Shoo Dog !
Annoyance often arises from inconsiderate dog owners whose pets relieve themselves on private property. This issue is challenging to resolve through verbal or physical means, making an electronic solution more effective and amicable. The circuit begins with a commercially available...
Detected distance with ultrasonic receiver circuit diagram
The circuit operates at a voltage of 9V with a current consumption of only 5mA. It allows for frequency adjustment within the range of 150 to 180 kHz, featuring a bandwidth of approximately 20 kHz. This configuration ensures that only...
Hotel ultrasonic interference detection system based on ultrasonic probe DSP interference US0012
The circuit consists of the US0012 ultrasonic interference detection system, as illustrated in the accompanying figure. When the SEL40k termination is set to high, it selects a clock frequency of 40kHz. The US0012 module can perform several tasks: it provides...
Ranging-system
Combine an electrostatic transducer with an ultrasonic transceiver integrated circuit (IC) to create a ranging system capable of sensing objects at distances from 4 inches to over 30 feet. The broadband characteristics of transducer Y1 simplify the tuning process. The...
Ultrasonic Switch
Ultrasonic Switch. A circuit of a new type of remote control switch is described here. This circuit operates with inaudible sound waves.
The ultrasonic switch operates by utilizing ultrasonic frequencies, which are sound waves above the range of human hearing (typically...
Asia ultrasonic remote control fan speed control circuit diagram
Fans can be controlled remotely with a switch that allows for speed adjustments, and this remote control can also be integrated with other household switches. Its primary feature is the use of a sub-transmission ultrasonic transmitter, which operates without directional...
