7Semi MCP9808 Max Accuracy I2C Temperature Sensor Breakout

7Semi MCP9808 Max Accuracy I2C Temperature Sensor Breakout

The 7Semi MCP9808 Breakout is a high-precision, low-power digital temperature sensor module based on the Microchip MCP9808. It delivers incredibly accurate ambient temperature measurements with a typical precision of $\pm 0.25^\circ\text{C}$. This board processes physical heat changes into standard digital data through its reliable $I^2C$ bus. It solves the headache of complex analog calibrations by outputting fully resolved thermal figures directly to your microcontroller. The 7Semi MCP9808 Breakout is a reliable and highly trusted foundation for climate-sensitive automation.

Features

• Exceptional Accuracy: Achieves $\pm 0.25^\circ\text{C}$ typical precision, making it perfect for medical and laboratory setups.

• Wide Operating Range: Reads temperatures safely stretching all the way from $-40^\circ\text{C}$ up to $+125^\circ\text{C}$.

• High-Resolution Readings: Captures highly granular thermal shifts with a resolution stepping down to $0.0625^\circ\text{C}$.

• I2C Multiplexing: Features adjustable address pins supporting up to 8 independent sensors on a single physical bus.

• Wide Voltage Tolerance: Interfaces cleanly with both 3.3V and 5V logic systems without external step-down converters.

Key Points

• Built-in programmable registers allow you to set custom upper, lower, and critical thermal limits.

• The physical alert pin acts as an interrupt, actively firing when your setup passes a designated safety threshold.

• The factory-calibrated Silicon Bandgap sensor maintains extreme stability over long-term deployments.

• Draws very little operating current during active conversions to protect restricted battery logs.
