Soil Moisture Sensor Module (FC-28)

Bring your engineering projects into the natural world. The Soil Moisture Sensor Module (FC-28) is the perfect tool for introducing students to automation, resource management, and automated environmental feedback loops. By estimating volumetric water content based on the electrical resistance between two metallic probes inserted into the ground, this sensor instantly tells your microcontroller whether your soil is dry, humid, or waterlogged.

As an IIT Bhubaneswar-incubated tech ecosystem, XROBOTICS WORKS integrates this precise sensor into our Smart Agriculture and automated greenhouse curriculum lines. It is the primary element used to build Smart Irrigation Systems that switch on water pumps only when crops are thirsty. The module features a dual-output configuration (Analog output for real-world percentage scaling, and a Digital threshold output for quick, binary dry/wet interrupts). Complete with an onboard LM393 comparator chip and a sensitivity adjustment potentiometer, this 4-pin module provides a solderless, high-reliability gateway into smart crop management for PM Shri Labs and composite student labs alike.
