Description

The Single-Chip Portable Carbon Monoxide (CO) monitor reference design is a proof of concept design that showcases the capabilities of the MSP430FG6626 microcontroller (MCU). The CO monitor demonstrates the three different approaches towards constructing a CO monitor and reveals their advantages and disadvantages. The polypotentiostat circuit, which is at the heart of a CO monitor, was constructed using discrete op-amps, integrated MSP430™ MCU op-amps and implemented using an AFE.

Features
  • Ultra-low-power design, cost effective and USB connectivity
  • LCD readout
  • Single-chip solution featured applications
  • Portable gas detectors
  • Environmental monitoring
  • Industrial gas sensing
