A soil moisture meter is a hand-held device designed purposely for determining the moisture content in the soil so as to give a farmer or gardener a good idea of how well to transform the soil to best suit the needs of the type of plants they plan to grow.
Many soil moisture meters utilize pin sensors to establish the moisture content in the soil. The tip of a soil moisture meter consists of two metal probes that are inserted into the soil.
Once inserted in the soil, the meter sends electrical currents into the soil upon which the moisture in the soil acts as a conductor to pass the electrical current between the two pins.
It basically uses the electrical conductivity of water in gauging the level of moisture in the soil. The higher the electrical current, the more the amount of moisture in the soil.
It usually comes with a gauge with colored marks that gives generalized moisture readings ranging from dry, and moist to wet or just dry and wet.
In this article, we will walk through the top 6 best soil moisture meters for plants in 2022.
Now, let’s get started.

The Sonkir MS02 3-in-1 Soil Moisture Meter is arguably one of the best soil moisture meters available on the market today. It’s a simple, very effective, and reliable device that’s not only highly affordable but offers more than just measuring soil moisture content.
To start off, the unit is pretty well constructed with the main housing consisting of a thick, high-grade that can withstand harsh outdoor conditions. The two probes are also quite sturdy and not likely to bend easily even with regular use.
They have sharp tips that will allow them to penetrate different types of soils without requiring a lot of effort. It’s something that’s certainly going to serve you for a longer period of time.
The whole unit is really compact and lightweight weighing only 2 ounces, so it’s very portable and easy to carry out. Combined with the solid, durable construction, it’s ideal for both outdoor and indoor use. You can use it in farms, lawns as well as gardens.
However, what makes this Sonkir MS02 meter really stand out is its 3-in-1 design. You can use it to determine the moisture and pH level of the soil as well as the sunlight intensity which are three of the most important conditions that affect soil quality and plant growth.
The major highlight of this design is the use of double-needle detection technology which is a highly effective technology that strongly enhances the accuracy and speed of detecting and measuring soil moisture and PH levels.
The unit uses a copper and aluminum probe each 7.9 inches long. With just 2 to 4 inches deep into the soil, you get precise moisture reading on the scale.
The moisture sensor is positioned right next to the tip of the cooper probe, so it’s able to deliver accurate moisture readings at various depths as well. It has a range of 1 to 10 with color codes to denote dry, moist, and wet moisture levels.
It measures the PH levels in the soil quite well with the sensor located slightly above the moisture sensor on the aluminum probe. It can measure the PH from 3.5 to 8 which is a fairly decent range that will help you know if your soil PH needs improvement.
The light sensor functions well too and although it will not give you cumulative readings, it gives pretty accurate measurements at the time of reading. You will need to take readings throughout the day so as to know the amount of light your garden gets.
Another commendable thing about this Sonkir meter is the fact that the needle gauge reacts quickly once you insert the probes into the soil. You don’t need to wait more than 10 minutes. It responds instantly when measuring any of the three conditions.
The unit itself is simple to operate. The functions and features are easy to use and understand. The readings are projected on a three-way scale with the moisture content and pH scales color coded for easy reading.
It’s a straightforward device. You just need to toggle the switch and select the function you want to measure and drive the probes into the soil to get the readings. That’s all.
Now the best part is that you will not have to change batteries every other time because no batteries are needed to run this moisture meter. It is solar powered which makes it highly convenient plus you can use it in almost any soil condition.
The only minor gripe is that the pH scale cannot indicate below 3.5. Furthermore, you can’t leave probes in the soil for a long period of time as they may rust. Other than that everything is amazing.
To sum it all up, the Sonkir MS02 is a versatile unit that will deliver accurate results much faster whether measuring moisture content, pH level, or sunlight intensity. It really strikes a perfect balance between quality and value for money.
If you are looking for an affordable, durable and reliable moisture meter that can help you to better understand and improve the condition of your soil, then we would absolutely recommend this one.

You just need to insert the probe into the soil for about 3 to 4 inches to get your reading. Although it uses a single probe, the meter will deliver a relatively accurate measurement which it makes ideal for the average home gardener.
The unit provides moisture content readings on a scale of 1 to 10 and has an additional color-coded reading system to give you a more generalized state of your soil’s moisture content.
Levels 1-3 denoted by a red color represent dry soil, 4-7 denoted by a green color represents moist soil while wet soil falls in the 8-10 level denoted by a blue color code. Therefore, it allows you to easily gauge the condition of your soil and take the appropriate action.
If you only want to test for moisture, then this is a hassle-free unit that you will certainly like. It will precisely register virtually all soil no matter how wet or dry the ground is.
The large dial, including the color-coded reading system, makes the entire process of using and knowing the soil’s moisture levels quite straightforward.
Furthermore, a detailed description of the best moisture condition for various plants has been included on the back part of the package.
Therefore, apart from just measuring the moisture, you will have the necessary information to help you utilize the readings so as to achieve the optimal moisture levels required for your plants to grow strong and healthy.
The unit weighs around 0.8 ounces which makes it the lightest soil moisture meter we’ve reviewed. It’s very compact too and with the quality construction, you can effectively use it indoors as well as outdoors.
Another big plus is that like the Sonkir MS02, no batteries need to operate this meter. It’s that cost-effective and convenient. However, same as the MS02 and most other soil moisture meters, this too cannot be left in the soil for a long time as it’s likely to rust.
All in all, for a simple and reliable way of determining moisture level in the soil only, the XLUX T10 is an option worth considering. It’s a very basic and inexpensive device but works as well as most other soil moisture meters within the same range.
