Detect Baby Crying

Hi brother, Well, you can, kind of detect high amplitude sounds, but The LM393 is a Comparator not an Op Amp, and what it does (the module you have in the attached picture) it compares the sound to a reference, set by the potentiometer. Here is the thing, You can definitely detect high sounds with the module, but you can never be sure that it s a baby crying or you slammed the door or a rooster's neighbor is calling nearby. For baby crying precise detection, there other techniques, that involve frequency domain comparaison. I can help you with the schematics and the arduino code, and provide support during your test. Best Regards.

I am an Electrical Engineer having specialization in Electronics Control and Power, teaching at well known University in Pakistan. I have done my BS degree in Electrical Engineering with specialization in Power. Also i hire many persons in my Company for freelancing. They know many skills like Graphic designer, Logo Designer, Video Editing and Data entry. I have taught the followings courses, and also done many projects related to these subjects as well as related to consumer electronics products. 1. Control System Design & Modelling (Continuous, Discrete, Linear, Non-Linear, Optimal, Fuzzy Logic + Matlab & Simulink) 2. Digital System/Logic Design (Verilog, VHDL, Logisim) 3. Digital Signal Processing (MATLAB) 4. Micro-controllers (8051, Arduino, PIC) 5. Power Electronics (PSIM, MATLAB, PSpice) 6. Control of Electric Machine Drives 7. Circuit Analysis and Designe etc 8. PCB Design (Proteous + Ultiboard + Altium Designer) I assure you, if you assign your project to me, you surely gonna work with me in future. Note: I also provide the services in Mechanical Engineering and Computer Science related projects.

Hi. I work as Hardware Engineer in a company that develop IOT projects. My responsibilities in the enterprise are: Design the electronic circuits (analog, digital, control and power); Develop the code for the MCU and embedded systems using software like MPLAB X IDE, Arduino IDE and Python; Test and simulate the schematic of the circuit through simulation software (Proteus and MATLAB/Simulink); Calculate the electrical parameters of the components to implement the circuits on a PCB; Design the PCB of the electronic circuits using software like Altium and Eagle; Redesign schematics and PCB layout for old prototype of circuits with the idea of update the embedded system with new technologies. I have made projects relationated with the home automation using the internet of things using Wi-Fi and Bluetooth modules (ESP8266, ESP32 and Rapsberry Pi) and TCP/IP protocol mostly, but also using UART, I2C, SPI and 1 WIRE to communicate MCU with sensor, mostly current sensors and humidity and temperature sensor (DHT22) Also, the implementation of PIC12F, PIC16F, PIC18F, PIC24F and PIC32F, to make create sub circuits to measure data from sensors, creating small devices inside if the embedded system, like the design of a digital wattmeter with I2C communication with the master (ESP12F) using the PIC16F877A, Current and Voltage transformers. All of these projects are posted on my profile. Hope that I have fulfilled your expectations and can be a good candidate to work for your project.

I'm very experienced with arduinos. Even I've made myself one. I can easily do what you want and Im not expensive. I'm just a student who tries to be study on my own.

Greetings. Dear, I have the code you need, I do something similar using claps to activate a led, but the code is adapted to what you need. I hope I can help you

I can help you because, I have experience in Arduino boards as UNO, MEGA, NANO, MICRO with different sensors and actuators.

Hello sir, I am final year student of electrical engineering i have been working with circuits and devices more than 3 years I work locally for companies Now i want to build up my future here I will give you my best and hopefully you will find me best among all others Tell me your projects detail so we can start work on it Hope to hear good from your side Thanks

Hey I am a Mechatronical Engineering student. I have had classes about Arduino and C programming. I think I can help you. It is easy task to do. Thank you for your time. @Canmakesitbetter

hy bro. i can solve your problem. your code want can i make. fast and reponsible for you bro. if you want, i will soon be make code for you. thank you.
