Capacitive Soil Moisture Sensor Arduino Code

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

Capacitive soil moisture sensor arduino code.

It has a detection length of 38mm and a working voltage of 2v 5v. If your plant is outdoors you have to protect your electronics from getting rusted or damaged. A 12volt dc water pump is controlled as the soil moisture increases or decreases below a certain pre defined value. 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. To avoid corrosion of the soil moisture sensor you a capacitive one. 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.

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. First we read the value from the capacitance sensor note. Soil moisture sensor arduino.

Interfacing soil moisture sensor and arduino. At the time we start writing the code we define 3 variables. This project is about arduino and capacitive soil moisture sensor lcd oled interfacing tutorial. Our soil moisture sensor measures soil mositure levels by capacitive sensing rather than resistive sensing like other sensors on the market.

After s the soil moisture sensor into the soil near your plant. 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. We scale 16 bits down to 10 bits to maintain compatibility with resistive sensors the smart garden system also supports.

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. Soil moisture is basically the amount content of water present in the soil. 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. In this tutorial we have used the waveshare soil moisture sensor.

It has a fork like design which makes it easy to insert into the soil.
