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 with ultralow 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. 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
