★★★ SEMUA PRODUK READY ★★★ ★★★ LGSN ORDER AJA YA★★★ The Sound sensor module is a simple microphone. Based on the power amplifier LM393 and the electret microphone, it can be used to detect whether there is any sound beyond the threshold. The threshold can be adjusted by the on-board potentiometer. Adjust the on-board potentiometer to adjust the sensitivity. The module output HIHG/LOW when the voice is Lower/higher than the threshold set by the potentiometer. Please note that this sensor can only output if there is sound beyond the threshold, but not the loudness and frequency. When the sound level exceeds the setpoint, an LED on the module is illuminated and the output is sent low. Application Idea Sound controlled Lamp; Sound monitoring Features On-board LED indicator Threshold adjustable Working voltage: 3.3V-5V With this sound detection sensor module, what you can do: You could detect whether or not a motor is running You could set a threshold on pump sound so that you know whether or not there is cavitation. In the presence of no sound, you might want to create an ambiance by turning on music. • Working voltage: DC 3.3-5V. • IC Chip: LM393. Main chip: Electret condenser microphone. • Sound detected LED: The signal light when there is sound. • Note: This sensor only recognizes the availability of sound cannot identify the size of the sound or the specific frequencies of sound. ★Paket yg didapat★ 1 pcs ★Sound Sensor Voice LM393 deteksi Suara switch★
