Perfect for Arduino projects
This LM75 module worked straight out of the box with my Arduino Uno. The I2C library examples made integration seamless. Readings are stable and match my reference thermometer closely.

Consistent readings over time
Been running this sensor in a greenhouse setup for three months now. No drift detected, and it handles humidity well inside the enclosure. Highly recommended for long-term logging.

Reliable and fast
Bought five of these for a classroom project. All units performed consistently. The high-speed I2C interface handles rapid polling without lag. Great value for the price.

Easy to use for beginners
As someone new to I2C sensors, this was very forgiving. The wiring is simple (just 4 pins), and online tutorials specific to the LM75 are abundant. Works great with Raspberry Pi too.

Good precision, clear documentation
Solid sensor for embedded systems. The 12-bit resolution is sufficient for my environmental monitoring station. Only minor issue was the silkscreen labeling being slightly small, but the datasheet helped.

Compact and efficient
The breakout board design saves a lot of time compared to soldering the SOIC chip manually. Power consumption is low, which is critical for my battery-powered robot.
Q: Does this come with header pins pre-soldered?
A: The standard package includes the breakout board with unsoldered header pins included in the bag, allowing you to choose between straight or right-angle mounting. Pre-soldered options may be available upon request.
Q: How do I change the I2C address?
A: The module has three address select pins (A0, A1, A2). By connecting these pins to either VCC or GND, you can configure up to 8 different I2C addresses. Please refer to the pinout diagram in the product manual.
Q: What is the maximum cable length for the I2C connection?
A: For reliable communication, we recommend keeping I2C cable lengths under 30cm. For longer distances, consider using an I2C extender or buffer chip to maintain signal integrity.
Q: Can this module operate at 3.3V logic levels?
A: Yes, the LM75 module supports an operating voltage range of 2.7V to 5.5V, making it fully compatible with both 3.3V and 5V microcontrollers.
Q: Is the sensor waterproof?
A: No, the bare breakout board is not waterproof. If you plan to use it in wet or humid environments, please enclose it in a suitable protective housing.
