LM75 Temperature Sensor: Feature, Application and Datasheet

LM75 temperature sensor includes a delta-sigma Analog-to-digital converter and digital over-temperature detector. The host can query LM75 through it The I2C interface reads the temperature at any time. This Open drain overheat output (OS) sink current When the programmable temperature limit is exceeded. The OS output operates in one of two modes, comparator or interrupt. Host control temperature Time to alarm (TOS) and hysteresisv Temperature below the alarm condition Effective (THYST). In addition, the host can read the TOS and THYST registers of the LM75. Address of LM75 Three pins are set to allow multiple devices to work On the same bus. Power-on is in comparator mode, with TOS = +80°C and THYST = +75°C are the default values. 3.0V To 5.5V supply voltage range, low supply current, and The I2C interface makes the LM75 an ideal choice for many thermal management and protection applications.

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.
