Dual Sensor Measurement Using Single Current-Loop with FSK Modulation Reference Design
TIDA-00483: The TIDA-00483 reference design brings together several devices to create a subsystem capable of measuring the surrounding environment and communicating the temperature, humidity, and ambient light over a 4- to 20-mA current loop. The small foot print of the design contains all sensors, filters, and control circuitry to calculate and communicate the sensor data. The reference design is intended for process measurement applications in factory automation, field transmitters, and building automation. The sensors, MCU, and communication modules all run off power from the current loop, which requires less than 3.5 mA to achieve. This power configuration allows the rest of the current to be dynamically adjustable for the 4- to 20-mA loop communication protocol standard.
