Arduino Wireless Logging, Post Three: Mysql, PHP, and a little networking

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 …

Arduino Wireless Logging, Post One: The Idea

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 …
