Water Level Switch is a simple electronic project made by using basic electronic components like LED, resistors, transistors. The transistor is one of the most versatile active electronics components on the planet. Almost every IC is build using transistors. Without transistors, almost every electronics appliance we use today won’t be possible. We are going to see how to make a small water level switch using a single D882 transistor. You can see the pinout of the D882 transistor in the given image. D882 pinout We can use this circuit as a simple water tank level indicator. Or we can make several of these circuits and build a tank level indicator with several levels. This circuit can be customized in any way you like. Basic Components : Let’s see what components are required for this. 1. UTSOURCE 100Ω resistors 2. UTSOURCE LED 3. UTSOURCE D882 Transistor 4. Circuit wire Tools Required: 1. Soldering Iron 2.…
