I’m building a compact wearable that runs on an ESP32 and need firmware that reliably powers its core features: health monitoring and fitness tracking. The device integrates three sensors—heart-rate, accelerometer, and temperature—so the code must acquire, timestamp, and store data from each, handle basic preprocessing (e.g., simple averages or thresholds), and expose clean interfaces for a companion app to read the results. Power efficiency and stability are critical because this is a body-worn product. Please structure the project so I can adjust sampling rates, sleep cycles, and any calibration constants without rewriting large sections of code. Deliverables • Well-commented ESP-IDF or Arduino framework source code that compiles error-free • A brief README outlining build steps, pin assignments, and how to extend or modify sensor routines • A short test routine (serial or BLE output) showing live readings from all three sensors I’ll flash and run the firmware on my hardware to confirm that all three streams operate continuously for at least two hours without crashes or significant data loss.

I’m an electrical engineer with 7+ years of experience in embedded systems and ESP32-based wearable and low-power designs. I have worked on many sensor-based projects using heart-rate, accelerometer, and temperature modules with stable, efficient firmware. I can deliver clean, well-commented ESP-IDF/Arduino code that logs, timestamps, and processes data, with adjustable sampling rates, sleep settings, and calibration values. You’ll receive a README, pin details, and a test routine showing live sensor output. I’m ready to build a reliable and power-efficient firmware for your wearable.

I'm a strong fit for this project because I’ve already built several ESP32-based wearable and sensor-heavy systems where stability, low-power operation, and clean modular firmware were the main priorities. I’m comfortable with ESP-IDF as well as Arduino-based builds, and I’ve worked extensively with heart-rate sensors, IMUs/accelerometers, and temperature probes. That experience lets me design a firmware structure that’s easy to tune, power-efficient, and reliable during long continuous runs—exactly what a body-worn device needs. Project Proposal I’ll build a modular firmware stack where each sensor has its own driver, sampling task, and configurable parameters (sampling rate, averaging window, calibration constants). A central timestamped data manager will collect readings, perform lightweight preprocessing, and expose clean APIs for the companion app (BLE or serial). Power control will include adjustable sleep intervals and task-level duty cycling to minimise consumption without affecting data integrity. You’ll receive: • Well-commented, cleanly structured source code (ESP-IDF or Arduino) • A clear README covering wiring, config points, and how to extend sensor logic • A simple test mode that streams all three sensor values live to verify two-hour stability I can deliver a robust, maintainable firmware package that’s easy for you to evolve as the wearable develops.

I can deliver the complete ESP32 wearable firmware within a single day. I already have stable firmware modules for heart-rate, accelerometer, and temperature sensors, so adapting them to your hardware and project structure will be fast and reliable. I’ll structure the project so you can easily adjust sampling rates, sleep cycles, and calibration constants without touching the core logic. The firmware will focus on low power consumption, stable data acquisition, and clean modular design.

Hello, thanks for the clear description — this is a very natural fit for my background in ESP32, sensors, and low-power embedded systems. I can structure your firmware as a clean, modular project where each sensor (heart-rate, accelerometer, temperature) has its own driver and sampling task, and a central “data manager” handles timestamping, storage, and communication with your companion app. My approach Use ESP-IDF or Arduino framework (your choice), with configuration collected in one header or config file (sampling rates, thresholds, sleep timings, calibration constants).
