## Description

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

## Features

- 【Soil Moisture Meter】This probe measures soil moisture using analog resistance, making it a valuable tool for plant care. It can be used in various settings, such as gardens, greenhouses, and automated watering systems.
- 【Easy to Read】This soil moisture detector produces a low signal on the DO port when the detected humidity exceeds the set threshold. It is compatible with Arduino and Raspberry Pi for easy integration.
- 【Adjustable Threshold】Rotate the blue potentiometer to adjust the detection threshold. Power and signal indicators on the board provide real-time status updates.
- 【Analog Value Output】The soil humidity sensor's AO port provides an analog voltage value that can be obtained in real-time through the AD port of your microcontroller.
- 【Corrosion Resistant Alloy Probe】A waterproof sensor probe with high corrosion resistance lasts at least 6 months in soil.

## 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.

### ⭐⭐⭐⭐⭐ Nice little moisture sensor !
*by V***O on March 2, 2020*

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 Amazon.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

### ⭐⭐⭐⭐⭐ Check Those Flowerpots
*by R***T on January 17, 2020*

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.

### ⭐⭐⭐⭐ Good quality, but heavy drift and zero instructions and missing rubber sleeves.
*by K***S on March 7, 2022*

Good quality that wont corrode over time. Was easy to use once you figure out how to use it. There is no instructions on connecting to Arduino module through Analog or exactly what the adjustment pot does.Both mine was also missing the plastic tubes that is supposed to water-proof it.. The description shows pictures and clearly says it has "Two Transparent rubber sleeves to prevent water from entering..." - these rubber sleeves are not present and missing.Also once, integrated, there is heavy drift on the readings over time.. it takes at least 5-10 minutes to reach a stable reading, so if you turn the probe off in between readings, its very inaccurate.
