Ultrasonic Mosquito RepellerCircuit by CD4017
This is a simple ultrasonic mosquito repeller circuit diagram. The circuit is designed based on the theory that pests like mosquitoes can be repelled by ultrasonic frequencies ranging from 20 kHz to 25 kHz. This ultrasonic mosquito repeller circuit utilizes...
ultrasonic switch sensor
This circuit operates using ultrasonic sound, which is sound at frequencies above 20 kHz, making it inaudible to humans. The circuit generates ultrasonic sound frequencies between 40 kHz and 50 kHz. Similar to other remote control systems, this circuit includes...
Scheme research and design of the ultrasonic range measurement system
In daily life and production, many situations such as vehicle rollback, robot obstacle avoidance, industrial well logging, and liquid level measurement in reservoirs require non-contact automatic distance measurement. Ultrasonic waves refer to sound waves produced by machinery in an elastic...
Ultrasonic-pest-controller
This circuit comprises two fundamental components: an oscillator tuned to 40 kHz and a voltage doubler with a pulse generator. The pulses generated are approximately 10 ms in duration and occur 2-3 times per second to minimize battery consumption while...
Ultrasonic bug-chaser
Low-intensity ultrasonic sound waves in the 30-45 kHz frequency band repel insects and small rodents. The unit is designed to generate a swept square wave from 30 to 45 kHz. The LM555 integrated circuit (IC) is configured as an ultrasonic...
Clap Activated Remote With CD4017 IC
The disadvantage of infrared or wireless remote control is that the remote transmitter is often misplaced. This circuit design offers a way to control ...
This circuit design addresses the common issue of misplaced remote transmitters in infrared or wireless remote...
Ultrasonic atomizer 2
The ultrasonic atomizer circuit consists of a power supply circuit, control circuit, water detection alarm circuit, and an ultrasonic oscillator, as illustrated in Figure 3-190. The power supply circuit includes a power switch (S), fuses (FU1, FU2), a timer (Q),...
Ultrasonic-pulsed-pest-controller
IC2 is a stable oscillator whose frequency and pulse width are determined by the values of R4, R5, R6, and C4. R4 is adjustable for precise frequency setting. The output from IC2 is at pin 3, which is capacitively coupled...
R-40-16 ultrasonic receiver circuit
The circuit consists of transistors VT1 through VT7 and other components. Due to the weak signal received from the transmitter, the circuit employs a multi-stage amplifier to enhance the output. This output generates a square wave pulse signal to control...
