This device can work as soil moisture indicator . The led connected in the device will start glowing as the moisture level goes very low. The basic idea of working of the device is that, the water can conduct electricity . Two probes connected at two points Probe1 and Probe2 are dipped inside the soil. As long as the moisture level remains there, the bases of Q1 will be remain at low voltage. We can assume that Probe 1 and Probe 2 are connected with each other. As soon as the soil becomes dry, the continuity of probe1 and probe2 gets disconnected and Q1 gets turned on hence Q2 gets turn on and overall the LED D1 starts glowing.
