Vibration Impulse Counter
This is an adaptation of the previously posted bicycle anti-theft alarm. A commenter expressed interest in modifying it for use with a threshold step plate vibration detector.
The adaptation of a bicycle anti-theft alarm into a threshold step plate vibration detector...
Vibration Alarm Circuit
This alarm is designed for use in a room or area that should typically remain motionless. In an environment devoid of movement, no vibrations will be detected, and the alarm will remain inactive. However, once the circuit identifies a vibration,...
Vibration Detector Circuit
The sensors consist of a thin strip of piezoelectric material with a rivet at one end acting as a weight. When vibration occurs, the weight moves, stressing the piezo material, which generates a spike in voltage that can reach up...
Deer Repellent/ Seismic Sensors
By attaching a standoff to the center of a 2-inch, 8-ohm speaker, it can be transformed into a vibration sensor with a natural resonance below 100Hz, which is quite effective. The implementation involves hanging the speaker from the lid of...
Vibration sensing Voice FM radio transmitter circuit ND-2 TM-801A
The circuit includes a comprehensive array of components such as vibration sensors, a follower, a lamp relay control circuit, a voice sounding circuit, a high-frequency oscillation circuit, and an AC rectifier buck power supply circuit. The vibration sensor is mounted...
Object motion detector circuit diagram
The core component of the motion detection circuit is the motion detection chip IC1 (KC778B). The signal frequency from the PIR sensor is low, ranging from 0.1Hz to 10Hz, while the bandwidth is quite broad, which the chip will optimize....
Motion Detector Sensor Circuit
This circuit is a motion detection sensor that utilizes a light source and detector as an infrared motion detector. It incorporates components such as a light-emitting diode (LED), a phototransistor, a transmitter, a receiver, an NE555 timer configured as an...
how to make vibration detectormeter
Whether it is truck throttling over the highway, an airplane soaring in the sky, a knock on the door, the purring of a cat, or simply your heartbeat, the vibration level detector circuit described here will sense them all and...
