Moisture Content Wood Meter Kit with Arduino Uno
Build a Wood Moisture Meter with Arduino Uno – DIY Moisture Content Testing Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Waterlogged firewood? Damp lumber that warps your furniture? With this kit, you’ll build a portable instrument that reads wood moisture content in seconds. Insert the two copper nail probes into any wood surface and the Arduino converts electrical resistance to a clear percentage on the LCD. Whether you’re a woodworker checking lumber dryness, a student exploring sensor physics, or a young maker building a practical tool, this project turns a handful of components into a handy workshop gadget.
What You'll Build
A fully operational, battery-powered wood moisture meter that displays real-time moisture percentage on a 16x2 LCD. The two probes act as a resistance sensor; as the wood’s moisture content changes, the Arduino Uno maps the analog reading to a calibrated scale. You’ll have a reliable device to test firewood, plywood, or timber before your next woodworking or crafting project.
What You'll Learn
- Measure electrical resistance between two probes and convert it into moisture percentage using Arduino’s analog input
- Interface an I2C LCD display to show sensor data without complex wiring
- Calibrate a sensor system by correlating raw readings with known moisture levels for accurate measurements
- Assemble a portable breadboard instrument powered by a 9V battery – no soldering required

Who This Kit Is For
Designed for young makers and students who want a hands-on introduction to sensor electronics. It’s perfect for CBSE Class 11–12 physics projects, B.Tech ECE/EEE first-year lab work, ATL Tinkering Lab activities, and even Smart India Hackathon early prototyping. Woodworking hobbyists of any age will appreciate a custom moisture meter built with their own hands — no prior coding experience needed, just curiosity and an interest in building useful tools.
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 open your AI build companion, which gives step-by-step instructions specific to this kit. You can also message us on WhatsApp; our team will help you troubleshoot in real time.
Can this meter detect moisture in soil or other materials?
The kit is optimised for wood, where resistance changes predictably with moisture. For soil, conductivity behaves differently — check out our Soil Moisture Kit (CDN-KIT-2101), which includes a dedicated sensor for that application.
Do I need to solder anything or have prior Arduino experience?
No soldering at all. The LCD comes with a pre-soldered I2C backpack, and all connections are made with jumper wires on the breadboard. The code is pre-written and explained, so even a first-time Arduino user can complete the build.
How accurate are the moisture readings?
The default code uses a standard calibration curve that gives good relative readings across common wood types. For professional-grade accuracy, the AI companion walks you through a calibration with a reference meter, allowing ±2% precision once tuned.
Two probes measure resistance through wood. Arduino correlates to moisture percentage on LCD.
