Description

The TIDA-00666 TI Design enables Bluetooth Low Energy (BLE) communication powered from a 2-wire 4- to 20-mA loop. For industrial process control instruments, analog 4- to 20-mA current loops are commonly used for analog signaling, with 4 mA representing the lowest end of the range and 20 mA the highest. The TIDA-00666 reference design measures humidity and temperature and it is broadcasting the measured values with Bluetooth Low Energy. The TIDA-00666 design is loop powered and the current value on the loop is changed according to the humidity value (0% is 4mA and 100% is 20mA).

Features
  • 4- to 20-mA loop powered bluetooth low energy communication
  • 4- to 20-mA current-loop output signal
  • 8V - to 33-V input voltage range
  • 16-bit loop current resolution
  • On board humidity and temperature sensor
