Soil Moisture Meter, Soil Humidity Sensor, Water Sensor, Soil Hygrometer

I was able to quickly set these up to work with my indoor garden auto watering system. The key is that they work off of a simple "is their water or not" type of idea or on/off for the most part. So you put them in about as deep as you want to measure (1 inch in my case) and you set the Arduino or raspberry pi to turn on a pump when the sensor goes to zero and turn off the pump when it's at a 1 or a certain time after it's a 1.

A very good set of moisture detectors will be used as part of a plant watering system for my electronics hobby.

Used for a course project, these humidity sensors are very easy to use and program. Simple product to use and manage.

It is a good sensor and fulfills its function perfectly. I use it in analog mode, where it gives values between 0 and 1024, 1024 being the total absence of humidity.

All works and comes with cables thanks!

I use them to measure the humidity of the soil in a nursery. So far they have solved my problem.

I created a test circuit with this sensor using Arduino and it worked just fine. However, can this be used in a circuit without Arduino? Can someone please send me a link?

I wanted to set up an automatic watering system. So I bought these components, and they work very well with an Arduino UNO :)
