Capacitive Soil Moisture Sensor Arduino Code

In this tutorial we have used the waveshare soil moisture sensor.

Capacitive soil moisture sensor arduino code.

If your plant is outdoors you have to protect your electronics from getting rusted or damaged. This code for a soil moisture sensor and a moist level indicator has been developed and produced by pierre pennings december 2018 this application can be used e g. Insert it in to the soil around your plants and impress your friends with real time soil moisture data. Our soil moisture sensor measures soil mositure levels by capacitive sensing rather than resistive sensing like other sensors on the market.

To avoid corrosion of the soil moisture sensor you a capacitive one. The analog output voltage boosts along with the soil moisture level increases. Glue or tape the relay module and the arduino to a nearby wall. A 12volt dc water pump is controlled as the soil moisture increases or decreases below a certain pre defined value.

We scale 16 bits down to 10 bits to maintain compatibility with resistive sensors the smart garden system also supports. At the time we start writing the code we define 3 variables. Interfacing soil moisture sensor and arduino. Capacitive soil moisture sensor contents 1 introduction 2 specification 3 tutorial 3 1 requirements 3 2 connection diagram 3 3 calibration code 3 4 calibration 3 4 1 calibration range 3 4 2 section settings 3 5 test code 4 faq introduction our soil moisture sensor measures soil mositure levels by capacitive sensing rather than resistive.

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. 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. A comparator activates a digital output when a adjutable threshold is exceeded. 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.

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. After s the soil moisture sensor into the soil near your plant. The soil moisture sensor measures soil moisture grace to the changes in electrical conductivity of the earth soil resistance increases with drought.

The soil moisture is monitored in real time. It is made of corrosion resistant material which gives it an excellent service life. Soil moisture sensor arduino. Soil moisture is basically the amount content of water present in the soil.

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.
