Featuring a corrosion-resistant nickel-plated probe, adjustable humidity threshold via potentiometer, and a high-capacity 10A relay with a built-in delay to prevent flickering, it supports up to 1500W loads. Ideal for gardeners and smart car projects, it offers reliable, automated watering with clear LED indicators for power and relay status. ## Description Instruction: Through potentiometer regulation soil humidity control valve value, can automatically on Garden, Garden automatically watering, family pot soil humidity of control, various electronic competition,, with high power following electric, can control big current device, is less than set humidity automatically started following electric sucking-in, is greater than set humidity automatically disconnect, and has delay function, solve no delay of humidity critical state following electric kept of flashing of problem, is a simple practical of soil humidity control system. Electrical parameters: Supply voltage: 12VDC input current: more than 100mALoad 250V AC or DC 30V 10A (current below this range can be used) Module description: 1. humidity detection sensor applied to soil; 2. the blue potentiometer modules are for soil moisture threshold adjustment, adjust clockwise, humidity will be under the control of the greater and turning it counterclockwise smaller; 3. because of this module with the time delay function, adjust the humidity value, about every mobility need to wait 5-8 seconds, relay changes in corresponding changes in the Green LED lights, until transferred to meet the requirements. Noted:When the sensor was triggered, the device will work. Package Included： 2*12V Soil Moisture Sensor Controller Module2* 20cm cables ## Features - Using the company's high-quality soil sensors do detect soil moisture , the surface of nickel plated , has widened the induction area can improve conductivity, prevent contact with the soil rust problems and prolong life - When two products can control a wide range of soil moisture , the corresponding threshold by adjusting potentiometer control , humidity is below the set value, start relay , while higher than the set value, the relay is disconnected - Products with the delay function , delay of 3-5 seconds , when the humidity is detected in the critical state, the relay will not blink , flicker occurs a - High-quality products using Songle relay can withstand 1500W load , to meet the requirements of most people - Products with power indicator and relay instructions ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LW14MP0 | | Best Sellers Rank | #931,578 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #505 in Automatic Irrigation Controllers | | Brand Name | HiLetgo | | Coil Voltage | 12 volts | | Connector Type | Through Hole | | Contact Current Rating | 10 A | | Contact Type | Normally Open | | Current Rating | 10 A | | Customer Reviews | 3.5 3.5 out of 5 stars (16) | | Manufacturer | HiLetgo | | Maximum Switching Current | 10 A | | Maximum Switching Voltage | 12 volts | | Minimum Switching Voltage | 12 volts_of_direct_current | | Model | 3-01-0325 | | Mounting Type | Surface Mount | | Number of Items | 2 | | Number of Packs | 2 | | Operation Mode | Automatic | | Part Number | 3-01-0325 | | UPC | 702082655863 | | Unit Count | 2 Count | | Wattage | 1500 watts | ## Product Details - **Brand:** HiLetgo - **Connector Type:** Through Hole - **Contact Type:** Normally Open - **Current Rating:** 10 A - **Mounting Type:** Surface Mount ## Images ![HiLetgo 2pcs LM393 12V Soil Moisture Relay Module Soil Moisture Sensor with Soil Moisture Probe Wires for Smart Car - Image 1](https://m.media-amazon.com/images/I/61XDBjLij6L.jpg) ## Frequently Bought Together - HiLetgo 2pcs LM393 12V Soil Moisture Relay Module Soil Moisture Sensor with Soil Moisture Probe Dupont Wires for Smart Car Arduino - Arduino Uno REV3 [A000066] - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/43015872-hiletgo-2pcs-lm393-12v-soil-moisture-relay-module-soil-moisture](https://www.desertcart.com.ar/products/43015872-hiletgo-2pcs-lm393-12v-soil-moisture-relay-module-soil-moisture) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-08*
