Temperature to RS232 Converter (Old + New)

Posted February 8, 2012 by Chris

“About 10 times a minute the controller poles each of the three I2C temperature sensors (DS1721) for it’s current temperature. The sensors are the eight pin SMT IC’s on the back of the boards. There is one on the main circuit board. There are two more sensors on the smaller boards. One of the smaller boards is screwed into the incoming air vent and the other is screwed into the vent on a backup AC unit.”
