The two exposed prongs act as a variable resistor whose resistance changes with the water content in the surrounding soil. Wet soil conducts electricity more easily (lower resistance), while dry soil has higher resistance. The onboard circuitry converts this resistance change into a readable voltage signal. The \u003cstrong\u003eanalog output (AO)\u003c\/strong\u003e delivers a continuous voltage (typically 0-4.2V at 5V supply) that you can map to a 0-1023 range using an ADC - giving you a granular moisture percentage. The \u003cstrong\u003edigital output (DO)\u003c\/strong\u003e passes through the LM393 comparator, which compares the sensor reading against the threshold set by the potentiometer, outputting HIGH or LOW accordingly. This makes it easy to trigger relays, buzzers, or pump motors without any additional code logic.\u003c\/p\u003e\n\n\u003ch2\u003eProject Ideas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Plant Watering System:\u003c\/strong\u003e Pair with an Arduino and a 5V relay module to activate a water pump when soil dries below your set threshold - keep your plants perfectly hydrated while you're away.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmart Garden IoT Dashboard:\u003c\/strong\u003e Connect to an ESP32 or ESP8266, push moisture data to Blynk, ThingSpeak, or a custom MQTT broker, and monitor your garden remotely from your phone.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAgricultural Monitoring Network:\u003c\/strong\u003e Deploy multiple sensors across a farm field, aggregate data via LoRa or Zigbee, and build a precision irrigation system that saves water and boosts crop yield.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eGreenhouse\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eProducts ship within 1-5 days from our Bengaluru warehouse.
