Pressure

Pressure sensing devices measure ambient or fluid pressure and provide essential feedback for altitude estimation, weather sensing, and automation in projects. They range from compact digital barometers to small breakout boards that expose common interfaces for straightforward connection to microcontrollers and single-board computers.

These sensors suit drone payloads for altitude awareness, robotics for environmental monitoring and flow or leak detection, and education kits that demonstrate sensing concepts. Variations include absolute versus relative sensing, different output formats, and calibration options.

Key attributes include high resolution, low noise, compact form factors, and reliable digital outputs. Variations in sensor type, interface (I2C or SPI), and software support affect how seamlessly the components integrate with existing projects and toolchains.
