Arduino Lawn Irrigation Controller Kit: Log Soil Moisture & Temperature to SD with RTC Timestamps
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 1-5 days.
Overwatering wastes water; underwatering kills grass. Become a lawn scientist with two soil moisture sensors and a waterproof DS18B20 probe. Every 15 minutes, readings with RTC timestamps write to microSD — ideal for CBSE projects, B.Tech IoT assignments, or Smart India Hackathon prototypes.
What You'll Build
Assemble a breadboard rig with a 0.96" OLED showing live moisture and temperature. Data logs to microSD every 15 minutes with timestamps like “2025-04-15 14:30:00, Moisture1: 45%, Temp: 28.5°C”. Pull the card anytime and analyse patterns.
What You'll Learn
- Calibrate resistive soil moisture sensors for accurate percentage readings in Indian soil types.
- Read the DS18B20 waterproof sensor using the OneWire library and convert raw data to Celsius.
- Set up the DS3231 RTC module to stamp every log entry with date and time, even after power-off.
- Write structured sensor data to a FAT32 microSD card and create CSV files you can open in any spreadsheet.
