I am building a set of water quality sondes using the Celsius Fast-Response, ±0.1°C Temperature Sensor (TSYS01) and the Bar02 Ultra High Resolution 10m Depth/Pressure Sensor (MS5837). I want to daisy chain sets of these two sensors together on multiple sondes but all connected through the same i2c bus. I currently have three of each sensor (and would like to add more) and am using a Sparkfun Micromod Datalogging Carrier Board with an Artemis uC.
The issue that I am having is that the datasheets say that these two sensors only have two i2c address options, making it so that I can only have two of each sensor connected to the same bus. I would like to assign new i2c addresses to any additional sensors and not be limited to the two pre-programed addresses.
Is there a set of serial commands that I can use to assign new i2c addresses to these sensors? Or is my only option to use an i2c multiplexer?
