Soil sensing and threshold Connect the two soil probes between the sensor node and ground. Connect the sensor-node pull-up resistor between +5 V and the sensor node. Feed the sensor node to the LM358 IN+A input. Connect the sensitivity potentiometer’s outer legs to +5 V and GND, and its wiper to IN−A. Power the LM358 from +5 V and GND. Adjust the pot to set the dry/wet threshold. Outputs Use the LM358 output as the dry signal: for the wiring above, the sensor node should rise as the soil dries. Connect the dry signal to the 555 RESET input so the buzzer oscillator runs when dry and stops when wet. Configure the 555 as an astable oscillator; the existing timed-trigger arrangement won’t make the buzzer follow the dry state continuously. Connect the piezo to the 555 OUTPUT. Wire the red LED to turn on from the dry signal and the green LED to turn on when the dry signal is low. Put a current-limiting resistor in series with each LED. Use the dry signal to control the relay module; connect the pump motor through COM and N.O. so it runs only when the relay is energized. Check whether your relay module’s IN input is active-high or active-low before connecting it directly; use a transistor inverter if its polarity requires one. The saved circuit still needs rewiring and the LED resistors added. I can’t verify this analog circuit in Cirkit’s simulator because its LM358 and 555 parts have no simulation models. View less

Probes + R1 + potentiometer feed the LM358, which compares wet/dry voltage and goes high when the soil is dry. That output switches on an alarm branch (R4 → Q1 → LED + buzzer) and triggers the 555 timer (R6, C1 set ~10s run time). The 555’s output drives R7 → Q2 → relay (with D1 protection) → pump, which waters the plant for that fixed time, then stops.
