Liquid Crystal Phase Transition Monitor Kit with Arduino Uno + Sensor
Build a Liquid Crystal Phase Transition Monitor with Arduino Uno and Precision Sensors
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a scientific-grade liquid crystal phase transition monitor that correlates temperature, light transmission, and turbidity to pinpoint phase changes in real time. This kit turns an Arduino Uno into a lab instrument, logging multi-sensor data with timestamps for materials science experiments or advanced STEM demonstrations. The dual DS18B20 probes, BH1750 light sensor, and turbidity sensor work together to capture the subtle optical shifts that define nematic-to-isotropic transitions.
What You'll Build
A functional monitor that logs temperature from dual DS18B20 probes, light intensity via BH1750, and turbidity, all displayed on a 0.96-inch OLED screen and recorded to microSD with timestamps from the DS3231 RTC. You'll see exactly when a liquid crystal sample shifts from ordered to disordered phase, with data ready for plotting and analysis.
What You'll Learn
- Calibrating multiple analog and digital sensors for coordinated data acquisition
- Implementing real-time clock timestamping for time-series phase analysis
- Creating an OLED dashboard for instantaneous phase state visualization
- Integrating a turbidity sensor to detect optical changes during phase transitions

Who This Kit Is For
This advanced kit suits B.Tech ECE/EEE students building final-year projects, research scholars in materials science or condensed matter physics, and participants in Smart India Hackathon tackling IoT instrumentation challenges. CBSE Class 11-12 students with strong electronics background can use it under mentorship, while ATL Tinkering Labs and IIT/NIT/VIT/BITS lab courses will find it a ready-to-deploy experiment.
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 to open the AI companion, which walks you through wiring, code, and calibration. If you still need help, message us on WhatsApp for direct troubleshooting.
Can I use this kit for other phase transition experiments, like in polymers or alloys?
Yes, the sensors are versatile. The DS18B20 probes handle any temperature-sensitive sample, the BH1750 measures optical clarity, and the turbidity sensor detects light scattering changes. You’ll need to adapt sample holders for non-liquid crystal materials.
Does the kit include the liquid crystal sample?
No, liquid crystal samples are not included due to their specialized chemistry and handling requirements. The kit provides the instrumentation; you’ll source a liquid crystal compound suitable for your experiment.
How do I log data for long-term experiments?
The microSD module records all sensor readings with RTC timestamps at intervals you configure. The AI companion guides you on setting up continuous logging for hours or days, so you can capture slow phase transitions reliably.
DS18B20 tracks temperature while BH1750 and turbidity together detect liquid crystal phase transitions.
