Freelance Job: Arduino Vibration Monitoring System for Remote Head Diagnostics

Hong Kong

Published on www.peopleperhour.com 03 Mar 2025

I need an Arduino developer to help me build a wireless vibration monitoring system using HC-12, ADXL345 accelerometers, and an OLED display. The system will be used in the film industry to diagnose whether instability in a camera shot is caused by a remote head misbehaving or issues with the mounting structure (crane, dolly, vehicle, etc.). Project Scope: 1. Two Vibration Sensors (Transmitters) Arduino Nano (or suitable alternative) HC-12 Wireless Module (for at least 50m range) ADXL345 Accelerometer (or another suitable vibration sensor) Battery-powered for portability 2. Handheld Display Unit (Receiver) Arduino Nano or Uno HC-12 Module (to receive data from sensors) OLED Display (to show vibration severity) Data logging to SD card for analysis 3. Software Requirements: Process real-time data from both sensors Compare vibrations on the remote head vs. the structure Identify high-frequency vibrations (bad shake) vs. low-frequency movement (intended motion) Display severity levels on the OLED screen (e.g., Stable, Minor Shake, Severe Vibration) Ideal Candidate: Experience with Arduino programming (C++) Familiarity with HC-12 wireless communication Knowledge of sensor filtering (e.g., moving average, FFT, RMS analysis) Experience with real-time data processing and display If you can help design, program, and guide me through assembling this system, please get in touch with a quote and examples of relevant projects.
