Operating on a stable 4-6V DC power supply, it offers both analogue and digital outputs with adjustable sensitivity via a built-in potentiometer. Designed for Arduino and DIY robotics, this compact module (32x17x8mm) enables precise sound-triggered control in smart devices. Sold in packs of five, it’s perfect for developers and makers aiming to build responsive, sound-activated projects. ## Description KY-037 sound detection module has two outputs, AO analogue output which gives real-time output voltage signal of the microphone and DO output when the sound intensity reaches a certain threshold, the output high and low signal. The threshold sensitivity can be adjusted via potentiometer on the sensor. Features: 100% Brand New. Size:32mm*17mm*8mm(length*width*height) Main chip: LM393, Electret condenser microphone. Working voltage: DC 4-6 V. Signal output indication Single channel signal output The output effective signal is low level When there is sound, outputs low level and the signal light Can be used for Acoustic control light , give sound and light alarm working with Photosensitive sensor ,and sound control, sound detect Circuit board output switch quantity Note: The maximum induction distance is 0.5. Package includes: 5 x microphone sensor detection modules. Review: Work fantastically - Exactly what I wanted Review: Not as good has I thought it would be. - I found the product OK, but it seems to pick up vibrations of a voice and not the voice alone. It's a pity as it's such a good price. ## Features - With LM393 and pot - High Sensitivity - Use the DC 5V power supply. - There is analogue output ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JZBL8L5 | | Antenna Location | DIY Robotics, Electronics Projects, Sound-Controlled Devices | | Best Sellers Rank | 183,295 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 247 in Microphone Elements | | Box Contents | 5 x microphone sensor detection module | | Brand | ANGEEK | | Brand Name | ANGEEK | | Colour | multicoloured | | Compatible Devices | Arduino | | Connectivity Technology | USB | | Connectivity technology | USB | | Connector Type | USB Type-A | | Connector type | USB Type-A | | Country of Origin | China | | Customer Reviews | 4.0 out of 5 stars 96 Reviews | | Enclosure Material | Plastic | | Frequency Range | 100 hz 10 khz | | Hardware Platform | Arduino | | Impedance | 1000 Ohms | | Manufacturer | ANGEEK | | Manufacturer Part Number | XF005X5 | | Microphone Form Factor | Mini | | Model Name | KY-037 | | Model Number | KY-037 | | Model name | KY-037 | | Number of Channels | 1 | | Number of Items | 5 | | Number of Packs | 5 | | Polar Pattern | Omnidirectional | | Power Source | Corded Electric | | Recommended uses for product | DIY Robotics, Electronics Projects, Sound-Controlled Devices | | Special Feature | Adjustable Sensitivity | | Special feature | Adjustable Sensitivity | | UPC | 704529985816 | ## Product Details - **Brand:** ANGEEK - **Colour:** multicoloured - **Compatible devices:** Arduino - **Connectivity technology:** USB - **Connector type:** USB Type-A - **Included components:** 5 x microphone sensor detection module - **Model name:** ANGEEK - KY-037 - **Polar pattern:** Omnidirectional - **Recommended uses for product:** Sensor technology - **Special feature:** Adjustable sensitivity ## Images ![KY-037 4-Pin Voice Sound Detection Sensor Module Microphone Transmitter Smart Robot Car for Arduino DIY Kit Pack of 5 - Image 1](https://m.media-amazon.com/images/I/61ZJWP0-vFL.jpg) ![KY-037 4-Pin Voice Sound Detection Sensor Module Microphone Transmitter Smart Robot Car for Arduino DIY Kit Pack of 5 - Image 2](https://m.media-amazon.com/images/I/519rmey1xbL.jpg) ![KY-037 4-Pin Voice Sound Detection Sensor Module Microphone Transmitter Smart Robot Car for Arduino DIY Kit Pack of 5 - Image 3](https://m.media-amazon.com/images/I/51J6nkA86wL.jpg) ![KY-037 4-Pin Voice Sound Detection Sensor Module Microphone Transmitter Smart Robot Car for Arduino DIY Kit Pack of 5 - Image 4](https://m.media-amazon.com/images/I/51+36wNpdjL.jpg) ![KY-037 4-Pin Voice Sound Detection Sensor Module Microphone Transmitter Smart Robot Car for Arduino DIY Kit Pack of 5 - Image 5](https://m.media-amazon.com/images/I/51bdvj1GIRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Work fantastically *by A***R on 6 March 2023* Exactly what I wanted ### ⭐⭐⭐ Not as good has I thought it would be. *by G***7 on 14 June 2020* I found the product OK, but it seems to pick up vibrations of a voice and not the voice alone.
