Capacitive Soil Moisture Sensor Arduino Code

Insert it in to the soil around your plants and impress your friends with real time soil moisture data.

Capacitive soil moisture sensor arduino code.

Soil moisture sensor arduino. Soil moisture is basically the amount content of water present in the soil. Our soil moisture sensor measures soil mositure levels by capacitive sensing rather than resistive sensing like other sensors on the market. In this tutorial we have used the waveshare soil moisture sensor.

A comparator activates a digital output when a adjutable threshold is exceeded. The soil moisture is monitored in real time. If your plant is outdoors you have to protect your electronics from getting rusted or damaged. This project is about arduino and capacitive soil moisture sensor lcd oled interfacing tutorial.

Following is the python code we use for generating moisture from the value from the capacitive soil moisture sensor measurement in the smart garden system. This can be measured using a soil moisture sensor either resistive or capacitive here we will use capacitive soil moisture sensor v1 2 this sensor measures the volumetric content of water inside the soil and. It has a fork like design which makes it easy to insert into the soil. First we read the value from the capacitance sensor note.

Glue or tape the relay module and the arduino to a nearby wall. We scale 16 bits down to 10 bits to maintain compatibility with resistive sensors the smart garden system also supports. Interfacing soil moisture sensor and arduino. It has a detection length of 38mm and a working voltage of 2v 5v.

Capacitive soil moisture sensor arduino in this tutorial you will learn how to use the capacitive soil moisture sensor v1 2 with arduino and display the soil moisture value on a 16 2 i2c lcd module. The analog output voltage boosts along with the soil moisture level increases. It is made of corrosion resistant material which gives it an excellent service life. In automatic plant watering systems the diy moisture sensor uses 2 pieces of fundue forks the diy moist level indicator is made with 5 neopixel smd5050 leds with ws2812b.

After s the soil moisture sensor into the soil near your plant. A 12volt dc water pump is controlled as the soil moisture increases or decreases below a certain pre defined value. In my case i glued it to the pot which had my. At the time we start writing the code we define 3 variables.

The soil moisture sensor measures soil moisture grace to the changes in electrical conductivity of the earth soil resistance increases with drought.
