We arrived at another Android application aimed at Arduino and Ethernet shield. With the Arduino Http LM35 app, an Arduino Mega or Uno (both tested), an ethernet shield and an LM35 temperature sensor, we can read ambient temperatures. If the shielded sensor model is used, it is possible to read the temperature submerged in water, for example.
