Ultrasonic Radar AlarmCircuit Project
The circuit consists of an ultrasonic transmitter and a receiver that operate at the same frequency. Ultrasonic piezoelectric transducers serve as the output and input devices, respectively, with their frequency of operation determined by the specific devices used. The transmitter...
Ultrasonic Remote Control Receiver Circuit
A GC Electronics P/N J4-815 transducer is utilized to receive 40-kHz acoustic remote-control signals. The receiver activates a relay to control another circuit.
The GC Electronics P/N J4-815 transducer is designed specifically for the reception of 40-kHz acoustic signals, which are...
ultrasonic mosquito repeller
The circuit diagram of an ultrasonic mosquito repeller is presented. This circuit operates on the principle that sound frequencies in the ultrasonic range, above 20 kHz, can repel insects such as mosquitoes. It utilizes a Phase-Locked Loop (PLL) integrated circuit,...
Ultrasonic Range Sensor
The Panasonic transducers are no longer available, but the design remains interesting as an example. J1 connects to the RCX. D1 to D4 create a bridge rectifier to obtain local power from the RCX, which is stored on C7 and...
digital step km counter circuit schematic
This circuit measures the distance covered during a walk. The hardware is housed in a compact box that can be conveniently placed in a pants pocket. The display is designed as follows: the leftmost display, D2 (the most significant digit),...
ultrasonic transmitter 40khz
A 40kHz ultrasonic transmitter circuit consists of three oscillators (F1, F2, and F3), with F3 generating a 40kHz square wave output. The frequency is primarily determined by components C1, R1, and an adjustable resistor (RP). The excitation output from the...
Ultrasonic Transmitter Sensor Switch circuit
This circuit explains alternate wireless switching using an ultrasonic sensor. The distance of the switching range should be more than 10 meters.
The described circuit employs an ultrasonic sensor to facilitate wireless switching, allowing for the activation or deactivation of devices...

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...
