RS485 4-in-1 Soil Moisture, Temperature, pH & EC Sensor for Smart Agriculture (IP68, 5-30V)

The versatile 4-in-1 soil sensor is meticulously crafted to assess crucial soil parameters: temperature, humidity, electrical conductivity (EC), and pH. Think of it as a weather station for your soil, offering a comprehensive data suite that empowers efficient irrigation and precise soil management. With a wide voltage power supply range from 5 to 30V and RS485 data transmission integrating the reliable MODBUS-RTU protocol, this sensor delivers rapid, accurate, and stable readings. It's seamlessly compatible with the Arduino UNO and the TTL to RS485 expansion board for a straightforward setup, serving a myriad of applications from greenhouse farming to scientific research.

This single device replaces the need for multiple sensors, simplifying your toolbox and project designs. Built to withstand the rigors of various environments, the sensor features an IP68 protection level, sealed with flame-retardant epoxy resin. Its probe, forged from 316 stainless steel, resists rust, water, and corrosion, standing up to salt-alkali corrosion and long-term electrolysis. It's so robust, it can be left buried in soil for extended periods, blending strength with sensitivity for monitoring diverse soil types.

The soil sensor incorporates an automatic temperature compensation function for enhanced conductivity accuracy. This feature ensures precise measurements regardless of fluctuating environmental conditions, making it an invaluable asset in fields ranging from agricultural irrigation to scientific experiments. The sensor's capacity to assess soil temperature and humidity aids in understanding plant growth and nutrient absorption dynamics. Meanwhile, the EC reading offers a glimpse into the soil's salinity, a key determinant of soil fertility. High salinity can impede a plant's ability to absorb water, affecting overall health.

Understanding soil pH is equally important, as it reflects the soil's acid-base balance. The sensor’s pH evaluation reveals the soil's reaction, indicating whether it's acidic, neutral, or alkaline. Such insights are pivotal for tailoring fertilization methods to optimize plant health and yield. With its extensive range of applications, this 4-in-1 soil sensor is an indispensable tool for monitoring and managing soil health effectively.
