RS485 Soil pH, Moisture, Temperature Monitoring Sensor for Hydroponics (IP68, 5-30V)

This RS485 soil temperature, humidity, and pH sensor operates across a versatile voltage range from 5 to 30V and uses the MODBUS-RTU protocol for data communication. This ensures easy incorporation into existing automated irrigation systems. Pair it with an Arduino UNO and a TTL to RS485 expansion board to simplify installation and start monitoring vital soil metrics.

Constructed with an IP68 protection rating, the sensor is vacuum-sealed with black flame-retardant epoxy resin, ensuring durability. Its probe utilizes 316 stainless steel, known for being rust-proof, waterproof, corrosion-resistant, and impervious to salt-alkali corrosion and electrolysis over time. Its compact form allows for prolonged burial in the soil, adaptable to diverse soil types.

These soil sensors find application in various scenarios like agricultural irrigation, greenhouses, and scientific experiments, aiding in measuring moisture content and temperature. Such environments benefit from maintaining ideal conditions for plant growth, vital for processes like nutrient absorption and microbial synthesis.

Soil temperature is critical for plant development, with warm soils enhancing nutrient uptake and root growth. Conversely, proper soil moisture ensures optimal water and nutrient absorption by plant roots, preventing dehydration and promoting healthy growth. The sensor effectively aids in balancing these essential factors, crucial for maximized yield.

Soil pH, a measure of acidity or alkalinity, affects nutrient availability and microbial activity. This sensor provides precise pH readings, ranging from extremely acidic to strongly alkaline levels, ensuring plants are in their optimal pH zone. Such precision is invaluable for targeted interventions to maintain plant health and productivity.
