When the soil humidity increases gradually, the resistance at the two poles of the probe gradually decreases, and V1 begins to conduct. After the current is limited by resistor R1, the LED 1 is lit. At this time, because the circuit of LED 2 is connected with diode VD1, it needs to be driven by higher voltage. Similarly, LED3 is also connected in series. Only with the humidity gradually increasing, the number of LED lights can light up more.
