Description:
The Red Noise Detector is sensitive to the environment, and is generally used to detect the intensity of the sound. If the sound level does not exceed the set threshold, OUT output signal will be HIGH. When the sound level exceeds the set threshold, OUT output signal will be LOW.
The Silent Sentinel Auditory sensitivity can be adjusted through the potentiometer on board. The digital output can directly drive a relay module, which works nicely as a voice activated switch. On top of that, this module also outputs analog voltage based on how loud the sound is.
Specifications:
- Operating voltage 3.3V-5V
- Output model: digital switch outputs (0 and 1, high or low level)
- With a mounting screw hole
- Frequency range: 100 ~ 10,000 Hz.
- VCC : 3.3V-5V external voltage (which can be directly connected with 5v and 3.3v MCU MCU).
- GND : External GND.
- OUT : small plates switch output interfaces (0 and 1).
Features:
- On-board LED indicator
- Threshold adjustable
- Digital Output is either high (sound detected) or low (no sound detected)
