Review on 🌡️ Adafruit MCP9808: High Accuracy I2C Temperature Sensor Breakout Board [ADA1782] by Eric Speers

Sensor disables +4 degrees at 3.3V and +10 degrees at 5V Works with ESP-32 or ESP-8266. I tried powering from a 3.3V pin, a separate dedicated power supply, and an active high GPIO. The sensor is attached to a piece of 4.5mm thick acrylic that separates it from the microcontroller. Even when running outdoors in sub-zero temperatures, the readings are accurate. Not impressed. The only reason it got two stars was the ease of setup.
