Hi,
I recently followed a guide linked below to show me how to log temperature coming form a TMP102 sensor
http://bildr.org/2011/01/tmp102-arduino/
It was a fantastic guide and worked perfectly with the provided code. I was wondering if anyone could advise me on how to add another two of these sensors so i get 3 temp readings.
Thankyou
I think the I2C bus only allows one of each device per bus because of the hardware addressing - so you'll need 3 I2C busses but the Arduino doesn't have hardware support for this. A software I2C library is probably what you need to allow more busses.
According to the datasheet:
The TMP102 features an address pin to allow up to four devices to be addressed on a single bus. Table 12 describes the pin logic levels used to properly connect up to four devices.
Just look at Table 12, and wire up your extra devices appropriately.
