we have esp32 and microphones : mems inmp441 and/or SPH0645 and/or Sipeed. Communication channel is I2S and adc(with ads1115).need code to capture the sound ( prefer ) and send them via bluetooth / wifi to browser (baby monitor) or save to sd cards. log time and frequencies from several microphones at the same time. also, Sound Level Meter ().

I need someone to write embedded code in a Microchip PIC16F15243. The design includes a MEMS accelerometer and magnetometer that communicates with the uC vis I2C. The uC will need to process the signals from the accelerometer and magnetometer. The processing is relatively simple, a threshold above the baseline level. The device will operate on AA batteries so the uC and sensors will need to go in and out of sleep mode.

We have an ESP32 based project. The sensor is an MEMS microphone. We are collecting sound from MEMS and sending it to our server for analysis. We want to collect sound only of certain frequency to filter out other noise. We are looking for an embedded software engineer who already have experience in DSP on ESP32. What we already have: Code that is collecting sound from MEMS sensor (I2S) and sending it to our server. What we need: Add filters to collect sound of only specific frequency that we will mention.

...CONSTRUCTION Because of the surfaces' superhydrophobicity, only a small amount of water is required to create a very thin, continuous film using nanomaterials, resulting in surfaces that can reduce air conditioner use and associated energy consumption, as well as reduce heat island phenomena common in cities and urban areas. Sensors Arising nanotechnology-based MEMS sensors have additionally further developed capacities and sensitivities. MEMS sensors can either be surface mounted or installed in substantial construction itself and the sensors can be utilized for nonstop estimation and checking of the strain in structures. Smart concretes The incorporation of nanoparticles to concrete creates smart concrete that meets the needs of structural sensors. They can detec...

Need circuit design, PCB layout in altium, programing and functioning prototype Finally need a simple Android App to change settings and also to see the pressure graph in a smart phone. The circuit is used to detect a leak in an underwater camera housings. There are two modes of leak detection: vacuum pressure and water ingress. Vacuum is detected by a cheap MEMs barometric pressure sensor. The housing is sealed and a vacuum is drawn. If the housing maintains vacuum the housing is leak proof. Water is detected by a two-wire prong short circuit (one wire is MCU I/O at high value and the other is ground, when I/O is low, short circuit, water is detected). CIRCUIT BLOCK DIAGRAM Circuit consists of a CR2032 as power source, pressure sensor, bi-colored LED, a buzzer, and a tact...

About the task: I am working on a device which will act as a mouse for people with repetitive strain injury. At the moment I am using a BNO055 sensor with a ESP32 development board to control the mouse cursor. You can find the project code here. The goal of this request is to improve the project in a couple of ways, then create the necessary CAD design files, and BOM to be able to manufacture a working PCB prototype. This prototype will probably be manufactured by a third-party PCB turnkey manufacturer. So, as a summary: 1) replace the BNO sensor and associated code with a BMI270 or BMI160 and the required code (as you'll see from the current project code true North orientation is not required as we are keeping the quaternions provided from the sensor in the frame of re...

About me: I'm self-taught, with intermediate-ish knowledge of electronics and microcontroller programming. About you: You have experience working with mems IMUs and microcontrollers such as Arduino/Espressif. You have an understanding of how to manipulate the data from an IMU or gyroscope sensor to best fit the needs of a project, e.g. the appropriate BW, range, smoothing, etc. You know how to update register values of a sensor and have experience with calibration and sensor fusion algorithms. You have probably used various different sensors and can share advice about selecting between them. If you have experience transferring a project from discrete components into a PCB, that's icing on the cake. About the task: I am using a BNO055 sensor with a ESP32 development boa...

I need help finding a microcontroller that can record audio. I have tackled this problem with an arduino but the sample rate is super low. And I been been using a Electret Mic + MAX9814 Amp I would really like to start using some type of mems microphone instead but every time I look into recording audio and micro controllers I can only find arduino projects. Any help on finding a popular microcontroller that will record audio at a high quality rate easily would be appreciated. Side note I would like for it to either record to an sd card or to have enough on board storage to record for roughly an hour.
