When I got all this data logged and running, I wanted an easier way to show data than spreadsheets or queries. The end goal was actual graphs to show trends and what not. Introducing “phpgraphlib”. This is an open source piece of code built to implement charts/graphs into webpages with ease. This took a bit …

Here’s where things started to get a little more complex. At this point, I have a wireless system to transmit data from multiple nodes to a central hub (node0) which collects and shows the data via serial connection. The general idea/goal is this: Arduino Nodes send data to central node Central node is connected to …

This is the second part of the series for my Arduino wireless project I’ve been working on for a couple weeks now. You can start reading from the first post: https://aasullivan.com/?p=1146. We have the idea, now we have to build it. I have three Arduinos set up at this point in this manner: (1) Set up …

I’ve had a number Arduino systems for some time now along with a large number of RF24 wireless modules and DHT11 humidity/temperature sensors. The idea I’ve had for some time is this: Arduino with a DHT11 sensor and RF24 wireless device pull then transmit data. Data goes to secondary hub/master Arduino using an RF24 module …
