With a compact design and adjustable detection threshold, it enables precise soil hydration monitoring and automation, powered efficiently under 20mA. Ideal for millennial tech-savvy gardeners aiming to optimize plant care with smart, real-time feedback. ## Description Specifications: Working Voltage: DC 3.3-12V Working Current: <20mA (Output Current: <30mA) Board Size: 36x15x6mm/1.42X0.59X0.23 inch (L*W*H) Sensor Probe Length: 8.8cm/3.46 inch Sensor Pin Pitch: 5 mm Sensor Cable Length: 1.2 meters /3.94ft Sensor Connecting Port: XH2.54 2P DO Port: digital value output (DO output current is about 10mA) AO Port: analog value output For those who are not sure how to use these, we would suggest looking into how to use these online. The voltage required, analog reading, etc. Instruction: 1."+" connects power positive; "-" goes to negative. Don't connect reversely or the chip will be burnt out. There is a LED power indicator at the P mark on the board. It will be light if the module operates normally. 2.Clockwise/counter-clockwise rotate the blue potentiometer to increase/reduce the detection threshold. For example, DO outputs low level when the moisture reaches 50% now, then I clockwise rotate the potentiometer to increase the detection threshold. At this time, DO outputs a low level only when the moisture reaches a point higher than 50%. 3. If you clockwise rotate the potentiometer to an extent that the LED indicator which marked "S" is light, that means the testing threshold has been surpassed. Counterclockwise rotating to the end surpasses the threshold too. The module will not work well if the detection threshold is invalid. NOTE: The threshold adjustment only works for using the DO output. 4. The AO port on the soil humidity sensor outputs analog value(voltage), and you can acquire the real-time data via the AD port of your single-chip microcomputer(MCU). Package Included: 2x Soil Moisture Sensor Module 2x Sensor Probes Review: This product does what it says. I is easy to use to detect the moisture condition in plant soil, either to set off an alarm, turn on automatic watering, or display an analog moisture value using an Arduino or purpose-built circuitry. The down side is, that using a DC current to measure moisture drives an electrolytic action between the probes. Long-term, this can cause surface erosion and deposits on the electrodes, which degrades resistance measurements, making automatic monitoring or watering control problematic. There are several ways to overcome this: 1: Insert the probe only briefly for measurement, then remove and wipe off before the next measurement. 2: Arrange to swap probe polarity frequently, via a reversible plug, DPDT switch, relay, or similar. 3:Change your Resistance measuring method to use (Floating) Alternating Current instead of Direct Current - this requires more elaborate electronics but should enable long-term unattended monitoring. As a fun project or occasional tool, this device is handy. Quality is good enough to make a long-term automated system, if some modifications are made. Review: In today’s world of microcontrollers, there have been many inventions and designs concerning the communication over a Wi-Fi network between 2 or more gadgets. Since the appearance of the ESP8266, the Wi-Fi communication between 2 (or more) µC has never been easier. **(search for esp8266 and smartphone)** it will give information and a basic example of the NodeMCU-version of the ESP866 . All pieces necessary are available on desertcart. This wonderful piece of technology can be easily programmed in the Arduino IDE and works together with the Blynk-software. To understand and make use of it, I assume you need the basic knowledge of the Arduino µC & Arduino IDE. This purchase came with 2 of the soil moisture sensors. They can be controlled (monitored) by an esp8266 wifi microcontroller. This in turn can control your irrigation system. Using amicrocontroller, makes it extremely flexible whether you just want to keep the indications local (imagine 3 LEDs one red one yellow, and one green) that you set for each point on a defined scale. Or with the ESP 8266 to your smart phone to let you know it has reached the level. Investigate ESP8266 and smartphone for any code help ## Features - Easy to read Digital value output，this soil moisture detector outputs a low level from the DO port when the detecting humidity reaches the threshold value. Good to work with Arduino/Raspberry Pi. - Adjustable Threshold Clockwise/counter-clockwise rotate the blue potentiometer to increase/reduce the detection threshold. On-board power and signal indicators make you know the working status of the board at a glance at any time. - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076DDWDJK | | Brand | IS | | Color | Black | | Compatible Devices | Single-board computers (Arduino, Raspberry Pi) | | Control Method | App | | Customer Reviews | 4.3 4.3 out of 5 stars (72) | | Item Dimensions L x W x H | 36L x 15W x 6H millimeters | | Item Weight | 0.09 Kilograms | | Manufacturer | Icstation | | Mounting Type | Floor Mount | | Power Source | Corded Electric | | Sensor Technology | Resistive Sensor | | Voltage | 12 Volts | ## Product Details - **Brand:** IS - **Colour:** Black - **Compatible devices:** Single-board computers (Arduino, Raspberry Pi) - **Power source:** Corded Electric - **Product dimensions:** 36L x 15W x 6H millimeters ## Images ![2 Sets Resistive Soil Moisture Meter, Icstation Soil Hygrometer Sensor Test Kit with Corrosion Resistant Probe, Digital Analog Signal Output for Arduino Garden Plant Care Automatic Watering System - Image 1](https://m.media-amazon.com/images/I/61V4Nm69tbL.jpg) ## Questions & Answers **Q: Do the probes last longer then 6 months as stated. That seems very short.** A: Not sure how long they last, but they are incredibly difficult to calibrate. I stopped using them. **Q: Does this sensor also check for acidic levels in plant soil?** A: I do not know. It tests for conductivity which is a function of the soil chemistry, but I don't know if acidity is a factor. **Q: can these replace capacitive sensors that come with arduino auto watering kit?** A: Probably **Q: Is there a way to make the rods longer to reach tree roots?** A: probably not. ## Customer Reviews ### ⭐ Review *by S***O on 4 July 2023* ### ⭐⭐⭐⭐⭐ Review *by R***T on 17 January 2020* This product does what it says.
