Here, we discuss the plant soil moisture meters, their different types, and how to choose the right one for you.

What is a Soil Moisture Meter?

A soil moisture meter or moisture sensor measures the water content in the soil. These meters have proved very helpful for the farmers, guiding them when they should start or stop hydrating their plants. They are available in different price ranges and each of them come with additional features for specific purposes.

The market has numerous garden tools and complex variants, while a farmer can work his way out with a basic one. A few of these variants have been discussed below.

Analog Soil Moisture Meter

These do not require batteries. Although they have an ordinary design, they are outstandingly effective. Most meters still operate on the principles of the natural conduction of electricity in the soil.

A higher electrical charge accounts for a higher concentration of water. Hence analog meters have turned out to be comparatively precise in significant cases.

Batteries are not included because they’re not needed for an analog moisture meter. These devices are straightforward in design and are surprisingly effective. The probe tips will have at least two forms of conductive metal.

Any natural electrical current in the earth will be transmitted to the probe if water is present. Water is a natural conductor of electricity. More water in the soil gets registered as a higher electrical charge on the soil moisture meter. 

Digital Soil Moisture Meter

Digital meters are operated by batteries and are featured differently than analog ones. Analog meters are generally installed with probes suspected of erosion, which is not the case with digital ones. Even the hybrid soil moisture sensors are now available as digital meters.

Digital meters have several features which are not present in an analog meter. The probe portion is not subject to corrosion like an analog may be. The batteries in the digital meter provide power to the screen. They also offer a tiny electromagnetic pulse that senses moisture.

Probes are often on long cables instead of directly secured into the device. Both hybrid and basic soil moisture sensors are available as digital devices. You can charge some of them through USB cables. The USB-enabled ones can also be transmitted directly to input data on the moisture to computer software.

Wicking Soil Moisture Meter

A wicking soil moisture reader is an older device, but it is widespread in indoor houseplants. Like a wicking meter, a plant hydrometer absorbs moisture from the soil. The water is wicked upward to the fabric, changing color if the soil is moist. The minor color change is visible when the soil is dryer.

These indoor moisture readers can indicate when it’s watering time. These do not work well outside or in direct sunlight. These classical versions of what we see today were most commonly preferred indoors. The wicking meters operate by drawing moisture from the soil.

The moisture is wicked upwards to the tissue that changes color if the soil is moist. If the color change is light, the soil will be moisture content. The soli moisture meters should be kept in place and not operable outdoors or under uninterrupted sunlight.

Hybrid Soil Moisture Meter

These are the most common types available and are not merely for soil hydration. You may install them with a pH meter which is not very precise but enough to indicate an issue. Hybrid moisture reader types are prevalent. These will provide you with the most information for your money. But they’re not limited to plant hydration solely.

A garden moisture meter is one of the critical components. It may also have a sensor that reacts to light.

You may also include a pH meter. Both analog and digital versions are available in these multi-faceted devices. Digital variations may also record and display the testing time and ambient temperature.

Factors To Note While Buying Best Soil Moisture Meter

It might not seem easy until you go through the basics of crucial points required to judge the best suitable device for the purpose.


One must look for a soil moisture meter based on its functionality. Most meters measure sunlight, moisture, and pH, while others detect moisture. A multi-functional tool is always a better choice.

Ease Of Use

A soil moisture meter that provides a friendly user display without batteries makes it convenient. Although a complicated detector may indicate higher accuracy, it might be challenging to operate. It is always advisable to go for easy ones than unused ones.


The most vital element in soil moisture meters is accuracy. A faulty sensor is nothing but a waste of time and money. A meter displaying exact values with high precision is the one everyone must be on the lookout.

Few of the inexpensive probes use conductive sensing and resistance. These types of probes quickly develop rust and corrode with time. Consequently, they start giving inaccurate results on soils with different salt levels. False readings lead to actions that are not suitable for the growth of plants. It would help if you avoided this technology probe due to its short life span and inaccurate results.


Really, it does not make sense to buy probes measuring resistance and conductivity. They are not durable, and they will not last for long.


Before buying the soil moisture meter, you must check the probe’s structure, shape, and size. The structure will decide whether you can carry the probe for outdoor purposes or not. Additionally, the meter’s design determines all the purposes that will be served the meter.

It is recommended that moisture meter probes must be long and slender because they are more valuable. You can use them in various applications as compared to short and lightweight probes. They can even monitor the small potted plants with ease.
