Wireless Temperature Sensor

My goal of this project was to track the temperature in different rooms in my house using multiple temperature sensors to send the data back to a raspberry pi and have the data stored historically so I could display it in charts and send alerts. As a follow up to my wireless power outlet project, I wanted to use the 433mhz receiver. I came across some wireless temperature sensors that work over 433mhz. These temperature sensors are great because they are cheap, well built, battery powered and outdoor resistant. I was surprised at how difficult it is to decode the signal coming from the temperature sensors. Read More
