Capacitive Soil Moisture Sensor Arduino Code

We scale 16 bits down to 10 bits to maintain compatibility with resistive sensors the smart garden system also supports.

Capacitive soil moisture sensor arduino code.

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. A 12volt dc water pump is controlled as the soil moisture increases or decreases below a certain pre defined value. 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. Soil moisture sensor arduino.

First we read the value from the capacitance sensor note. At the time we start writing the code we define 3 variables. 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.

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. A comparator activates a digital output when a adjutable threshold is exceeded. Interfacing soil moisture sensor and arduino. In my case i glued it to the pot which had my.

Glue or tape the relay module and the arduino to a nearby wall. It has a fork like design which makes it easy to insert into the soil. This project is about arduino and capacitive soil moisture sensor lcd oled interfacing tutorial. To avoid corrosion of the soil moisture sensor you a capacitive one.

If your plant is outdoors you have to protect your electronics from getting rusted or damaged. It is made of corrosion resistant material which gives it an excellent service life. 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. After s the soil moisture sensor into the soil near your plant.

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. The analog output voltage boosts along with the soil moisture level increases. The soil moisture is monitored in real time.

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