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.

Our soil moisture sensor measures soil mositure levels by capacitive sensing rather than resistive sensing like other sensors on the market. At the time we start writing the code we define 3 variables. 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 comparator activates a digital output when a adjutable threshold is exceeded. Interfacing soil moisture sensor and arduino. It has a fork like design which makes it easy to insert into the soil. 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.

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 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. In my case i glued it to the pot which had my.

The analog output voltage boosts along with the soil moisture level increases. A 12volt dc water pump is controlled as the soil moisture increases or decreases below a certain pre defined value. In this tutorial we have used the waveshare soil moisture sensor. To avoid corrosion of the soil moisture sensor you a capacitive one.

This project is about arduino and capacitive soil moisture sensor lcd oled interfacing tutorial. First we read the value from the capacitance sensor note. 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. 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. We scale 16 bits down to 10 bits to maintain compatibility with resistive sensors the smart garden system also supports. The soil moisture is monitored in real time.

Glue or tape the relay module and the arduino to a nearby wall.
