LM75 Temperature Sensor Module Description

LM75x Digital Temperature Sensor IC

The LM75 is an industry-standard digital temperature sensor with an integrated Sigma-Delta analog-to-digital converter and I2C interface. The LM75 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.

How to Use the LM75 Temperature Sensor Module

LM75 Temperature Sensor Module consists of five pins i.e. VCC, GND, OS, SCL, and SDA. This module is pin-compatible with Banana Pi so you can directly mount it on Banana Pi. The internal circuit diagram of this module is given below. SCL and SDA pins are connected through 4.7K ohm pull-up resistors.
