The TIDA-00483 reference design demonstrates a 4-20mA current loop subsystem capable of measuring the surrounding environment and communicating the temperature, humidity, and ambient light over the loop. The small footprint 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 from the current loop power, requiring less than 3.5 mA.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
