Beehive Instrumentation Project-7: Update


Built and tested multiple HTU21D’s (2 so far) with identical fixed I2C addresses using the 74HC4052 mux/demux. Now building up on a wired prototyping board. I’m also switching to a 12VDC outdoor power, since the drill batteries only last 10-12 hours under sub-arctic conditions. I will hopefully get this to the hive while the current thaw lasts.
