Arduino Soil Nutrient Monitoring Kit Online - TDS EC & Temperature Logger
Arduino Soil Nutrient & Temperature Mapping Kit - Uncover Nutrient Gradients with a TDS EC Probe
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 raw farmland into a data-driven experiment. With this kit, students and hobbyists build a portable monitoring station that logs TDS (total dissolved solids) and temperature at multiple soil depths, then visualizes nutrient concentration gradients on an OLED screen - a real-world tool for precision agriculture, environmental science fairs, or Smart India Hackathon prototypes.
What You'll Build
You'll assemble a battery-powered Arduino Uno system that reads TDS/EC conductivity values from a single probe inserted into different soil layers, combines them with dual-depth DS18B20 temperature data and a timestamp from the RTC, saves everything to a microSD card, and displays live readings on a 0.96-inch OLED. The result is a data logger you can carry from spot to spot, revealing how nutrients leach or accumulate across a field.
What You'll Learn
- Calibrate and interpret TDS/EC sensor data to estimate soil nutrient concentration
- Interface multiple I2C and 1-Wire sensors with Arduino without address conflicts
- Log time-stamped sensor readings onto a microSD card in CSV format for later analysis
- Design a field-ready, battery-powered measurement tool using a breadboard prototype

Who This Kit Is For
Built for CBSE Class 11-12 students working on agriculture-tech investigations, B.Tech ECE/EEE majors prototyping soil sensors for Smart India Hackathon, and ATL Tinkering Lab facilitators looking for a ready-to-assemble environmental data logger. Also fits into IIT/NIT/VIT project semesters that demand hands-on IoT in agri-science.

How do I measure nutrient gradients at multiple depths with one TDS probe?
Insert the probe into the soil at a target depth, wait for the reading to stabilize, then record the value. Repeat at different depths or locations; the RTC timestamps each measurement so you can map gradients across the field later.
Can I use this kit for hydroponic or aquaponic solution monitoring instead of soil?
Yes. The TDS EC meter works directly in water or nutrient solutions. The waterproof DS18B20 sensors can be immersed, turning this into a dual-purpose soil/water monitoring tool.
Does the kit include a battery, and how long does it last in the field?
The kit includes a 9V battery snap. You supply a standard 9V alkaline battery; it powers the Arduino and sensors for 3-4 hours of continuous logging, enough for a full field mapping session.
