🌡️ Adafruit MCP9808: High Accuracy I2C Temperature Sensor Breakout Board [ADA1782] Review

I have ordered 2 of these and both are pointing from +4 to +10 degrees Fahrenheit on that's too high isolated it from other electronics had a very accurate thermometer next to it to check the local ambient temp basically a useless board.

Bought two for computer monitoring. They work great, but if I had known I was buying two at a time I would have bought them for a little over half the money from Adafruit. Free shipping is not free.

An ideal and inexpensive way to measure temperature with Raspberry Pi. Well documented by Adafruit, complete with diagrams showing exactly how this module is configured. The MCP9808 is an incredibly small chip that is almost impossible to hand solder. This little board works great.

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.
