Have you ever wanted a smart monitor that not only lets you see your kids, but also texts you the temperature in their crib, so you can be certain they are comfortable? I certainly have!
That’s why I made the Raspberry Pi (RPi) Smart Baby Monitor, and I want to show you how easy it is to build yourself using Twilio, a Raspberry Pi, and a little bit of code.
Here's my son at 4 months old along with the smart baby monitor I created for him:
The Tech Stack
The IoT app we are going to create will use the Python programming language, a Raspberry Pi, a Raspberry Pi camera, a DS18B20 temperature sensor, and the Twilio SMS API:
- Python version 3.5: The language we will write our code in
- Raspberry Pi: Environment that will hold our software (code) and our hardware (peripherals)
- RPi …
Every summer, I read tragic stories of children that die because they were left in a hot car. And every summer, my heart breaks because of the senselessness of the deaths.
So I decided to build a solution.
Today, I want to show you how easy it is to build a Help! Button that a child in a hot car could press in order to alert someone that they are in danger and need assistance.
As an aside, while I was building this project, it occurred to me that children dying in hot cars is actually two problems, not one. It is two problems because:
- Toddlers have the cognitive ability to recognize they are in danger and take some action to get out of the situation.
- Babies are not capable of recognizing danger, nor capable of taking any action. So a different solution is necessary for each scenario.(I’ll tackle how …
As a new homeowner and dad of two toddlers that leave every light in the house on, I recently switched to Commonwealth Edison’s Hourly Pricing Program, which means I shifted the amount I pay for electricity from a fixed price rate to a variable rate.
Most people pay a fixed rate for the price of electricity. In northern Illinois, it’s 7.2 cents per kilowatt hour (kWh), but it’s different for different parts of the country. Many electric companies now offer the option to switch to a variable rate, which is based on the actual real-time market price of energy.
According to ComEd: “These prices vary from hour to hour and day to day according to the actual market price of power. Higher prices are most likely to occur on weekday afternoons during the summer.” Since my wife and I both work, and the kids are at daycare, we aren’t …
