It supports a wide voltage power supply range and communicates data via RS485 using the reliable MODBUS-RTU protocol. The sensor exhibits quick response times and delivers stable, reliable output, making it suitable for integration with an Arduino UNO R3 and a TTL to RS485 expansion board to efficiently create a test environment.\u003c\/p\u003e\n\n\u003cp\u003eThe sensor is designed with a protection level of IP68 and is vacuum-filled and sealed with black flame-retardant epoxy resin. The probe material is made of 316 stainless steel, which is rust-proof, waterproof, and resistant to corrosion, including salt-alkali corrosion and long-term electrolysis. It is small, can be buried in the soil for extended periods, and is suitable for various soil types. The sensor also features an automatic temperature compensation function for conductivity, ensuring measurement accuracy regardless of environmental changes.\u003c\/p\u003e\n\n\u003cp style=\"text-align: center;\"\u003e\u003cimg style=\"width: 560px;  \" alt src=\"https:\/\/cdn.robotshop.com\/media\/d\/dfr\/rb-dfr-1651\/img\/dfrobot-modbus-rtu-rs485-soil-moisture-temperature-ec-sensor-ip68-5-30v-desc.webp\"\u003e\u003c\/p\u003e\n\n\u003cp\u003eThis sensor is widely used in agricultural irrigation, greenhouses, flowers and vegetables, grassland and pastures, soil rapid testing, plant culture, scientific experiments, grain storage, and the measurement of moisture content and temperature of various particulate matter. Proper soil temperature promotes plant root growth and nutrient absorption, while appropriate soil moisture helps plant roots absorb water and nutrients, maintaining water balance within plant cells. Soil electrical conductivity (EC) indicates soil salinity, which affects plant water absorption and overall health. Understanding these parameters is crucial for ensuring plant health and achieving higher yields.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eNote: Ensure proper handling to avoid damage to the sensor and maintain its accuracy.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cbutton class=\"expandable-content__toggle\" aria-expanded=\"false\" aria-controls=\"main-description\"\u003e\u003cspan class=\"expandable-content__toggle-icon\"\u003e\u003c\/span\u003e\u003cspan class=\"expandable-content__toggle-text\" data-view-more=\"View more\" data-view-less=\"View less\"\u003eView more\u003c\/span\u003e\u003c\/button\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"card details_product\"\u003e\n\u003cbutton class=\"card__collapsible-button\" data-action=\"toggle-collapsible\" aria-expanded=\"false\" aria-controls=\"unique-tab-2\"\u003e\r\n\u003cspan class=\"card__title heading h3\"\u003eWhat's Included\u003c\/span\u003e\r\n\u003cspan\u003e\r\n\u003csvg focusable=\"false\" class=\"icon icon--arrow-bottom\" viewbox=\"0 0 12 8\" role=\"presentation\"\u003e\r\n\u003cpath stroke=\"currentColor\" stroke-width=\"2\" d=\"M10 2L6 6 2 2\" fill=\"none\" stroke-linecap=\"square\"\u003e\u003c\/path\u003e\r\n\u003c\/svg\u003e\r\n\u003c\/span\u003e\r\n\u003c\/button\u003e\r\n\u003cdiv id=\"unique-tab-2\" class=\"card__collapsible\"\u003e\r\n\u003cdiv class=\"card__collapsible-content\"\u003e\r\n\u003cdiv class=\"rte text--pull\"\u003e\r\n\u003cul\u003e\n\t\u003cli\u003e1x RS485 Soil Sensor (Temperature \u0026amp;
