Today I will tell you how to use the moisture sensor to create soil tester along Nokia 5110 LCD. Before starting this project, I want to tell you about my previous project of Arduino in which you can make home made a weather station at home. In this project, we will build a soil meter with Arduino. We will use Nokia 5110 LCD for getting the result from moisture/soil sensor.
What is Moisture Sensor?
Moisture/soil sensor determines water and heat level of land surface and gives analog output signal. It is also called soil sensor. It plays a significant role in the development of weather environment, and it also called soil sensor. So we can use it for the irrigation system as well. We can make Arduino-based irrigation system that starts dripping OR water supply automatically.
Use of Moisture Sensor with Arduino:
Here we go, this is a very simple guide I made for newbies. In short how it works? The sensor can measure soil wet or dry and display quality of soil on Nokia LCD 5110. For example take a cup of dry soil dip sensor in it and see LCD screen it will show you 1-2% moisture level because the soil is dry.
Now put some water in the cup of soil and see the level of moisture. It will 90-100% because the soil is wet.
We can make Automatic irrigation system with Moisture sensor. In the future, I will make a simple guide on irrigation system project with Arduino.
You may Need!
For this project, you need some hardware see below complete list with prices.
- Arduino Board mega 2560 ( Or your choice )9$
- Soil/ Moisture sensor 2$
- Nokia 5110 LCD 4$
- Small Breadboard with some jumper wires 5$
- 5v adapter or power bank.
Now you need to connect Arduino with LCD and sensor see below for Diagram.
Connecting hardware in this project is very easy. Connect soil sensor VVC on Arduino 5V pin, GND to GND, A0 to Arduino analog o pin.
If you don’t know how to connect Nokia 5110 display screen to Arduino, I have made a dedicated guide for Nokia LCD visit here.
Source code and Library:Download
Now the final step is to upload the main code to Arduino after connecting each thing correctly. You also need to install the library for Nokia LCD.

Note: The quality of low-cost moisture sensor is not for long time use. If you want to use it for extended time I recommend must use professional quality sensor it may cost mush little bucks 😀
