RS485 Soil Temperature, Moisture, EC Sensor for Climate Control in Greenhouses (IP68, 5-30V, Arduino Compatible)

The RS485 Soil Sensor is a highly accurate and durable solution for real-time monitoring of soil temperature, moisture, and electrical conductivity (EC). Operating within a 5-30V wide voltage range, it communicates data via the MODBUS-RTU protocol using RS485. This ensures reliable data transmission for integration with automated irrigation and climate control systems. Easily paired with an Arduino UNO and a TTL to RS485 expansion board, it offers a straightforward setup for environments requiring high precision in climate and irrigation management.

With an IP68 protection level, the soil sensor is vacuum-filled and sealed with black flame-retardant epoxy resin, ensuring resilience. Its probe, made from 316 stainless steel, is rust-proof, waterproof, and resistant to salt-alkali corrosion. It can remain buried in various soil types for extended periods, offering durability without compromising on accuracy.

The sensor features automatic temperature compensation for conductivity, maintaining measurement accuracy regardless of environmental changes. It finds application in agricultural irrigation, greenhouses, rapid soil testing, plant cultures, and scientific experiments, enhancing plant growth by optimizing growing conditions.

Maintaining appropriate soil temperature is crucial as it impacts plant growth, promoting root activity and nutrient absorption. Similarly, balancing soil moisture is essential for plant health; too little moisture leads to dehydration, while excess moisture can cause root hypoxia. Electrical conductivity, indicative of soil salinity, affects water absorption by plants. By providing data on these parameters, the RS485 Soil Sensor aids growers in ensuring optimal conditions for plant health and yield.
