Or do go to use be warn it rains. Because of be the circuit is simple. Follow the circuit will think use Bipolar Transistor just one only. When measure touch the moistness make the electric current flows through to pin B of Q1 get then make it works. The Relay as a result work apply the work controls electric other appliances. วงจรตรวจความชื้นของดิน วงจรง่ายๆ แต่น่าสนใจ อ่านต่อ [...] [...] Today we try to build warn the moistness or Moisture Activated better.
