2/5pcs Capacitive Soil Moisture Sensor Module V1.2 Wide Voltage Wire Analog for Moisture Detection Garden Watering DIY

Description

Upgrade your garden, greenhouse, or indoor plant setup with the 2/5pcs Capacitive Soil Moisture Sensor Module V1.2. Designed for precise analog moisture detection, this wide‑voltage sensor delivers reliable data for automated watering systems, DIY projects, and hobbyist experiments.

Key Highlights

• **Capacitive Technology** – No corrosion‑prone metal probes; long‑lasting performance in any soil type.
• **Wide Voltage Range** – Operates from 3.3 V to 5 V, compatible with Arduino, ESP8266, ESP32, Raspberry Pi and most micro‑controllers.
• **Analog Output** – Direct voltage signal (0‑3 V) for easy integration with analog‑to‑digital converters and PID controllers.
• **Flexible Wiring** – Pre‑soldered 4‑pin header and extra wire leads for convenient mounting and prototyping.
• **Pack Options** – Choose 2‑piece or 5‑piece kits to suit single‑sensor projects or multi‑zone irrigation systems.

Why Choose This Sensor?

Traditional resistive probes corrode over time, leading to inaccurate readings. Our capacitive design measures the dielectric constant of the soil, providing stable, repeatable data even in wet or salty environments. This makes it ideal for:

• Automated garden watering systems
• Smart greenhouse monitoring
• Hydroponic nutrient management
• Educational STEM kits and Arduino tutorials
• DIY home‑automation projects

Technical Specifications

• Operating Voltage: 3.3 V – 5 V
• Output Type: Analog voltage (0‑3 V)
• Sensing Range: 0 % – 100 % soil moisture
• Response Time: ≤ 1 second
• Dimensions: 45 mm × 20 mm × 7 mm
• Connector: 4‑pin header + optional wire leads
• Temperature Range: ‑20 °C to +85 °C

Easy Integration

Connect the VCC and GND pins to your controller’s power supply, then read the analog output (A0) with any ADC channel. The sensor’s linear voltage response simplifies calibration—just map the voltage to a moisture percentage in your code.
