IOT based Temperature Monitoring System using Arduino
Anyone who wants to remotely monitor the temperature data can use the IOT based temperature monitoring system using the Arduino project. Users can then take the necessary actions depending on the real-time as well as historic IOT data provided by this project. Arduino reads the temperature data from the sensor and then sends it to an IOT cloud platform.
IOT based temperature monitoring system with SMS alert
We have also added features, such as setting up thresholds for temperature alerts and controlling external devices based on temperature conditions with the help of a Relay. Also, we have added a feature of SMS alerts. The user receives an SMS alert whenever the temperature crosses a threshold level.
Hardware components used in the IOT based Temperature Monitoring System are:
Arduino Uno board
DHT11 Temperature sensor
SIM900 GSM modem
Relay and Buzzer
LCD Display
The data output pin of the DHT11 temperature sensor is connected to the analog input pin of the Arduino Uno board. We have connected the GSM modem to the serial pins (RX & TX) of the Arduino Uno board. Other I/O pins of Arduino are connected to LCD, Buzzer, and Relay.
IOT Dashboard for IOT temperature monitoring
On the IOT website, this historical temperature data is shown in a graphical format. The Arduino publishes the temperature data to the IoT platform at regular intervals. Users can access the IoT platform website’s dashboard or web interface to visualize the temperature values in real-time. Users can also setup up notifications or email alerts if the temperature exceeds certain predefined thresholds. This way users can take timely action if necessary.
Software used in IOT based temperature monitoring system
Arduino IDE is used to write the Programming of the IOT temperature monitoring project. It is also used to download the program in the Arduino. We also have to install the necessary libraries for the temperature sensor.
Eagle software is used to design the PCB layout of the IOT temperature monitoring project.
Block diagram of the project:
The implementation of IoT based temperature monitoring system using Arduino opens up a world of possibilities for remote monitoring of temperature conditions. This system provides real-time temperature data and enables us to make informed decisions based on that information. Whether it’s monitoring the temperature in a greenhouse, forest, server room, or home, this project demonstrates the potential of IoT and Arduino in creating smart and connected environments.
Applications of the IOT based temperature monitoring project:
Industrial Monitoring: IoT temperature monitoring systems are used in industrial environments to monitor the temperature of machinery, equipment, and processes. It helps prevent overheating and detect abnormalities that may indicate potential failures or malfunctions.
Environmental Monitoring: IoT temperature monitoring systems are used in environmental monitoring applications to track temperature variations in natural habitats, agricultural fields, and climate-sensitive areas.
Smart Homes: IoT temperature monitoring systems can be integrated into smart home setups, allowing homeowners to monitor and control the temperature of individual rooms or zones. It enables energy-efficient heating and cooling, remote temperature adjustments, and intelligent automation based on occupancy or time schedules.
Data Centers: Data centers require precise temperature control to prevent equipment overheating and ensure optimal performance. IoT temperature monitoring systems provide real-time monitoring of server room temperature, triggering alerts and actions if temperature thresholds are exceeded, thereby minimizing the risk of equipment failures and downtime.
