How the sound sensor works ky
NettetI'm trying to use the KY-038 Sound Sensor (which came in a starter kit) to detect knocking on a door close to the sensor. But it keeps giving me nearly constant values regardless of any sounds nearby (or even tapping on the microphone itself). I've tried adjusting the sensitivity potentiometer; that seems to only change the value it reads, but ... NettetThis tutorial shows how to measure sound level in an environment using the KY-037 sensor and Arduino. The sensor offers two different outputs: A digital signal which is …

You would also probably look what that library you mention uses as a sensor or the general way people use it and also how it expects signal information from a sensor. – RSM. … Nettet2. feb. 2024 · So I've struggled some time with getting the KY-037 and KY-038 sensors working for ambent sound detection/tracking in ESPHome. These sensors seem to lack sensitivity to be used for anything short of detecting alarms or really loud sounds.
NettetThe KY-038 sound sensor module consists of capacitance sensitive microphone (50Hz-10kHz) and an amplification circuit. The module converts sound waves to electrical signals. It detects the sound with the help of a microphone and then feeds this sound to processing circuitry which consists of an operational amplifier LM393.
