AN-2260 MSP430 Interface to LMP91050 Code Library (Rev. A)
PDF, 6.1 Mb, Revision: A, File published: May 1, 2013
The MSP430в„ў is an ideal microcontroller solution for low-cost, low-power precision sensor applicationsbecause it consumes very little power. The LMP91050 is a programmable integrated analog front end (AFE) for thermopile sensors, as typically used in nondispersive infrared (NDIR) applications. This library provides functions to facilitate the interfacing of any MSP430 device to a LMP91050.

LMP91051 NDIR CO2 Gas Detection System
PDF, 1.2 Mb, File published: May 9, 2013
This Application Note begins with an introduction to nondispersive infrared (NDIR) gas sensing. The useof the LMP91051 NDIR AFE and MSP430F55XX microcontroller to make accurate CO2 NDIR gasmeasurements is examined. Performance, power, speed, and size are compared against the traditionaldiscrete op amp system.
