This circuit is an alternative to Pot plan sensor - Part 1 (link: https://everycircuit.com/circuit/5791294515052544 ).
Here, i've only made use of transistors and zener diodes.
This circuit works in conjunction with Pot plant sensor - Part 2 (link: https://everycircuit.com/circuit/5568209618731008 ).
The full circuit takes output from circuit in this circuit, without the Leds & resistors and feeds into circuit from Part 2, replacing the logic sources with the outputs from this circuit and replacing the LED in circuit 2 with a buzzer.
