Arduino-based Data Logging Prototype

I need an experienced Arduino/electronics expert to build a data logging prototype for laboratory applications. The device will monitor:

- pH
- ORP
- Temperature
- Froth height
- Airflow

The project is urgent and requires prompt completion. Ideal skills and experience include:

- Proficiency in Arduino programming
- Experience with a variety of sensors, particularly pH, ORP, temperature, and airflow
- Electronics prototyping skills
- Ability to deliver high-quality work under tight deadlines

Please provide examples of similar projects completed.
