Ultrasonic range finder circuit
The circuit is designed to be low cost. It uses a PIC12C508 to perform the control functions and standard 40 kHz piezo transducers. The drive to the transmitting transducer can be simply driven directly from the PIC. The 5V drive...
Ultrasonic ranging
The Ping Ultrasonic Distance Sensor by Parallax features three pins: +5V, I/O, and Ground. To activate the sensor, a 5-microsecond 5V signal must be sent to the I/O pin. Following this, the sensor waits 750 microseconds before emitting an ultrasonic...
TV_CONTROL_RECEIVER
Utilizes a barium titanate transducer as a microphone, tuned with a 20 mH coil to generate peaks at control frequencies of 38.5 kHz and 41.5 kHz. A balanced discriminator detects the two ultrasonic tones. A frequency shift in the continuous...
Homebrew Utrasonic Imager
This is the electronic schematic of a homebuilt SONAR system. It utilizes a single piezoelectric transducer for both transmission and reception, which is switched from transmit (TX) to receive (RX) mode using four 4016 analog switches. A high-gain amplifier stage...
Circuit explanation for Ultrasonic Range Meter
The ultrasonic signal received by the reception sensor is amplified by a factor of 1000 (60 dB) using a two-stage operational amplifier. The first stage provides a gain of 100 (40 dB), while the second stage offers a gain of...
Ultrasonic Dog Whistles
Many commercial pest repellers operate in the frequency range of 30 to 50 kHz. The goal was to design a more powerful audio frequency and ultrasonic sound generator suitable for training dogs. This device could potentially deter dogs from barking...
ultrasonic dog whistle
It is well known that many animals are particularly sensitive to high-frequency sounds that humans cannot hear. Many commercial pest repellers based on this principle are available, most of them operating in the range of 30 to 50 kHz. The...
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...
Ultrasonic remote control switch circuit diagram
Many brands in Asia utilize ultrasonic remote control switch circuits, with some employing relays and others utilizing thyristors. The remote control transmitter is of a puffer type, featuring an ultrasound flute with both olive and flat circular shapes. This document...
