YL-69 Soil Moisture Sensor Module Kit with LM393 Comparator – Automatic Irrigation Hygrometer for Arduino & Raspberry Pi
290.00 Rs.
Keep your plants perfectly hydrated with this high-precision YL-69 Soil Moisture Sensor Module Kit. Engineered for smart agriculture, automated home gardening, and DIY IoT projects, this system accurately detects real-time volumetric water content in soil by measuring electrical resistance across its dual prongs.
The kit features a corrosion-resistant fork probe connected to a highly stable LM393 comparator driver board. It offers a dual-output interface: an Analog Output (AO) for continuous, granular moisture percentage tracking via microcontrollers, and a Digital Output (DO) that triggers a simple high/low signal when soil moisture crosses a customizable threshold (adjustable via the onboard blue potentiometer).
Key Features & Technical Specs:
Dual Output Capability: Features both Analog (AO) for precise tracking and Digital (DO) for quick trigger events.
Onboard Adjustments: Features an integrated potentiometer to easily calibrate threshold sensitivity.
Status LEDs: Built-in power indicator (PWR-LED) and digital switch output indicator (DO-LED).
Wide Compatibility: Operates seamlessly at 3.3V to 5V, making it fully compatible with Arduino, Raspberry Pi, ESP32, and STM32 systems.
Complete Kit: Includes the YL-69 fork probe, the LM393 driver module, and the necessary rainbow connecting jumper wires.
