Compressed Air Energy Storage Demo Kit with Arduino Mega + Sensor
Compressed Air Energy Storage Demo Kit with Arduino Mega – Store Air, Generate Electricity, Analyse Efficiency
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You will assemble a fully instrumented bench-top compressed air energy storage plant. Start by charging a small air tank with a compressor, then release the stored energy through a turbine that spins a DC generator — all while the Arduino Mega logs pressure, current, voltage, and shaft RPM. This hands-on rig mirrors the operating principles of utility-scale CAES plants used for renewables grid balancing.
What You'll Build
A complete energy storage test bed. The dual MPX5700 pressure sensors monitor tank pressure before and after the release valve. The INA219 captures turbine generator output, the Hall sensor measures RPM, and all data is time-stamped by the DS3231 RTC and saved to microSD. A 0.96-inch OLED gives real-time readouts. You can modify the control logic to experiment with different charge/discharge cycles and calculate round-trip efficiency.
What You'll Learn
- Interfacing industrial-grade pressure transducers (MPX5700) with an Arduino Mega and interpreting analog signals
- Precision current and voltage monitoring using the INA219 over I²C for generator output analysis
- Time-series data logging with DS3231 real-time clock and SD card module, including CSV formatting for MATLAB/Python import
- Measuring rotational speed with a Hall effect sensor and correlating it with electrical output

Who This Kit Is For
Engineers and advanced hobbyists tackling energy storage prototyping. It’s particularly relevant for B.Tech EEE/ECE final year projects, Smart India Hackathon challenges around renewable energy integration, and research scholars at IITs, NITs, VIT, BITS, and other institutions validating small-scale CAES concepts. ATL tinkering labs can use it as a capstone build for senior students exploring grid-scale storage analogies.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code included in the box to access the AI companion that knows every wiring detail and calibration step for this exact kit. You can also message us on WhatsApp for direct engineer support.
Do I need a compressor and air tank separately?
Yes, the kit includes all electronics and sensors; you’ll provide a small silent air compressor and a pressurized tank (a 1-litre capacity is sufficient). Our build guide recommends affordable options available on industrial supply portals.
Is the turbine and generator included?
The relay module controls the air release, and the Hall sensor measures shaft RPM. You source a miniature air turbine and a small DC motor acting as generator. We suggest tested models that match the kit’s pressure range.
How can I export logged data for analysis?
The microSD module saves time-stamped CSV files. You can open them directly in Excel, MATLAB, or Python to plot pressure curves, power output, and calculate round-trip efficiency. The AI companion walks you through the import scripts.
Compressor charges air tank. MPX5700 pressure sensor monitors storage. Release valve turbine drives DC generator.
