Raspberry Pi Temperature Reporting System

This is a Raspberry Pi-based temperature reporting system that reads temperature values from a DHT11 sensor and reports them to Adafruit IO. It also includes a feature to send email notifications via IFTTT when the temperature exceeds a threshold.

Prerequisites

To run this project, you will need:

• Raspberry Pi
• DHT11 temperature and humidity sensor
• Python 3 installed on Raspberry Pi
• Adafruit_DHT library
• Adafruit_IO library
• Adafruit IO account
• IFTTT account

Hardware Setup

1. Connect the DHT11 sensor to the Raspberry Pi's GPIO pin. Make sure to note down the pin number you used.

Software Setup

1. Install the required libraries:

   pip install Adafruit_DHT Adafruit_IO

2. Create an account on Adafruit IO (https://io.adafruit.com/).

3. Create a feed on Adafruit IO for storing temperature values.

4. Set up an IFTTT account and install the IFTTT app on your mobile device.

Configuration

1. Open the temperature_reporting.py file.

2. Set the following variables:

   • ADAFRUIT_IO_USERNAME: Your Adafruit IO username.
   • ADAFRUIT_IO_KEY: Your Adafruit IO API key.
   • dht_pin: GPIO pin number connected to the DHT11 sensor.
   • threshold: Temperature threshold value for triggering notifications (if desired).

3. Configure the IFTTT applet:

   • Create an applet with Webhooks as the trigger and the email service as the action.
   • Set the trigger event name to something like temperature_exceeded.
   • Set the action to send an email to the desired email address with a suitable message indicating the temperature exceeded the threshold.

Running the Project

1. Ensure the DHT11 sensor is properly connected to the Raspberry Pi.

2. Open a terminal on the Raspberry Pi.

3. Navigate to the project directory.

4. Run the Python script:

   python temperature_reporting.py

   The script will start reading temperature values from the DHT11 sensor and sending them to Adafruit IO. If the temperature exceeds the threshold, it will print a message, trigger the configured IFTTT applet, and send an email notification to the provided email address.

Customization

• You can modify the threshold value (threshold) in the temperature_reporting.py file according to your needs.
• You can customize the IFTTT applet to trigger different actions, such as sending notifications to other services or devices.
