Thrust Stand Force Gauge Kit with Arduino Uno & OLED — Measure Motor Thrust and Impulse with Precision

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Testing small solid-fuel rocket motors requires a reliable way to measure thrust curves and total impulse. This kit turns an Arduino Uno into a precision force gauge, using a 5 kg load cell and HX711 amplifier to capture live thrust data, an OLED to display real-time readings, and a microSD module with RTC to timestamp and store every data point. Whether you’re validating a model rocket engine for a CBSE Physics project or iterating on a prototype for the Smart India Hackathon, you’ll have a complete sensor-to-logger system ready in one session.

What You'll Build

You’ll assemble a self-contained thrust stand that secures a small motor, samples force readings at high speed, and shows live thrust and total impulse on the 0.96-inch OLED. All session data is saved to microSD with exact timestamps from the DS3231 real-time clock, so you can plot thrust curves later in any spreadsheet. The setup is rugged enough for bench testing and portable for demo events.

What You'll Learn

• Calibrating a strain-gauge load cell with the HX711 24-bit ADC
• Interfacing an I2C OLED to display live numerical values and simple graphs
• Logging sensor data to microSD with accurate timestamps using an RTC
• Computing impulse from real-time force integration and understanding rocket motor performance curves
