1pcs PCT2075 11-Bit High-Accuracy I2C Temperature Sensor – QT/Qwiic Compatible with 27-Address Multi-Device Support

Key Options
11-Bit ADC for Superb-Grained Sensing:
Measures temperature from -55°C to +125°C with 0.125°C decision (11-bit output), considerably enhancing on LM75’s 9-bit (0.5°C) precision for purposes like industrial management, IoT, and wearables.
27 Distinctive I2C Addresses:
Three handle pins (A0, A1, A2) help low (0), excessive (1), or floating (F) states, enabling 27 doable addresses (3³), which eliminates handle conflicts in techniques with a number of sensors (e.g., 27 PCT2075s on a single bus vs. 8 LM75s).
QT/Qwiic & Direct I2C Connectivity:
Outfitted with STEMA QT/Qwiic connectors for solderless integration with SparkFun Qwiic/Adafruit STEMMA ecosystems, plus customary I2C pins (SCL/SDA) for direct microcontroller connection (Arduino, Raspberry Pi, and so on.).
Interrupt Pin for Threshold Monitoring:
Devoted INT pin prompts when temperature exceeds user-set excessive/low thresholds, lowering host processor load and enabling power-efficient alerting in real-time monitoring techniques.
Large Voltage Vary & Strong Design:
Operates on 2.7V–5.5V (matches microcontroller logic ranges, e.g., 5V for Arduino, 3.3V for Feather), with built-in noise immunity for secure efficiency in noisy environments.
