Best sellerA Soil Moisture Sensor is an electronic sensor used to detect the moisture level present in soil. It is commonly used in automatic irrigation systems, smart gardening, agricultural projects, and IoT applications. The sensor measures the moisture content of the soil and provides an electrical signal that can be read by microcontrollers such as Arduino, ESP32, and Raspberry Pi. It helps determine whether the soil is dry or sufficiently moist, allowing water pumps or irrigation systems to be controlled automatically. Key Features: Detects soil moisture level Easy to use with Arduino and ESP32 Suitable for automatic plant watering systems Compact and lightweight design Useful for educational and DIY electronics projects Supports smart agriculture and IoT applications
