Frequently Asked Questions

What is the communication protocol for the LM75BTP sensor?

The LM75BTP uses a standard I2C (Inter-Integrated Circuit) two-wire serial interface. This allows for easy connection to microcontrollers like Arduino, ESP32, STM32, and Raspberry Pi using just the SDA (data) and SCL (clock) lines, along with power and ground.

What is the operating voltage range for this sensor?

The sensor has a wide operating voltage range from 2.8V to 5.5V DC. This makes it directly compatible with both 3.3V and 5V logic systems without requiring an external voltage regulator or level shifter for the power supply.

What is the temperature measurement range and accuracy?

The LM75BTP is specified to operate and measure temperatures from -55°C to +125°C. Its typical accuracy is within ±2°C, though specific accuracy under different conditions should be verified in the official NXP Semiconductors datasheet. The digital output resolution is programmable.

How do I mount and use the HWSON-8-EP package?

The HWSON-8-EP is a surface-mount device (SMD) intended for PCB assembly. The 'EP' denotes an exposed thermal pad on the bottom, which must be soldered to a corresponding PCB pad for proper heat sinking and electrical grounding to ensure accurate temperature readings and reliable operation.
