In this fourth installment of AVSensors’ 10-part application note series, we shift from architecture to action—providing real-world I²C code examples for reading pressure and temperature data from our 16-bit digital sensor series. Whether you’re new to embedded systems or just need a shortcut to get your design moving, this guide offers a hands-on approach to implementing digital communication quickly and reliably. From basic multi-byte read commands to pressure alarm logic and data scaling, this application note gives you the tools to go from sensor hookup to calibrated results—no guesswork required.
This application note provides practical I²C code examples for developers integrating AVSensors' 16-bit digital pressure sensors into embedded systems. Designed to complement the broader MCT Digital Series documentation, it focuses on facilitating quick and reliable communication using the I²C protocol. Engineers will find annotated sample functions for multi-byte reads, as well as full routines for acquiring pressure and temperature data, scaling raw outputs into engineering units, and triggering alarms based on calibrated thresholds. Ideal for embedded developers and firmware teams, this note bridges theory and practice—helping you move from data sheets to deployable code with confidence
Stay Tuned for Our Fifth Release!
In the fifth installment of AVSensors’ 10-part application note series, we return to the analog world—this time with a focus on amplifying low-level millivolt signals into clean, usable 0–5V analog outputs. Ideal for integrating uncompensated or semi-compensated pressure sensors into industrial or embedded systems, this note explores practical op-amp-based solutions for signal amplification, offset correction, and rail-to-rail output design. Whether you're building a ratiometric interface or prepping signals for ADC conversion, this guide provides the circuitry and design tips you need to make low-level sensor signals behave like high-level performers
