It is perfect for low-voltage microcontroller with both 3.3V and 5V power supply. This module includes an onboard voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V. Insert it into the soil around your plants and monitor the real-time soil moisture data. It is made of corrosion-resistant material which gives it excellent service life. This soil moisture sensor measures soil moisture levels by capacitive sensing rather than resistive sensing like other sensors on the market. This sensor measures the volumetric content of water inside the soil and gives us the moisture level as output. Here we will use Capacitive Soil Moisture Sensor v1.2. This can be measured using a soil moisture sensor either resistive or capacitive. Soil moisture is basically the amount/content of water present in the soil. This project is about Arduino and Capacitive Soil Moisture Sensor & LCD/OLED Interfacing Tutorial. 8 Video Tutorial: Interface Capacitive Soil Moisture Sensor with Arduino & LCD.7 Capacitive Soil Moisture Sensor Calibration.6 Interface Capacitive Soil Moisture Sensor with OLED Display & Arduino.5 Interface Capacitive Soil Moisture Sensor with Arduino & 16X2 LCD Display.4 Interface Capacitive Soil Moisture Sensor with Arduino.3.3 Capacitive Soil Moisture Sensor Schematic.

In this part we need to create a Class for manage serial Port in Java, for this you can see in this link the java class provide by arduino web site, where also you find the explanation, I modified a little bit that class according to what I want to do, the source code of my class is the following. Please replace the version numbers with the version you are using.Īdd a JFrame to your project and Design and interface like shown in the next figure Designing Project in Java to Show Temperature and Humidity using JFreeChartįirst create a java project in Netbeans, in your project go to Libraries folder, right click choose Add JAR/Folder and add the following libraries. read humidity and print in the serial portĦ. read temperature in celsius degree and print in the serial port The source code in arduino is not so complicated, as we can see first you need to add the library dht11.h to start to use DHT11 temperature and humidity sensor and then define the digital pin you will use to read the information from the sensor and finally read the information from dht11 sensor (temperature and humidity) and print in the serial port for further reading from C#. Arduino Source Code to get Temperature and Humidity from DHT11 In the next figure we can see the first pin is connected to pin digital 2 in arduino board, the middle one to 5v and the last one is connected to GND.ĥ. The next picture show the sketch for this project

No more than 1 Hz sampling rate (once every second)įor implement this project we will required the following materials:.

Good for 0-50☌ temperature readings ☒☌ accuracy.

Good for 20-80% humidity readings with 5% accuracy.

2.5mA max current use during conversion (while requesting data).

The technical specification of DHT11 are: In the market you will find many models, some of them have 3 or 4 pins, so be carefully and read the technical specifications. The only real downside of this sensor is you can only get new data from it once every 2 seconds. It's fairly simple to use, but requires careful timing to grab data. It uses a capacitive humidity sensor and a thermostat to measure the surrounding air, and spits out a digital signal on the data pin. The DHT11 is a basic, ultra low cost digital temperature and humidity sensor.

JFreeChart is an open-source framework library for the programming language Java, which allows the creation of a wide variety of both interactive and non-interactive charts.Ī free Java chart library. We will show the temperature in Celsius degree and Humidity in percentage using JFreeChart open source library. In this tutorial we will learn how use temperature and humidity sensor from the environment using DHT11 in Arduino and process the information in Java via serial Port.
