You can build a weather station with PHP, Python, a Raspberry Pi, and a DHT11 sensor to send daily summaries via SMS and email using Twilio and SendGrid APIs. The application consists of two parts: a Python script that reads humidity and temperature data from the DHT11 sensor and stores it in a SQLite database, and a PHP application that renders the stored data as HTML. To add the ability to send daily summary notifications, you need to install additional dependencies, retrieve environment variables, set up Twilio and SendGrid APIs, and create functions to send emails and SMS. Finally, you set up a cron job to run the script every day at 23:55 (or 5 minutes) to generate and send the daily summaries. Make sure the Raspberry Pi is available to the internet using ngrok to make the link in the SMS and email notifications accessible.
