#Session 7
##Dallas One Wire Temperature
We'll be working with Dallas One Wire Temperature Sensor: Maxim MAX31820. Details on the sesnor are here: https://www.maximintegrated.com/en/products/analog/sensors-and-sensor-interface/MAX31820.html
Review of the OneWire protocol. What kinds of devices in addtiion to temperature sensors can be used. Then focus on the Dallas OneWire sensor.
##Data Sheet Dallas OneWire 3v Temperature Sensor
##Wiring Diagrams
-
Note: the temp sensors have correct orientation. But the diagram has the tmp36 sensor labels. Need to make/find/use a more generic package in Fritzing for it.
