Test and confirm it works well. there are plenty of algorithms out there in research papers etc, we dont want the freelancer to create their own algorithm. key requirements are low power usage. We can provide all items for the development platform. Please reply with your experience in iOT, G sensor/accelerometers an Bluetooth or Zigbee

Looking to develop a sports tracking/performance app that uses a phones/devices gps and accelerometer to measure various metrics. Thank you for all the messages regarding this project. I will be updating more details on this project in the coming days. If you have not heard from me please be patient.

I want to use accelerometer sensor on FPGA, in order to do that I need I2C protocol implementation in VHDL so I can continue my work on the project. I want the module to get the address of the sensor + bit for R/W , and the internal register address of the sensor, and get the data by reading, or write to the register.

Look, I'll tell you, so that you pay attention please: They made us install an application on our cell phone that works like an Accelerometer, we opened the app, put the cell phone on the table, they put on a Queen song and we did the following. I show you on video what was done: In the end, a data file is generated in this way (attached file 'DATA'). With this you have to do the following: 1. Demonstrate with data that the cell phone did not move, based on the accelerometer data. With F=m*a. 2. What is the frequency between the beats of the song. Using fourier transform.

I need a driver for the Bosch BMI270 IMU connected to the Nordic nRF52832 via SPI that does not use any other libraries except those that are standard in the nRF SDK. The language should be C so that it can easily be integrated with another project. The driver should expose the x,y and z accelerometer values as well as the x,y and z gyro values. Here is the datasheet for the BMI270: Here is the datasheet for the nRF52832: Sample project that uses I2C and external libraries on an Arduino: Another Sample project: Note that the BMI160 in the sample projects is an earlier version of the

I need a freelancer to collect some data and to write an algorithm to find the inclination of the crank of a bicycle with an IMU (possibly less than 3axis gyroscope and 3 axis accelerometer) on the crank, with an accuracy of +/-2 degrees. The bycicle will have several confunding motions in addition to the rotation of the the crank as moving up and downhill road, lateral inclination of the bicycle, linear accelerations, ... So we need to start thinking at all these aspects but initially study a simplified situation (for example just the rotation of the crank) . I have seen a bosch sensor or inversesense but still available to changes. I would probably will need the scripts in C++ but you can use mathlab and maybe start with a simulation.

...(preferably IRNSS ) receiver and transmit that data over LoRa. The GPS location will be sent only after the GPS accuracy reaches 20m or after 2 minutes (after reception of first GPS signal), whichever is earlier. The data will have four parts - Buoy's ID (customisable 3 digit numeric ID), GPS location, GPS accuracy and Battery life. B. The transmission has to be initiated only when an inbuilt accelerometer indicates that the buoys have not been moving much for the past 2 minutes. This is to avoid transmission when the buoys are still inside water. The antenna should be ejected outside the water level after this 2 minutes. The mechanism for ejection will be designed (and billed) separately. But the command alone for ejection should be designed as part of this project. C. The...

...firmware for an ESP32 device written for PlatformIO (basically arduino), but it has become very long and messy. I need help removing any redundant functions that are not being used, and creating a library with all the remaining functions. This will alllow the file to be less cluttered as it will call its functions from the library file. The ESP32 firmware controls a device with an ADXL accelerometer, an optional GPS unit, ethernet or wifi connectivity, LEDs and a buzzer. After starting up its peripheral devices it checks if ethernet is connected, if not it uses Wifi with Smartconfig protocol, then connects to AWS. This is done using AWS certificates stored in the SPIFFS memory. Once connected to AWS it collects the ADXL FIFO buffer of accelerations every second and sends the...

We seek someone to design and develop a small wearable device that triggers an audible alarm once the item it is attached to is removed. For example a baseball cap. Person will attach a small wearable device to the adjustable strap at the back of the baseball cap. When the cap falls off the person's head, the buzzer alarm will go off. An accelerometer cannot be used since there may not be a lot of velocity once cap falls. The device needs to be able to sense that the baseball cap has fallen off, and battery should have enough power for at least a 30 day period and be easily replaced. Device will be used indoors so not subject to sun or heat. User should be able to adjust buzzer volume, turn it off and on, and see a small light indicating when battery needs replacing. Devi...
