-## LM75AD I2C Temperature Sensor
+## LM75AD I<sub>2</sub>C Temperature Sensor
 
 ### Features
 
 * Pin-for-pin replacement for industry standard LM75 and offers improved temperature resolution of 0.125°C and Specification of a single part over power supply range from 2.8 V to 5.5 V
 * Small 8-pin package types: SO8 and TSSOP8
-* I2C-bus interface with up to 8 devices on the same bus
+* I<sub>2</sub>C-bus interface with up to 8 devices on the same bus
 * Power supply range from 2.8 V to 5.5 V _**(Note that for use the ESP8266 you must limit this to 3.3V as the GPIO pins of the ESP8266 are not 5V tolerant)**_
 * Temperatures range from −55°C to +125°C
 * 11-bit ADC that offers a temperature resolution of 0.125°C

-R1 and R2 are pull-up resistors which are required by the I2C bus to operate properly. If you have other I2C sensors with pull-up resistors connected to the same I2C bus it's probably not necessary to have them.

 ### Hardware Configuration
 
-For connection to the ESP8266 I2C bus it is important to connect the SCL and SDA pins according to how the Sonoff firmware was configured.

-The driver must be enabled in the firmware's user_config.h file by ensuring that the USE_I2C and USE_LM75AD lines are uncommented.

 The driver currently only allows the use of a single LM75AD sensor on any of the addresses configurable through pins A0, A1 and A2 - These are usually conveniently broken out on a breakout board either as pins or as solderable joins as can be seen on the example breakout board provided in the images above.
 
-These pins need to be either tied down to GND or VCC (3.3V) and the resulting I2C address will be set during power-up according to the datasheet as follows
