LM75B Temperature Sensor

The LM75B Temperature sensor allows you to use your NXP Semiconductors LM75B (datasheet) sensor with ESPHome. The I²C Bus is required to be set up in your configuration for this sensor to work.

The LM75B is a temperature-to-digital converter using an on-chip band gap temperature sensor and Sigma-Delta A-to-D conversion technique with an overtemperature detection output.

The temperature register always stores an 11-bit twos complement data giving a temperature resolution of 0.125 °C.
