-2 Arduino Uno with an Xbee attached to it
Two? What does each one do?
-1 Xbee USB Explorer for receiving data.
-5 analog sensor for air quality
What kind of sensors? Are you able to get meaningful data from the sensors using the Arduino?
Sending whatever data you have from XBee to another can be as simple as Serial.print(thedata);
Your description implies that you have 3 XBees. What kind (series 1 or series 2/2.5)? How are they configured? Do they communicate?
My goal is to receive the data acquisition from the sensors and store the data into a Mysql/Access/Excell/txt database.
That won’t happen automatically. The PC will receive serial data, from the XBee that is connected to it, but you need to have some application running on the PC that collects the serial data and does something with it.
And using PHP in web monitoring.
Monitoring what on the web? And, how does that relate to collecting sensor data in a database?
Has someone tried this ? i use win 7
I’ve collected temperature and humidity data, from two sensors, using XBees to wirelessly send the the data, in a C# application, storing the data in a SQL Server database. Separately, I’ve used C# to communicate with a MySQL database. So, what you want to do is easily do-able, if you have the right skills. If you don’t, this is a great project on which to acquire them.
