DEVMO 3PCS Mic Microphone Sensor High Sensitivity Sound Detection Module Compatible with A-rduino PIC AVR

The DEVMO 3PCS Mic Microphone Sensor is a versatile sound detection module that can be used with various microcontrollers such as Arduino and Raspberry Pi. While some users found the initial setup confusing due to lack of clear documentation, others were able to successfully use the modules after some investigation. One user discovered that the potentiometer needed to be adjusted to find the triggering threshold, which then allowed the module to work as a digital sound level sensor. They noted that a passive low pass filter could easily remove the noise present in the analog output of the microphone. Overall, if the goal is to have a digital sensor for noise level, this module is a solid choice with rapid triggering capabilities. However, when connected to an ESP8266, some users experienced too much noise interference, making it difficult to pick up sound unless very close to the microphone. The module worked better when connected to an Arduino Uno, providing satisfactory performance. In terms of customer service, one user had a positive experience with the seller after receiving an order with missing modules. The seller was understanding and quickly sent the missing items, resulting in a great overall experience. Overall, the DEVMO 3PCS Mic Microphone Sensor is a decent option for digital sound level sensing with the potential for noise interference in certain setups. Users may need to spend some time adjusting the potentiometer and filtering out noise to achieve optimal results. **
