29132: Sound Impact Sensor/Trigger, 5V, 555 Timer

Summary

The Sound Impact Sensor provides a means to add noise control to your project and responds to loud noises such as a clap of the hands. Through the on-board microphone, this sensor detects changes in decibel level, which triggers a high pulse (via 555 timer) to be sent through the signal pin of the sensor.

The Sound Impact Sensor has a maximum detection range of 3 meters. However, if you plan to use this sensor in an area where environmental factors can trigger false readings, the range can be shortened by adjusting the potentiometer on the front of the board.

Key Features:

Detection range up to 3 meters away
On-board potentiometer provides an adjustable range of detection
3-pin SIP header ready for breadboard or through-hole projects
Easy interface to any microcontroller with single bit active-high output
Built-in series resistor for compatibility with the Propeller microcontroller and other 3.3 V devices
