Overview

The HDC3020EVM evaluation module (EVM) enables designers to evaluate the operation and performance of the HDC3020 relative humidity and temperature sensor. The EVM hosts an MSP430F5528 microcontroller (µC) as well as the HDC3020. The µC is used to control the HDC3020 and communicate with a host PC through a USB port. The EVM is designed to be broken into two sections if desired. The perforation allows the user to disconnect the HDC3020 for flexibility in their evaluation.

Features
  • Streaming relative humidity and temperature measurements
  • Data logging
  • USB plug-and-play
  • Detachable sensor section for prototype remote operation
