DF Robot 4-in-1 Soil Sensor - RS485 MODBUS
The DFRobot 4-in-1 Soil Sensor accurately measures soil temperature, humidity, electrical conductivity (EC), and pH, making it ideal for precision agriculture, greenhouse farming, and automated irrigation systems. It uses RS485 MODBUS-RTU communication for stable, long-range data transmission and supports a wide voltage range (5-30V) for versatile compatibility with microcontrollers like Arduino. Its IP68-rated waterproof design, corrosion-resistant 316 stainless steel probes, and automatic temperature compensation ensure durability and accurate readings even in harsh environments.
This sensor enables real-time soil monitoring, optimizing water usage and improving plant growth. Its compact design allows for long-term burial, eliminating the need for multiple sensors while providing reliable and fast readings. Compatible with TTL to RS485 expansion boards, it seamlessly integrates into smart farming, scientific research, and environmental monitoring projects.
