Soil Humidity / Moisture Sensor (New Type - Capacitive Sensor)

Overview

Monitor soil moisture levels with precision using the New Type Capacitive Soil Moisture Sensor. Unlike traditional resistive sensors, this capacitive sensor measures soil moisture without metal probes touching the soil, preventing corrosion and ensuring long-term reliability. Ideal for smart gardening, greenhouse automation, and agricultural IoT projects, this sensor is compatible with Arduino, ESP32, and other microcontrollers.

Key Features

• Capacitive sensing technology: No exposed metal probes, reducing corrosion and extending sensor lifespan.
• Corrosion-resistant: Suitable for long-term installation in soil.
• Analog output: Provides a voltage signal proportional to soil moisture, easy to read with any ADC.
• Low power consumption: Ideal for battery-powered IoT applications.
• Wide compatibility: Works with Arduino, ESP32, Raspberry Pi, and other microcontrollers.
• Easy to use: Simple wiring and code examples available.

Technical Specifications

• Operating Voltage: 3.3V – 5.5V DC
