MAG BEE Soil Moisture Sensor for Arduino Automatic Watering System Robot (Pack of 2) Electronic Components Electronic Hobby Kit

This pack includes 2 Soil Moisture Sensors designed for automatic plant watering systems and soil humidity detection. Ideal for Arduino and other microcontroller-based DIY electronics projects, this sensor helps detect the presence and level of moisture in soil, allowing you to automate irrigation or alert when plants need watering. It works by measuring the resistance between two probes inserted in the soil, and outputs both analog and digital signals based on the moisture level. Key Features: - Sensor Type: Soil Moisture Sensor - Output: Analog and Digital (DO/ AO pins) - Operating Voltage: 3.3V – 5V (ideal for Arduino) - Includes LM393 comparator chip for stable digital output - Adjustable threshold via onboard potentiometer - Corrosion-resistant design for long usage - Simple 3-pin interface: VCC, GND, DO/AO - Quantity: Pack of 2 sensors Applications: - Automatic plant watering systems - Soil moisture monitoring in gardens and farms - Smart gardening and home automation - School and college science and robotics projects - Compatible with Arduino, ESP8266, Raspberry Pi, and other microcontrollers Why Choose This Product? - Reliable and easy to use with plug-and-play functionality - Widely used in educational kits and smart agriculture - Dual output options for flexible project design - Trusted by hobbyists, students, and professionals Package Includes: - 2 x Soil Moisture Sensors - 2 x Signal Output Pins (AO/DO) Note: Do not leave sensor probes continuously in soil for long durations as moisture and corrosion may reduce sensor life over time. Use it for periodic measurements or connect with relay-controlled irrigation systems.
