### I2C Air Temperature Thermostat (LM75A)
The LM75A is an industry-standard digital temperature sensor. The LM75A provides 9-bit digital temperature readings with an accuracy of ±2°C from –25°C to 100°C
and ±3°C over –55°C to 125°C. The LM75A operates with a single supply from +2.7 V to +5.5 V. Communication is accomplished over a 2-wire interface which operates up to 400kHz.
The LM75A has three address pins, allowing up to eight LM75A devices to operate on the same 2-wire bus. The LM75A has a dedicated over-temperature output (O.S.) with
programmable limit and hysteresis. This output has programmable fault tolerance, which allows the user to
define the number of consecutive error conditions that must occur before O.S. is activated.
