Rangkaian Pengusir Tikus Elektonik

Mice are wild animals and very annoying. "Action bawdy" it could be all kinds ranging from pooping everywhere, rummaging through closets and warehouses, spread diseases (plague), and so on. Just always make a scene! One alternative to overcome this is to use an electronic mouse repellent. In addition to environmentally friendly, this tool can also be used as a hobby and learning the distribution of electronics.

To drive these rats disorders, you can create an electronic circuit as shown below. This circuit will generate a 50Khz frequency disturbing enough for a mouse but you do not have worried because you will not hear it. This series is guaranteed by the rats would run because his ears will feel pain from the vibration signal ferkuensi.

Electronic components on the need to build a mouse repellent electronic circuit is not much, quite cheap and readily available at electronics stores. Electronic circuit scheme can be viewed directly on the image above. The circuit can be built on a dot matrix or PCB layout to make it with plain munggunakan PCB. Within a few days after the installation of this device (a continuous) will be visible results. The mouse and his relatives would be taken off some where and rumahpun rid of most annoying animals.

Heart of electronic rat repellent circuit IC 555 is already very popular, cheap and versatile. For maximum results use the loudspeaker from the PIEZO tweeter speakers electric or funnel shape. Electronic rat repellent is effective for rooms up to 200 m 2 area from the right placement. This circuit is placed in the corner of the room so that his frequency noise can be spread across the room without a hitch. Turn on continuously to keep the rats do not come back, do not worry about the electricity consumption for electrical power needed is low enough, is still greater watt/220 light bulb 5 volts.

Rangkaian Pengusir Serangga

In this section of talk about a type of insect repellent, insect repellant is a circuit that will repel insects from your home or yard with effectively. This circuit uses the frequency of bullying for the insect so the insect will go.
Pengusir SeranggaSkema Rangkaian Pengusir Serangga


For this skesta insect repellent should be installed inside or outside the home can / for speaker. This series of in-circuit oscilator adl PLL circuit / phase looked loop by using a CMOS 4047 with frequency 22 khz.gunakan external power supply for better results.

IC 4047 Description

The CD4047B is capable of operating in either the monostable or astable mode. It requires an external capacitor (between pins 1 and 3) and an external resistor (between pins 2 and 3) to determine the output pulse width in the monostable mode, and the output frequency in the astable mode.



Absolute Maximum Ratings IC IC 4047

DC Supply Voltage (VDD)...........-0.5V to +18VDC
Input Voltage (VIN)...............-0.5V to VDD +0.5VDC
Storage Temperature Range (TS)....-65°C to +150°C
Power Dissipation (PD)
Dual-In-Line...................... 700 mW
Small Outline..................... 500 mW
Lead Temperature (TL)
(Soldering, 10 seconds)........... 260°C.

Rangkaian Pengusir Nyamuk

This is a circuit diagram of an ultrasonic mosquito repeller (pengusi yamuk). The circuit is based on the theory that insects like mosquito can be repelled by using sound frequencies in the ultrasonic (above 20KHz) range. The circuit is nothing but a PLL IC CMOS 4047 wired as an oscillator working at 22KHz. A complementary symmetry amplifier consisting of four transistor is used to amplify the sound. Speaker Piezo buzzer converts the output of amplifier to ultrasonic sound that can be heard by the insects.

The circuit can be powered from 12V DC. The buzzer can be any general purpose piezo buzzer.

Description IC CD4047B

IC CD4047B is capable of operating in either the monostable or astable mode. It requires an external capacitor (between pins 1 and 3) and an external resistor (between pins 2 and 3) to determine the output pulse width in the monostable mode, and the output frequency in the astable mode. Astable operation is enabled by a high level on the astable input or low level on the astable input. The output frequency (at 50% duty cycle) at Q and Q outputs is determined by the timing components. A frequency twice that of Q is available at the Oscillator Output; a 50% duty cycle is not guaranteed. Monostable operation is obtained when the device is triggered by low-to-high transition at a trigger input or high-tolow transition at b trigger input. The device can be retriggered by applying a simultaneous low-to-high transition to
both the a trigger and retrigger inputs. A high level on Reset input resets the outputs Q to low, Q to high.

Circuit of Mouse Repellent

A simple series of mouse repellent is a oscilator the issue on the ultrasonic wave frequency range 20 - 40 kHz. The ultrasonic waves will not be heard in the ear, but we will be with the one for the mouse ear. Base Frequency will be modulation with a 50 Hz signal is obtained from the frequency PLN through capacitor C4 (to avoid a mouse immune to it) so that the resulting swing frequency between 20 - 40 kHz periodically. Effects experienced mouse feels very good, seems like we are at a music concert with the rhythm of perplexedly ragged and could not enjoy at all. (What the human ear will not hear at all).

Heart of a series of repellent electronic mouse is a type of IC 555 that have been very popular, cheap and versatile. Use of the piezo electric loudspeaker (tweeter speaker ) so that the ultrasonic frequency is more effective. Electronic rat repellent is effective for rooms up to 200 m2 area of origin appropriate placement. Can be placed in the top corner of the room so that its frequency noise can be spread to all rooms without a hitch. Turn on continuously to ensure that the mouse does not come again.
