We are looking for someone to build a rf transmitter and receiver system. The transmitter will have a 3 axis accelerometer ax345 or mpu6050 connected to the transmitter which will be powered by [login to view URL] can store data every 2 sec and send it to the receiver every 1 min. This needs to be ultra lowpower and run remotely on battery for along time. The size should be very compact. The receiver will receive the data and send to web via a URL through onboard GPRS. It will be powered by DC adapter but will have Lipo battery backup. You can use stm32 chips for microcontroller and a6 module for gprs. You can suggest other options. For transmitter and receiver module please check the attached PDF. You will need to provide guaranteed working gerber files with component list and required firmware

Hello, I am Anthony from Sri lanka. I have 7 years of experience in the filed and I am very much interested in your project. I HAVE ALREADY DONE MOST PARTS OF YOUR PROJECT. I AM USING MPU6050 AND ARDUINO NANO. BUT IF YOU WANT I CAN SWITCH TO STM32. CAN I SUGGEST A DIFFERENT RF TRANSMITTER ? ITS RELIABLE AND WE ARE ALREADY DEVELOPED THE HARDWARE AND THE CODE WITH IT. IT CAN WORK UP TO 500M. THE BATTERY WE HAVE BEEN USING IN THE SAME KIND IF DEVICE IS LIPO 18650 AND IT CAN RUN THE DEVICE FOR 6 HOURS CONTINUOUSLY. SHALL WE USE SIM800 FOR GPRS ? BUT THE ONE THAT YOU HAVE SUGGESTED IS ALSO OK WITH ME. I CAN DEVELOP A PROTOTYPE AND ALSO SEND YOU A WORKING DEVICE TO TEST. Why you should hire me ? * As a full time freelancer I have my own PCB fabrication work shop and testing lab. So there is no problem doing live tests with you after the device has been developed. * My workshop is equipped with CNC machine, FDM 3D printer and DLP 3D printer. So there is no problem designing and printing plastic parts you required. Please contact me if you are interested. Thank you Anthony

We did such a project, there are ready samples for demonstration. The microcircuit CC1310 is used (as in the description provided), the GSM modem SIM800, also an accelerometer and a gyroscope are installed on the board. I can send a photo by mail, the firmware is ready. Required to adapt to your dimensions. We will be happy to help you.

Hi, Found out that you are looking for a developer to implement a solution with transmitter and receiver to send gyro data with minimum power usage and send those data to web server using the receiver. I can do that for you sir. I have worked with RF modules and as well as arduino, STM32 and Raspberry Pi 1) Developed an car security system using arduino uno, Sim808 module and gps to track and control a car 2) Have worked with MPU6050 to implement a step counter and a real time mapping system 3) Have wireless communication experience with BLE, Bluetooth Classic, TCP/ip, MQTT and RF I can complete the project within the requested time with no bugs. I will support my code life time for free Thank you

Hello, I have got involvet in many microcontroller projects (including arduino) and designed and made simple PCBs. The construction is mainly modular so it won't give as too much trouble and get woried about RF design black magic ;-). I can provide you with the code and gerebers for both the remote sensor and the base unit. But I have some important questions: 1) Is it a prototype or one off design or it should/could be mass produced? 2) Is it necessary to use the speciffic transceiver ? What about the required range? I could give you a much quicker delivery but there is some time to wait for the PCBs to get made. Feel free to contact me.
