School Projects: Moisture indicator (ANY05I)

Student Electronics Kit – Moisture Indicator

This is one of our basic pre-packed electronic kits for students. It’s a fun way to learn about electronics and is great for school projects.

Each kit includes:

• All the parts you need

• A simple circuit diagram

• Easy instructions

• Pre-wired components

• Batteries included

You might need a small screwdriver to help put it together.

About the circuit:
This kit shows how a moisture indicator works. When you touch the sensor with a slightly wet finger, it sends a signal to a transistor, which then turns on an LED light.

Other Kits in This Series:

❇ ANY00I: Alarm Circuit
A simple circuit with a battery, switch, and buzzer that works as an alarm.

❇ ANY01I: Electromagnet
A battery and switch control the flow of current through a basic electromagnet.

❇ ANY02I: Crane (Forward/Reverse)
Shows how switches can change the direction of current, making a small motor turn forward or backward.

❇ ANY03I: Two-Way Light Switch
Two switches in one circuit show how a light (like on a stairway) can be turned on or off from different places.

❇ ANY04I: Series & Parallel Circuit
Two simple series circuits connected in parallel to the battery. Shows how each circuit can be controlled separately using one power supply.
