Summary
Digital temperature sensor LM75 with I2C interface. Provides analog output, alert functionality, and supports Fahrenheit conversion.
Description
The Texas Instruments LM75 is a digital thermometer with an I2C interface. It supports continuous temperature monitoring and alert output with configurable threshold, hysteresis, and interrupt mode. The sensor can operate in normal or shutdown mode, and temperatures can be read in Celsius or Fahrenheit. The LM75 is widely used in embedded systems for reliable thermal monitoring.

Properties
- Address (I2C) – I2C address of the sensor.
- Alert – Configurable alert conditions:
* Active Low – Boolean, sets alert polarity. * Hysteresis – Hysteresis value for alerts (default: 5°C). * Interrupt Mode – Boolean, sets alert as interrupt or comparator. * Queue Size – Number of consecutive faults before alert (default: 1). * Temperature – Alert temperature threshold (default: 80°C).
- Enabled – Enables or disables the sensor.
- In Fahrenheit – Boolean to output temperature in Fahrenheit.
- Shut Down – Boolean to enable low-power shutdown mode.
Pins
Input Pins
- Clock – Clock input for timing.
Output Pins
- Control (I2C) – I2C communication pin.
- Out (analog) – Analog output representing temperature.
