Description
The TIDA-00800 reference design entails 4 temperature sensors along a daisy chain in a cabling environment. The sensors connect to the SensorTag development platform via the UART interface where the information can be transmitted wirelessly. The Bluetooth low energy wireless technology makes testing and demonstration easier due to its integration in most modern equipment. The form factor and electrical connections are compatible with TI SensorTag 2.0 ecosystem, allowing easy prototyping with other wireless technology (Zigbee, Wifi, sub 1GHz…), while the selected sensor allows industrial grade accuracy and resolution.
