Texas InstrumentsGASSENSOREVM

he Gas Sensor Platform with Bluetooth low-energy (BLE) is intended as a reference design that customers can use to develop end-products for consumer and industrial applications to monitor gases like carbon monoxide (CO), oxygen (O2), ammonia, fluorine, chlorine dioxide and others. BLE adds a wireless feature to the platform that enables seamless connectivity to an iPhone® or an iPad®. Customers can easily replace the targeted gas sensor based on their application, while keeping the same analog frontend (AFE) and BLE design. The system runs on a CR2032 coin-cell battery. AFE from TI — LMP91000 — interfaces directly with the electrochemical cell. The LMP91000 interfaces with CC2541, which is a BLE system on a chip from TI. An iOS application running on an iPhone 4S® and newer generations or an iPad 3® and newer generations lets customers interface with this reference platform. Customers can use and customize the iOS application, the hardware files and firmware source code of CC2541, which TI provides as an open source. The Gas Sensor Platform with BLE provides customers with a low-power, configurable AFE and the option to integrate wireless features in gas-sensing applications. This platform helps customers access the market faster and helps differentiate from performance, power, and feature sets.
