mq135 Gas Sensor Sending Data to mysql database using xampp

hello,, i would like to ask if how could i send data of gas value into my database?? im using arduino r3, ethernet shield and mq135 gas sensor.. thank you so much

The simplest and safe (in term of database) way is:

  • Arduino: reads data from sensor
  • Arduino: makes HTTP request to WebServer (include the sensor data)
  • Webserver (PHP code): reads the sensor data from HTTP request and update to database

thank you so much, but how can i do a php code reads the sensor data from HTTP request and update to database and makes HTTP request to WebServer (include the sensor data).?
