Grove - I2C High Accuracy Temperature Sensor (MCP9808)

Speaking of Arduino temperature sensors, we tend to think of DS18B20, lm35, and other common temperature sensors. However, the MCP9808 is one of the more accurate/precise temperature sensing options with a wider operating range and precision of +0.0625°C. What's more, this temperature sensor is compatible with Arduino with its I2C communication protocol, making it a perfect choice for your temperature-sensing projects with Arduino! The Grove - I2C High Accuracy Temperature Sensor(MCP9808) is a high accuracy digital module based on MCP9808. Integrated with Microchip MCP9808 temperature sensor, it provides high accuracy & a wide range of temperature measurements from -40°C to +125°C. Unlike other sensors, you can choose the measurement resolution of this sensor, providing high flexibility for your temperature sensing applications. In addition to high-precision temperature measurements, we also offer programmable temperature alert output. We use a separate pin to output the alarm signal, you will find it so convenient to use this signal as an interruption to control other boards.
