Best Overall: XLUX Soil conductivity Sensor

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a sensor. The xlux soil conductivity sensor is exactly that - it's a simple sensor that hits all the right notes. This little monitor is sturdily built and works like a champ. It measures hydration in plants accurately. It helps your plants grow healthy and strong. It comes with this meter, you will know that sometimes though the top of the soil looks dry, just beneath the surface it's very wet. There is a chart on the box and it lists plants in groupings and of what moisture level/zone is best. This does measure moisture content.

The limited scope of the table for determining the right moisture level for plants makes its usefulness limited. This takes all the guesswork out of deciding when to water. It is very easy to use, and results are basically instant.

• Measures soil moisture levels just fine
• Helps the prevention of over watering and root rot
• Lot of satisfied buyers

Best For Your next project: Is Soil conductivity Sensor

Buy on Amazon

The is soil conductivity sensor is the best reliable sensor on the market today. A waterproof sensor probe with high corrosion resistance lasts at least 6 months in soil. This probe measures soil moisture using analog resistance, making it a valuable tool for plant care. It can send both an analog moisture level and digital trigger at a specific threshold. It can be used in various settings, such as gardens, greenhouses, and automated watering systems.

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. This requires more elaborate electronics but should enable long-term unattended monitoring. They also make a short user manual available for download. As a fun project or occasional tool, this device is handy.

• Good quality that wont corrode over time
• Good brand reputation

Best For Water: Hiletgo Soil conductivity Sensor

Buy on Amazon

If you want nothing but a sensor that is suitable, this hiletgo soil conductivity sensor is certainly a right investment. If you are looking for a soil moisture detector you are better off with a capacitive style sensor. It is much better as a leak or water detection device. 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.

Use this sensor to make an automatic watering device that will keep your garden of plants unmanaged. It works great if you are wanting it to detect a water leak. 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. These sensors are good just for testing, or experimental purposes.

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