wide use, thanks to its ease of use, low price and good stability. As of 2003 it is estimated that 1 billion units are manufactured every year.

Depending on the manufacturer, the standard 555 package includes over 20 transistors, 2 diodes and 15 resistors on a silicon chip installed in an 8-pin mini dual-in-line package (DIP-8).

The 556 is a 14-pin DIP that combines two 555s on a single chip. The 558 is a 16-pin DIP that combines four slightly modified 555s on a single chip (DIS & THR are connected internally, TR is falling edge sensitive instead of level sensitive).

Also available are ultra-low power versions of the 555 such as the 7555 and TLC555. The 7555 requires slightly different wiring using fewer external components and less power.

Skema Rangkaian Remote Control IC 555

The connection of ic 555 as follows:

• GND(1)Ground, low level (0V)
• TRIG(2)A short pulse high-to-low on the trigger starts the timer
• OUT(3)During a timing interval, the output stays at +VCC
• RESET(4)A timing interval can be interrupted by applying a reset pulse to low (0V)
• CTRL (5)Control voltage allows access to the internal voltage divider (2/3 VCC)
• THR (6)The threshold at which the interval ends (it ends if U.thr → 2/3 VCC)
• DIS (7)Connected to a capacitor whose discharge time will influence the timing interval
• V+, VCC(8) The positive supply voltage which must be between 3 and 15 V

Remote Control infra Merah Sederhana

By using the NE 555 and LM 567, we can make the system infra red remote control. Remote control works based on this reading frequency signal that is sent, so that the transmitter frequency signal must be the same as the receive frequency. Frequency on the remote control transmitter is determined by the value R1 and C1 based on the following equation:

As mentioned above, the remote control must have the same frequency with the frequency transmitted by the transmitter chain. Recipient of this frequency range can be determined with the following equation:

To simplify the process of tunning, R1 at the recipient install a remote control in the variable resistor (VR). while the transmitter constant value (resisitor tetep / normal). If a circuit of remote control has been completed on the raft, to know whether a circuit of working well, the first step must be done is make tunning, with the transmitter is turned on continuously, while R1 is set so that the recipient can detect the signal transmitter. If the tuning is successful, the relay recipient akan romote control switch position (nye-Tech), when it has happened means that a circuit of remote control is working well. to the next can try pressing the switch on the remote control at the sender (transmitter). should switch on when the press kutup relay at the remote recipients will move kutup (nye-Tech).
