Best Soil Moisture Meters Of 2022 (Types & Buying Guide)

Last Updated on June 1, 2022 by Emma W. Thomas

Are you searching for reliable and dependable soil moisture meters for your garden or lawn? If the answer is yes, our best soil moisture meters review will guide you to choose the right product.

A soil moisture meter is a must-have for a gardener, homeowner, handyman or woman, and other professionals. It helps you to find out the level of moisture in the soil. With this, you can determine when your garden or lawn needs watering.

What is a Soil Moisture Meter?

A soil moisture meter is an instrument that measures the water in the top layer of soil. It can detect rising damp, moisture in the air, or soil moisture by measuring electrical conductivity. The device is usually calibrated so that it can measure relative to a specific standard at a given time and place.

A soil moisture meter can be used in agriculture, plant science, and horticulture to measure the moisture in the soil. It has two parts: a sensor that measures the soil moisture and a digital display unit.

The sensor can be placed on top of the ground or buried deep into the ground. The data obtained from these sensors will provide information about how much water is available at different depths in the soil. This will help farmers monitor their crops’ needs for water supply throughout their growth cycles.

Usually, a Soil Moisture Meter uses a 2-axis accelerometer with an ADC to measure changes in acceleration up to 50 g’s. The data obtained from this sensor will provide information about how much change has taken place in terms of weight between two points – one with and one without any objects present.

Understanding the Importance of a Soil Moisture Meter

  1. Soil moisture meters are often used to provide information on how humid or wet the soil is in an area. They provide a reliable and consistent measurement of the soil moisture content of a specific area. These sensors work by emitting a light beam through the ground, measuring the amount of light that gets blocked by the soil particles.
  2. The data from these sensors can then be used to assess how water availability is in a specific area and monitor for drought conditions. Because there is no need for extra input or energy, they are also more cost effective than other types of sensors.
  3. There has been increased interest in using soil moisture meters as part of water resource management systems, but they have also been used for agricultural purposes such as assessing crop growth and determining when irrigation should be applied to crops.
  4. Soil moisture meters help gardeners monitor how dry or wet the soil in their garden is. They can tell when it is time to water, corrective measures for plants, and monitor the effectiveness of fertilizers.
  5. A good soil moisture meter needs to be able to provide accurate readings and need to be easy for a user to read. It should also have an easy interface so that it can be used by anyone.
  6. Gardeners are increasingly turning towards these types of devices in order to manage their gardens more effectively and efficiently. They allow them to track the progress of a plant’s growth which can help them decide on what type of plant they should grow next or what type of fertilizer they should use next.

Types of Soil Moisture Meter

Soil moisture meters are used for determining water content and soil moisture in the soil. They are usually made of metal, plastic, or glass and can be used outdoors as long as there is no electrical power source and they don’t need to be connected to a computer.

Different types of soil moisture meters are available on the market. A few of them include:

1) Multi-Scale Infrared Soil Moisture Meter: It uses infrared technology to measure the water content in different layers of the ground like topsoil, subsoil, or sub-till layer. It is made of high-density plastics with LED light sources that emit invisible infrared radiation.

2) Conductivity Meter: It measures water content by measuring conductivity levels using an electrode probe on the surface that helps to optimize plant growth.

How Soil Moisture Meters Work

Soil moisture meters are a type of electronic sensor that measures the moisture content of the soil. They are usually used to measure soil for plant growth and to help determine when to water plants.

Soil moisture meters are also referred to as wet-bulb psychrometers. These sensors were first created in the 1930s by Dr. W.M. Lewis, an American scientist, and they have been widely used since then for agricultural purposes.

The most common way these sensors work is through two methods: an evaporation method and a capacitance method.

In the evaporation method, the air is passed over the sensor’s surface and it measures how much water vapor is in the air around it with different electrical voltages that correspond with different levels of humidity. In the capacitance method, a charged capacitor chip is placed at one end of a glass tube, which then determines if any water vapor has condensed on its surface due to the humidity.

How does a soil moisture meter work without batteries

Soil moisture meters work by sensing the moisture in the soil. The device is fitted with a sensor that penetrates the soil and collects data through a series of readings.

A soil moisture meter (SMM) is an instrument used to accurately measure the water content of soils, including bare ground and plants, as well as parts of other materials such as leaves or tree bark. They can be used in agriculture, horticulture or forestry.

SMMs are typically self-contained units but some can be connected to an external power source to recharge their batteries using solar or wind power. Some SMMs use a wireless connection to transmit data back to their operator.

Buyer’s Guide Of Best Soil Moisture Meters

There are thousands of soil moisture meters out there. This makes choosing one tall order. There are a lot of things to look out for when choosing a reliable soil moisture meter. Here are the most important things you need to know before you buy a soil testing kit.


If you intend to grow your crops using accurate reading, you should go for a functional moisture meter. Some meters measure soil moisture, light, and pH level while others provide just soil meter reading. It is better to go for a 3-in-1 soil moisture meter than going for a device that handles only soil moisture.

Ease of use

A simple soil moisture meter requires no battery or electricity. Don’t go for a device that needs preparation. You need something that gives instant reading without stress.


This is the most important thing when you are choosing a soil moisture meter. Read reviews like this to help make an informed choice.

Are soil moisture meters accurate?

Yes. Best branded Soil Moisture meters are accurate 99% of the time. The accuracy of the device is largely dependent upon its calibration so it is important for users to obtain as accurate a reading as possible.

Soil moisture sensors are widely used these days because they can provide accurate readings and change depending on weather conditions or seasons. They are also useful when you need to know how well your plants are doing in terms of moisture levels and how effective your irrigation system has been at watering them adequately

Soil moisture meters are a useful tool for growers and can be used to estimate plant health as they collect data on how much water there is from soil samples taken at different depths.

By using this device, farmers will have more information about how the plants need to be watered and what plants need more water than others. This way, they will know which plants need watering more often and which ones don’t seem to get enough water but require it anyways.


You can’t go wrong with a soil moisture meter if you are concerned about the growth of your plants. As such, we recommend the General tools MMD4E Digital Moisture Meter for its ultra-functionality. This tool does more than just soil test reading. It is also used to determine moisture in woods, walls, carpet, ceiling, etc. This makes it the best soil moisture meter. If you want a device specifically for soil moisture testing, we recommend the Jellas 3-in-1 Moisture Sensor Meter. Now, it is time to end guesswork on your garden with a good soil moisture meter.
