This post is all about a temperature logger module using two sensors(LM35) and uses serial communication to log data to MySQL server. And it does so by using Arduino at the logger end and JAVA at the server. The concept is so simple that the Arduino uses LM35 (providing analog output for measured temperature) ,which is connected to one of the analogIn pin of Arduino. The sketch burned to Arduino converts the read value from the pin to corresponding temperature. And it sends the data through the serial port.…
