@CHAPAPPA

Hello, Thank you for the detailed description provided. I'm an IoT and embedded systems engineer with strong experience in PCB design using Altium Designer, KiCad, and EasyEDA. I've delivered more than 20 projects on the platform and dozens off of it. Many of my projects are based on ESP32s and Raspberry Pi. I've developed a relevant project to yours in terms of components and structure, but in the agritech field, it was a system for beehives that tracks environmental values in and outside the hive and measures the weight of the hive with the same Hx711. Data is then processed on the Raspberry Pi and transmitted to a cloud dashboard through MQTT (it was a custom one running on an AWS VPC, but I have experience with all similar services). I would like to share my PCB designs through chat or you can check the ones placed on my portfolio. Looking forward to cooperating. Best regards.

@Webslinger01

Hi, I have built a wearable device with BLE, IMU, and heart rate sensing streamed live to a mobile app, and a patient care robot on Raspberry Pi with AI-driven interaction, so multi-sensor acquisition, BLE, and patient-facing hardware are areas I know well. I can handle the full stack work, including PCB design, firmware for all your sensors with MQTT packetisation, and a clean dashboard with live plots and export. I work with ESP32 and Raspberry Pi Pico and have shipped systems with real field acceptance criteria. Would love to hear more about your research context. Please feel free to reach out. Himanshu

I have built a complete IoT smart home system with Raspberry Pi as the central hub — handling multi-sensor acquisition, local processing, and real-time cloud streaming. This project is a natural extension of that work. For your platform I'll deliver: • Hardware: Full schematic + PCB with ECG (ADS1292R), SpO₂/HR (AFE4490), temperature (MAX30205), VL53L8CX daughterboard for height, and HX711 load cell interface for weight. Clean analog layout — ground plane splits, guard rings, proper decoupling. • Firmware: C/C++ with RTOS tasks, double-buffered acquisition, baseline filtering for ECG, median filter for ToF height, moving average for weight. Secure MQTT over TLS with local ring buffer for reconnection. • Cloud & UI: MQTT → Node-RED → InfluxDB → Grafana. Live ECG, SpO₂, HR, temperature, height and weight plots. CSV/JSON export. Data on screen within 2 seconds. • Docs: Build guide, HX711 two-point calibration, VL53L8CX offset calibration, firmware flash walkthrough. All files under CERN-OHL-S + GPL v3. All acceptance criteria — ±2 cm height, ±0.2 kg weight, 8-hour continuous run — are achievable with this stack. Preferred MCU: ESP32 or Pico W?

@youssefhachicha

This is a serious embedded and IoT systems project, so I’d approach it as one integrated research platform rather than a collection of sensors. I would build it around a stable acquisition architecture using ESP32 or RP2040 class hardware, with clean separation between signal capture, filtering, packetization, and cloud transport. On the hardware side, I can deliver the main board design, sensor interfaces for VL53L8CX and HX711, and a BOM based on components that are actually available. On the firmware side, I’d focus on reliable long duration streaming, timestamp integrity, and calibration paths for height and weight accuracy. For the cloud layer, I’d use a lightweight MQTT based pipeline with a simple authenticated dashboard for live and historical plots plus CSV or JSON export. The key here is making the platform reproducible, documented, and stable for real research use, not just a prototype that works once. I can help structure this end to end with open hardware and software deliverables.
