Soil Moisture Detection Circuit using Node MCU esp8266

| Circuit Diagram |
The soil wet device consists of 2 probes that live wont to measure the volumetrical content of water. The 2 probes permit this to labor under the soil then it gets the resistance price to live the wet price.
When there's a lot of water, the soil can conduct a lot of electricity which implies that there'll be less resistance. Therefore, the wet level are higher. Dry soil conducts electricity poorly, thus once there'll be less water, then the soil can conduct less electricity which implies that there'll be a lot of resistance. Therefore, the wet level are lower.
Connect jumper wires as per circuit diagram
Code to Execute on Arduino IDE
