About this item

The Adafruit PCT2075 is a precise, low-power temperature sensor breakout board designed as a drop-in replacement for the popular LM75. Featuring an 11-bit ADC, it provides more accurate temperature readings than the LM75’s 9-bit resolution. The sensor communicates via I²C and supports up to 27 unique addresses using three-state address pins, making it ideal for multi-sensor setups. It comes equipped with STEMMA QT and Qwiic connectors for easy plug-and-play use with Arduino, CircuitPython, and Raspberry Pi. With a compact design and built-in alert functionality, the PCT2075 is excellent for projects requiring reliable temperature monitoring and simple integration.
