The 12 Best Soil Humidity sensors (2023 reviews)

If you often find yourself confused about good sensor, gouevn soil humidity sensor should be your first option for buying. The lawn soil has a lot of clay. It is a great way to check if plants have enough moisture. It is easy to read and easy to use, and takes away the guessing about how much and when to water. The meter can be used every day and will tell you when the soil needs water.

This item works exactly how it should and it is great for persnickety plants that are difficult to care for. It reads out of the read regardless of how much moisture is in the soil. It is a must have for persnickety plants that are difficult to care for. It’s great that no batteries are needed.

Best For potted Plant: IPPINKA Soil Humidity Sensor

Buy on Amazon

The ippinka soil humidity sensor should be able to handle its purpose and duties with ease. You can be busy and don't remember when you water your plants, but this thing will remind you when it turns absolutely white it's time. It is designed and made in Japan, and is the perfect addition for various houseplants. It turns blue when moist and white when dry. All it does is wick water into the fabric that changes color to see if there’s water at the depth you place the meter.

It can be used for almost all plants that grow in soils with a certain level of moisture retention. The size and shape (and color) make it hardly noticeable in the pot, so it doesn't take away from the beauty of the plants. These make it so easy to not forget to water, or overwater.

Specially helpful not to kill plants
Perfect size for average sized house plant
Easy to use and very accurate
Great product to help you care for your ants

Best For Soil Test: WANFEI Soil Humidity Sensor

Buy on Amazon

We would, of course, be remiss if we didn't mention wanfei soil humidity sensor for regular usage. The database of plants is a bit limited when you start going outside the normal plants. This plant monitor has a temperature/light sensor, with which you can monitor and analyze the light and temperature. This plant monitor only tells the amount of sunlight and reminds you of lighting when there is not enough sunlight. It only gives you an instant reading, doesn't store data or graph it. This product uses the specific APP and so you can download it to your smartphone and connect it via bluetooth.

A long stripe sensor can help quickly identify the soil water content and tell exactly whether your plant needs watering or not. There are parameters settings for each category that can be set.

Best For Your next project: Is Soil Humidity Sensor

Buy on Amazon

Is has been making great sensor for years, thanks to a combination of clever design and appropriate materials. It is a great moisture sensor for your next project. It can be controlled (monitored) by an esp8266 wifi microcontroller. It looks like chrome plated additionally can sense acidic levels in plant soil. 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. It can send both an analog moisture level and digital trigger at a specific threshold.

The device is easy to use and connects to a Raspberry Pico. It is good for one that is permantly placed. It is compatible with arduino and raspberry pi for easy integration.

Why We Like This:

Good quality that wont corrode over time
Good investment for long term

Best Capacitive style: Hiletgo Soil Humidity Sensor

Buy on Amazon

Not everyone likes to purchase sensor for their daily usage, but the hiletgo soil humidity sensor would be an anomoly. If you are looking for a soil moisture detector you are better off with a capacitive style sensor. It works great if you are wanting it to detect a water leak. It is a simple moisture sensor that can be used to detect soil moisture, when the soil water shortage, the module outputs a high level, whereas the output is low. There's a very thin metal filament that allows the probe to sense water based on fluctuations in resistance due to the presence of water. The device will self destruct if you leave it in water for any length of time.

These sensors are good just for testing, or experimental purposes. It will plate out so you can put some conformal coating on it to help it last a bit longer in water, in the end though it is not the right part for soil moisture detection as advertised. Use this sensor to make an automatic watering device that will keep your garden of plants unmanaged.

Why We Like This:

Comparator using lm393 chip, stable job
Good for detecting a water leak
Module dual output mode, digital output is simple, more accurate analog output

Best For lawn: Saillong Soil Humidity Sensor

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate sensor. The saillong soil humidity sensor is exactly that - it's a simple sensor that hits all the right notes. These are amazing for beginning gardeners like myself who know what needs to be done but have no idea where to start. The Soil moisture sensor set with reliable and accurate sensing probes ensure accurate and immediate test results, helping you easily and quickly test the moisture of soil so that you know when watering your plants. It has a dial and 10 different color scales to clearly see the results. This happens quickly if the soil is very compact, even with houseplants.

It is lightweight and portable for gardeners, with a 6.8 inch probe for deeper soil moisture detection and a clear dial display for gardeners of most ages. The monitors can not be left in the soil, it must be removed as soon after insertion to get a reading.
