These really take the guesswork out of watering. It can be used on an organic culture soil, and the stick will last for approximately 6-9 months. The small stick takes approximately 3 minutes, the medium 15 minutes, and the large 25 minutes. These will not change to blue UNTIL you water with them inserted in the soil, then they will absorb the water and turn blue.

It turns blue when moist and white when dry. It is recommended to replace the refillable core of your sustee after 6-9 months of use. It is meant for pot sizes 3.5, 4, 5 and.

• Easy to use and very accurate
• Helps you to easily identify when your plants don't hesitate to purchase
• Specially helpful not to kill plants
• Perfect size for average sized house plant

Best For Your next project: Is Soil 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.

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

Best Capacitive style: Hiletgo Soil Sensor

Buy on Amazon

Not everyone likes to purchase sensor for their daily usage, but the hiletgo soil 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.

• 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: Ecowitt Soil Sensor

Buy on Amazon

The ecowitt soil sensor's high-end materials makes sure that it ages well with use. Equipped with an advanced chip, the ECOWITT WH51 wireless soil moisture sensor collects soil moisture data within 72 seconds when totally inserted into the soil. It has a waterproof cap for soil moisture sensor. It is recommended to completely insert the sensor into the soil and keep it in the soil for 2-3 minutes to get accurate readings.

The GW1100 Gateway supports up to 8 WH51 Soil Moisture Sensors, and the channel name can be edited. It is committed to consistently meeting the quality and environment requirements. It is designed to measure soil moisture only. The EcoWITT WH51 soil moisture sensor can not directly display the soil humidity readout, which can not be used alone. These are easy to install, and they hook up through wifi.

• Is a ideal range for most plants
• Well made and fit for purpose
• Collect soil moisture data within 72 seconds when totally inserted into the soil

Best With multimeter: Diitao Soil Sensor

Buy on Amazon

The diitao soil sensor is capable of outshining several other sensor featured in this list in overall features for the price point. It's different from most of the resistive sensors on the market, using the principle of capacitive sensing to detect soil moisture. It has an on-board voltage regulator that allows it to operate over a voltage range of 33 55v and output voltage. It avoids the problem that resistive sensors are highly susceptible to corrosion and greatly extends its working life.

• Lot of satisfied buyers
• One of the new comers and featured product

Best For agriculture: Almocn Soil Sensor

Buy on Amazon

The almocn soil sensor is suitable and reliable and fits well with your daily purpose. This capacitive soil moisture sensor distinguishes most of the resistive sensors on the market and uses capacitive sensing to detect soil moisture. It avoids the problem of being easily corroded and greatly prolongs its working life. These are the real ones with the tl555 and the voltage regulator. It is possible to read the amount of real-time moisture present in the soil (for judging whether the soil is wet or dry) by linking the analog output (aout) of the module to one analog input (a0) of the arduino. It is made of corrosion resistant material which gives it an excellent service life.

• Delivers what they promise
• Good investment for long term
