Looking for the best capacitive soil moisture sensor price in Bangladesh for your Arduino or ESP32 project? The Capacitive Soil Moisture Sensor V2.0 from Robo Tech Valley delivers precise, real-time soil humidity detection for smart irrigation, agriculture automation, and environmental monitoring systems. Unlike traditional resistive sensors that corrode quickly in wet soil, this advanced capacitive sensor uses non-contact moisture sensing technology to ensure long-lasting durability and consistent accuracy.
This sensor measures soil moisture levels through capacitive sensing rather than electrical resistance, which means the probe never makes direct electrical contact with the soil. The result is a corrosion-resistant design that maintains stable readings even after months of continuous use in Bangladesh’s humid climate. Whether you’re monitoring plant health in a greenhouse, building an automated watering system, or conducting soil research, this V2.0 module provides reliable data through both analog and digital outputs for maximum flexibility.
The Capacitive Soil Moisture Sensor V2.0 is fully compatible with Arduino Uno, Arduino Mega, ESP32, ESP8266, Raspberry Pi (requires ADC), and other microcontroller platforms. It operates on a wide voltage range of 3.3V to 5.5V, making it perfect for both 3.3V and 5V logic systems without level shifting. The dual output mode gives you analog voltage readings for precise moisture percentage calculations and a digital threshold output for simple on/off irrigation control. The onboard LM393 comparator chip ensures stable performance, while the adjustable sensitivity potentiometer lets you calibrate the trigger point for your specific soil type.
Engineering students at BUET, CUET, BRAC University, Daffodil International University, and North South University rely on this sensor for final year projects, IoT agriculture applications, and robotics competitions. Hobbyist makers across Dhaka, Chittagong, and Sylhet use it to build smart plant monitoring systems, automatic garden watering solutions, and environmental data loggers. Agricultural researchers and greenhouse operators in Bangladesh integrate this sensor into precision farming setups to optimize water usage and improve crop yields through data-driven irrigation scheduling.
