Digital Kitchen Scale Kit
Arduino Digital Kitchen Scale Kit: Precision Force & Pressure Logger for Soft Actuators
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform an ordinary digital kitchen scale into a laboratory-grade test rig that inflates soft actuators to precise pressures while logging force curves in real time. Ideal for robotics research, final-year engineering projects, and anyone exploring the mechanics of artificial muscles, this Arduino-based system provides calibrated, timestamped data you can trust for journal-quality results.
What You'll Build
You will solder and assemble a robust PCB controller that reads pressure from an MPX5010 sensor, measures force via an HX711+load cell, activates a peristaltic pump through a 5V relay, and stores every data point on a microSD card. A 0.96-inch OLED shows live readings, and the DS3231 RTC stamps each entry with the exact moment of logging. The result is a portable, repeatable instrument for plotting force-versus-pressure curves of soft actuators—perfect for grip strength studies, material characterization, and motion profiling.
What You'll Learn
- Assemble and solder a multi-module prototype PCB into a permanent, reliable logger
- Interface analog pressure sensors and high-precision load cells with Arduino
- Log time-series data with DS3231 RTC and MicroSD breakout boards
- Control a motorised peristaltic pump using relay logic and feedback from sensor thresholds

Who This Kit Is For
B.Tech ECE/EEE students developing capstone projects on soft robotics, M.Tech researchers needing a repeatable test bed for actuator characterization, and Smart India Hackathon teams working on assistive grippers. Research labs at IIT, NIT, VIT, and BITS Pilani will find the timestamped CSV output directly usable in MATLAB or Python analysis pipelines.
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 on the box to chat with your AI companion, or message us on WhatsApp — a real engineer will guide you through wiring, code tweaks, and calibration.
Does the kit include the silicone soft actuator?
The soft actuator is not included because researchers typically fabricate their own to match specific dimensions and materials. The kit provides the complete measurement and control system.
Can this kit be used for general force and pressure logging beyond soft actuators?
Absolutely. The load cell can measure any force up to its rating, and the pressure sensor can read gas or liquid pressure. With minor code adjustments, you can use it to characterise springs, gripper payloads, or pump efficiency curves.
What prior coding experience is required?
You should be comfortable with Arduino IDE basics. We supply annotated code templates that handle data logging, pump triggering, and OLED updates — you only need to adjust calibration values for your actuator.
Kitchen — Peristaltic pump and pressure sensor inflate silicone soft actuator to measured pressure. Force vs pressure logged.
