Simple solar plant watering alarm circuit

Posted: 09 Mar 2016 07:13 AM PST

This is a simple Solar plant watering alarm circuit. It will sound alarms when the soil is dry. The trees have died. It the solar sell is 6V DC power supply. Thus saving convenience and does not require batteries.No noise at night. How the circuit works As circuit diagram in Figure 1 Figure 1 the circuit diagram of the Solar plant watering alarm. The main principle is that when the soil is dry, with high resistance. However, when the soil is wet with minimal resistance. Usually the wet soil will have resistance is about 6K the electricity current will flow to the probes to base of transistor Q1-2N3904 ,makes it works conducting current from the positive voltage to CE to

Fast blinking LED bike light circuit

Posted: 05 Mar 2016 12:39 AM PST

This is a fast blinking LED bike light circuit For safety when the bike at night. We use two-NPN-PNP transistor oscillator circuit and RC circuit only show on 4 LEDs use low current. We take the four LEDs to parallel because each LED use voltage about 3 – 4.5V We want this circuit for long time using so use the LED voltage is 3V only. And makes them to blinking as the LED flasher. Figure 1 Testing the LEDs in parallel. They use current about 0.077A. But we use them in switching so low Figure 2 the circuit diagram of Fast blinking LED bike light How this circuit works This is simple transistor oscillator circuit as flip-flop. We use a
