Designed to run on a wide voltage range (3.3V–5V), these modules fit a broad family of microcontrollers, from beginner Arduino projects to more advanced hobby setups. The kit includes five sensors, each ready to deploy in multiple zones or pots, making it ideal for DIY irrigation, garden automation, and educational experiments.\u003c\/p\u003e\n\u003ch2\u003eTwo output options for flexible projects\u003c\/h2\u003e\n\u003cp\u003eEach sensor offers both digital and analog outputs, so you can choose how you monitor moisture based on your project needs:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDigital output (D0):\u003c\/strong\u003e a simple high\/low signal that fires when moisture crosses the preset threshold, useful for straightforward on\/off control.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnalog output (AO):\u003c\/strong\u003e a voltage proportional to moisture level, enabling more nuanced readings when paired with an ADC on your microcontroller.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAdjustable threshold and easy installation\u003c\/h2\u003e\n\u003cp\u003eA blue potentiometer lets you set the moisture threshold. Turning clockwise raises the threshold (requiring more moisture to trigger), while turning counterclockwise lowers it.
