This Adafruit MCP9808 Precision I2C digital temperature sensor is very accurate and precise. With a typical accuracy of ±0.25°C over the sensor's -40°C to +125°C range and precision of +0.0625°C. The Adafruit MCP9808 Precision I2C digital temperature sensor works great with any microcontroller using standard i2c. There are 3 address pins so you can connect up to 8 to a single I2C bus without address collisions. Best of all, a wide voltage range makes is usable with 2.7V to 5.5V logic. Unlike the DS18B20, this sensor does not come in through-hole package; so this small sensor is placed on a breakout board PCB for easy use. The PCB includes, mounting holes and pull down resistors for the 3 address pins. There is a library for Arduino that will work with any Arduino compatible. It will be up and running in 15 minutes or less. * Simple I2C control * Up to 8 on a single I2C bus with adjustable address pins * 0.25°C typical precision over -40°C to 125°C range (0.5°C guaranteed max from -20°C to 100°C) * 0.0625°C resolution * 2.7V to 5.5V power and logic voltage range * Operating Current: 200 μA (typical) *Customers looking to resell on eBay or Amazon should contact Adafruit directly. https://elecena.pl/product/27278985/adafruit-ada1782-mcp9808-high-accuracy-i2c-temperature-sensor-breakout-board 2024-11-14 https://elecena.pl/product/27278985/adafruit-ada1782-mcp9808-high-accuracy-i2c-temperature-sensor-breakout-board 2026-07-18
