K1005 Moisture Indicator – Beginner-Friendly Soldering and Electronics KitThe Moisture Indicator kit is an excellent introduction to basic electronics and soldering for students. Designed with education in mind, the PCB features clearly labeled component positions and generously spaced solder pads, making it ideal for beginners.This simple circuit demonstrates how a transistor can function as a switch. When the sensor probes are placed in moist soil, the lower resistance allows current to flow into the transistor’s base, switching it on and lighting the LED.A hands-on way to teach conductivity, basic components, and environmental sensing. Powered by 2 AA batteries (not included). SKU: K1005 Categories: Electronic Kits, Kits Tags: diy electronics, electronic, kit, moisture, plant
