The soil detector operates within a 5-30V wide voltage range and communicates data via the MODBUS-RTU protocol using RS485, ensuring reliable data transmission for integration with automated irrigation and climate control systems. It can be paired with an Arduino UNO and a TTL to RS485 expansion board for easy setup. The soil measure sensor is perfect for smart farms growing rice, corn, and soybeans, as well as greenhouse environments requiring high precision in climate irrigation management.\u003c\/p\u003e\n\u003cp\u003eThe protection level of the soil sensor is IP68, and it 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, anti-corrosion, salt-alkali corrosion resistance, and long-term electrolysis resistance. It is more affected by the soil salt content. It is small, can be buried in the soil for a long time, and is suitable for various soil types.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E38045-content1.webp?v=1791352283\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E38045-content2.webp?v=1791352283\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eThe soil sensor has an automatic temperature compensation function for conductivity, which ensures measurement accuracy no matter how the environment changes.\u003c\/p\u003e\n\u003cp\u003eIt 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.\u003c\/p\u003e\n\u003cp\u003eSoil temperature has a direct impact on plant growth. Proper soil temperatures help promote plant root growth and the ability to absorb nutrients. Generally speaking, higher soil temperature is helpful for plant growth because it can increase plant metabolism, promote nutrient absorption and transport, and increase plant microbial synthesis capabilities, thereby promoting plant growth rate and yield.\u003c\/p\u003e\n\u003cp\u003eIn addition, appropriate soil moisture helps plant roots absorb water and nutrients and maintains water balance within plant cells. If the soil moisture is too low, plant roots will be limited in absorbing water, which can lead to plant dehydration, stagnant growth or even death. Excessive soil moisture may cause hypoxia in plant roots, hinder normal respiration and nutrient absorption of roots, and thus affect plant growth and development.\u003c\/p\u003e\n\u003cp\u003eSoil electrical conductivity (EC) is the level of salt in the soil (salinity). These parameters are important indicators of soil fertility and health, and ultimately affect plants. When soil has high salt content, the salt makes it difficult for plants to absorb water, even if the moisture content in the soil is high. This condition will eventually \"burn\" the plant. Plants grow best in their preferred environment within the optimal range of soil moisture, temperature and EC levels. Growers need data on these parameters and understand what actions need to be taken to ensure plant health and higher yields.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E38045-content3.webp?v=1791352311\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eFor more detailed insights on selecting the most suitable sensor, refer to the guide on [How to Select the Best Soil Moisture Sensors for Agriculture and Research Lab].\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eWide Voltage Range: \u003c\/b\u003eSupports 5-30V power supply.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRS485 Output: \u003c\/b\u003eCompatible with Arduino and other systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAutomatic Temperature Compensation: \u003c\/b\u003eEnsures measurement accuracy regardless of environmental changes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eStainless Steel Probe: \u003c\/b\u003eDesigned for long-term burial in soil or water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eIP68 Protection Level: \u003c\/b\u003eVacuum-filled and sealed with flame-retardant epoxy resin.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E38045-content4.webp?v=1791352331\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePower supply voltage: DC5-30V\u003c\/li\u003e\n\u003cli\u003ePower consumption: 0.7W@24V\u003c\/li\u003e\n\u003cli\u003eOutput mode: RS485\u003c\/li\u003e\n\u003cli\u003eDetection parameters: Temperature, Humidity, Electrical Conductivity (EC)\u003c\/li\u003e\n\u003cli\u003eHumidity parameters\u003cbr\u003eMeasuring range: 0-100%\u003cbr\u003eResolution: 0.1%\u003cbr\u003eAccuracy: 0-50%@±2%, 50-100%@±3%\u003c\/li\u003e\n\u003cli\u003eTemperature parameters\u003cbr\u003eMeasuring range: -40°C~+80°C\u003cbr\u003eResolution: 0.1°C\u003cbr\u003eAccuracy: ±0.5°C\u003c\/li\u003e\n\u003cli\u003eEC parameters\u003cbr\u003eMeasuring range: 0-20000us\/cm\u003cbr\u003eResolution: 1us\/cm\u003cbr\u003eAccuracy: 0-10000us\/cm@±3%FS, 10000-20000us\/cm@±5%FS\u003cbr\u003eTemperature compensation: memory temperature compensation, compensation range 0-50°C\u003c\/li\u003e\n\u003cli\u003eProtection level: IP68\u003c\/li\u003e\n\u003cli\u003eProbe material: anti-corrosion special electrode\u003c\/li\u003e\n\u003cli\u003eSealing material: black flame retardant epoxy resin\u003c\/li\u003e\n\u003cli\u003eWorking temperature: -40°C~+60°C\u003c\/li\u003e\n\u003cli\u003eCable length: 2m\u003c\/li\u003e\n\u003cli\u003eSize: 123*45*15mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRS485 Soil Sensor (Temperature\u0026amp;Humidity\u0026amp;EC) x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/wiki.dfrobot.com\/sen0601\/\" target=\"_blank\"\u003eProduct Wiki\u003c\/a\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":67582793515085,"sku":"E38045-001","price":69.49,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E38045-win1.jpg?v=1791352369","url":"https:\/\/www.mlab.com.au\/products\/rs485-soil-temperature-moisture-ec-sensor-for-climate-control-in-greenhouses-ip68-5-30v-arduino-compatible","provider":"MLAB","version":"1.0","type":"link"}
