Fermion: MCP9808 High Accuracy I2C Temperature Sensor

Compared to common temperature sensors like DS18B20 and LM35, the MCP9808 stands out as a highly accurate option. It offers a typical accuracy of ±0.25°C and a maximum accuracy of ±0.5°C within the -40°C to +125°C range, with a precision of +0.0625°C. The sensor comes with user-programmable registers, allowing you to select settings such as Shutdown or Low-Power modes, and set temperature Alert window and critical output limits. When the temperature goes beyond the set limits, it outputs an Alert signal. You can set the Alert output signal polarity as an active-low or active-high comparator output for thermostat operation, or as a temperature Alert interrupt output for microprocessor-based systems. These features make it perfect for complex, multi-zone temperature-monitoring applications. It has high-temperature detection accuracy, a wide temperature detection range, and is suitable for various applications including industrial freezers, food processing, personal computers, PC peripherals, and consumer electronics. Specifications include an operating voltage of 2.7 - 5.5V, a typical operating current of 200μA, user-selectable measurement resolution, and user-programmable temperature alerts. It uses an I2C communication interface, has specific dimensions and mounting hole details. Also, you can access product wiki, schematics, dimensions, and MCP9808 datasheets. The shipping list includes one Fermion MCP9808 High Accuracy I2C Temperature Sensor.

Using the Fermion MCP9808 temperature sensor is easy. First, connect the pins correctly. Connect VCC to the positive power supply, GND to the negative power supply, SCL to the clock line, SDA to the data line, and so on as described in the label. Then, power on the sensor within the operating voltage range of 2.7 - 5.5V. You can use the user-programmable registers to set different modes and temperature limits according to your needs. When the temperature goes beyond the set limits, you'll get an alert signal. Remember to handle the sensor gently to avoid physical damage. Keep it in a dry and clean environment to maintain its performance. If you want to change the measurement resolution or temperature alert settings, refer to the product documentation. Also, check the datasheets for more detailed information about its operation and performance.
