Best For sprinkler system: Ecowitt Garden Humidity Sensor

Buy on Amazon

The setup of the moisture sensor is really straightforward. It is easy to use and integrate into the weather system. It should measure moisture of anything, and the alarms can be set to any level. It is perfect for trees/5gal+ pots. Each gateway handles up to 8 moisture sensors, so if you plan on having more moisture sensors than 8, then you'll need more gateways. It can be setup to email you when the moisture drops below a certain point.

The benefit of the wh51 sensor, unlike the other brands, is its sensor can be kept in soil for as long as the battery last. It is easy to set up with infrequent battery changes despite the frequency of recording.

Why We Like This:

Enabling the gateway to transmit to weather services unlocks more power
Works well can tell when plants need water
Particularly useful for monitoring areas where it is impractical to use a manual tester

Best For Your next project: Is Garden Humidity Sensor

Best With multimeter: Diitao Garden Humidity Sensor

Buy on Amazon

Next on the list, we've got yet another sensor that manages to win our hearts. It's the diitao garden humidity sensor and it's widely considered as one of the best convenient sensor you can buy. 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.

Best For agriculture: V Telesky Garden Humidity Sensor

Buy on Amazon

The v telesky garden humidity sensor's material feels more premium than its price would suggest. The principle of capacitive sensing is used to detect soil moisture. It is made of a corrosion resistant material. In contrast to the normal resistive sensor, this capacitive soil moisture sensor has no adjustable switching contact. It is placed in the ground directly and measures the capacity of the earth, which changes with the humidity. It has a built-in voltage regulator chip that supports a 3.3-5.5v working environment, which means it works even on a 3.3-5.5v arduino control board.

The Capacitive soil moisture sensor, transmits data through analog signals, is more resistant to corrosion and has a long service life. It avoids the problem of being easily corroded and greatly prolongs its working life.

Best For flower pot: Almocn Garden Humidity Sensor

Buy on Amazon

Best part: almocn garden humidity sensor costs comparatively low and it is available to ship in 24 hours. This capacitive soil moisture sensor distinguishes most of the resistive sensors on the market and uses capacitive sensing to detect soil moisture. 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 avoids the problem of being easily corroded and greatly prolongs its working life. It is made of corrosion resistant material which gives it an excellent service life.
