I2C

contributed by Olivier de Broqueville.
The LM75A is a very easy to use and robust small I2C temperature device. It is able to measure temperature in the range of -55° to +125°. Even if working with an I2C bus, I was able to use it in a very noisy environment (Central Heating system) at distance of between 5 to 10 meters using a shielded cable (standard 4 wires alarm shielded cable) and adding a small 100nF cap. directly on the LM75A.
