DuinoTech Arduino Compatible Barometric Pressure & Temperature Sensor (I2C)

You've got a project that needs pressure or altitude data, but you're not about to wire up a full weather station for it. This DuinoTech module slots in via I2C and gives you 0.01 hPa pressure accuracy plus a built-in temperature readout at 0.1 °C resolution. Altitude comes in around 1 m accuracy, and the Arduino libraries hand you a direct altitude number so you're not doing the math yourself. It's tiny, fully calibrated out of the box, and it frees up your other pins for the rest of the build. Grab one, wire two pins, and you're reading pressure data before your coffee goes cold

• 0.01 hPa pressure accuracy with 0.1 °C temperature resolution
• Altitude readout around 1 m accuracy via included Arduino libraries
• I2C interface – only two pins needed on your microcontroller
• Fully calibrated from the factory, no trimming required
• Tiny module footprint for tight project enclosures
