無線 pH 感測器發射器 (適用於 SensorTag 的 DevPack) 參考設計
TIDA-00561
概覽
TIDA-00561 shows how to build an industrial-grade wireless pH transmitter for process control. This reference design includes a designed pH front-end which can be connected directly via its onboard connector to most pH probes used in process control. The performance data was tested and characterized (input range 0 to 14 pH, overall tested accuracy +/- 0.01 pH) to ensure compatibility with process instrumentation needs.
Because TIDA-00561 form factor and electrical connections are compatible with the TI SimpleLink™ CC2650 SensorTag ecosystem, a simple firmware update is enough to select the wireless connectivity technology: Bluetooth® Smart, ZigBee® or 6LoWPAN, among others. The firmware used for testing and characterization is Bluetooth Smart, which has the highest presence ratio in portable equipment, making testing and demonstration easier. Once you select the wireless technology for your industrial wireless network, you can start collecting data with the associated gateway, which then allows you to run analytics either on a PC or directly on the Sitara-powered BeagleBone Black.
