Order before 12.00PM
The Soil Moisture Sensor Module is a reliable and practical solution for measuring soil moisture levels in automatic watering systems, smart agriculture projects, and DIY electronics. Designed with a waterproof and corrosion-resistant probe, this soil moisture test module ensures stable performance and extended lifespan even when continuously inserted into soil. Available from BDTronics, this module is widely used in Bangladesh for Arduino, ESP32, ESP8266, and other microcontroller-based projects.
This soil moisture sensor supports both digital (DO) and analog (AO) signal outputs, allowing flexible integration with different control systems. The onboard voltage comparator evaluates soil moisture levels and provides accurate threshold-based digital output, while the analog output delivers real-time moisture data. BDTronics supplies this soil moisture sensor module for hobbyists, students, farmers, and automation developers across Bangladesh.
