When it comes to simple DIY electronics, Arduino is the development board most chosen by beginners. One of core uses of an Arduino board is to interface sensors quickly and efficiently. In this article, we cover moisture sensors that are easily connected to an Arduino board and provide accurate readings. So check this list out and let us know your favourite arduino moisture sensor in the comments section.
10. Solu Soil Humidity Hygrometer (1.10$)
The simple moisture sensor with sensitivity adjustment option available as well to the user. The affordable sensor is ideal for anyone looking to make a small project for their garden.
9. XCSOURCE 5pcs Soil Moisture Sensor(7.99$)
This sensor has an operating voltage between 3.3V-5V and comes with its own Data Acquisition system that allows you to get processed data rapidly. The DAQ system also reduces any unwanted noise and produces a clear signal.
8. TOOGOO(R) Soil Hygrometer Humidity Detection Module(2.79$)
TooGoo’s product has long leads which allow you to move the circuitry away from the area of interest. Though this might bring its problems, having the flexibility allows you to protect the controller from weather conditions.
7. Soil Hygrometer Humidity Detection Module(4.33$)
The sensor has the soil probe dimensions of 6cm x 3cm and has leads between 15cm to 21cm. The DAQ circuitry is fitted with red & green LED’s and also an LM393 comparator chip.
6. Phantom YoYo Octopus Soil Moisture Sensor(6.77$)
This sensor has the current maximum capacity of 35mA and provides output between 0-4.2V. The sensor weighs only 0.3 ounces and is almost 8 inches long.
5. Gikfun Soil Moisture Sensor (10.98$)
Gikfun is one of the well-known suppliers of DIY products online, and their products are usually reliable. This soil moisture sensor has terrific signal conditioning and can work on both 5v and 3.3v of power input.
4. RefaXi Soil Moisture Sensor(4.99$)
The sensor comes with explicit instructions for use that help beginners to interface the product properly with the Arduino. The Refaxi product has comparatively long probes that extend for up to 10 inches.
3. Soil Moisture Meter Testing Module(6.99$)
One of the most durable sensors in market today which is well evident by its operating range that is between 2.5-6V. The sensor also comes with heavily insulated leads that prevent data loss or addition of noise.
2. Arduino compatible High Sensitivity Moisture Sensor(5.98$)
The low power device has a working current which is below 20mA, making it useful for battery operated applications. The sensor works bests at 3.3V and has a maximum output signal of 3V as well.
