Bring science to life with this hands-on DIY soil moisture sensor kit that teaches electronics while solving a real problem-knowing exactly when your plants need water. This educational kit lets you build a light-up flower indicator that responds to soil moisture levels. When the soil becomes too dry, the LED lights up, giving you a clear signal to water your plant. Perfect for beginners, students, and hobbyists, this Level 2 kit introduces essential electronics concepts including: - How an NPN transistor works as a switch - Understanding resistors and variable resistance (potentiometer) - Building a voltage divider circuit - Using conductivity to measure soil moisture ?? How It Works The “roots” act as a moisture sensor by measuring resistance in the soil. Wet soil = low resistance ? LED OFF Dry soil = high resistance ? LED ON Use the adjustable dial (potentiometer) to calibrate the moisture level for your specific plant. ?? What’s Included 1 × NPN Transistor 1 × 220? Resistor 1 × 100K Potentiometer 1 × Red LED Circuit board Tools Required (Not Included) Soldering iron Solder wire Wire cutters Phillips screwdriver
