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 home network and sends this data to a┬áLAMP server (Linux-Apache-Mysql-PHP)
  • The server takes this data, breaks it into a mysql statement, and pushes it into the database to log

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:

  1. Arduino with a DHT11 sensor and RF24 wireless device pull then transmit data.
  2. Data goes to secondary hub/master Arduino using an RF24 module along with an Ethernet adapter (Wiznet 5100)
  3. This master hub then pushes the data to a web server containing a mysql database to log and store the information

Simple right? Wrong.
