Product details
Overview
HDC1050EVM from Texas Instruments is an evaluation module designed to characterize the HDC1050 relative humidity and temperature sensor in real-world conditions. It integrates the HDC1050 (PWSON-6 package), an MSP430F5528 microcontroller, USB interface, and configurable I²C communication. The module supports remote sensor placement via break-apart design and delivers calibrated humidity/temperature data at up to 500 Hz sampling for lab validation.
For engineers reviewing the HDC1050EVM datasheet, HDC1050EVM pinout, HDC1050EVM application, or HDC1050EVM equivalent, this page provides verified hardware configuration details, GUI-driven measurement workflows, firmware update capability, and thermal isolation guidance for accurate environmental sensing validation.
Technical Context
The HDC1050EVM implements a two-section modular architecture: a sensor section containing the HDC1050 and a microcontroller section with the MSP430F5528. Communication between sections uses I²C over a 4-wire cable routed through J1/J2 headers, with fixed HDC1050 I²C address 0x40.
Power is supplied via USB Type-A (J3), regulated to 3.3 V by an LP2985AIM5-3.3 LDO. The board includes Spy-Bi-Wire debug interface for custom firmware development and supports Sensing Solutions GUI on Windows 7/XP (64-bit only) for register-level control, streaming data capture, and statistics analysis.

FAQ
What is the primary function of the HDC1050EVM?
The HDC1050EVM is an evaluation module that enables engineers to test and validate the performance of the HDC1050 relative humidity and temperature sensor under real operating conditions. It includes the HDC1050 sensor, MSP430F5528 microcontroller, USB interface, and Sensing Solutions GUI software - all integrated to support rapid calibration verification, I²C register exploration, and high-speed environmental data streaming. The HDC1050EVM is not a production-ready sensor but a lab tool for feasibility assessment.
Does the HDC1050EVM support remote sensor placement?
Yes, the HDC1050EVM supports remote sensor placement via its break-apart mechanical design. Perforations allow physical separation of the sensor section (containing the HDC1050) from the microcontroller section. Communication between sections occurs over I²C using J1 and J2 5-pin headers and a 4-wire cable. This isolation reduces thermal influence from the MCU on temperature measurements, improving accuracy - a key feature confirmed in the HDC1050EVM User's Guide (SNAU181A).
What software is required to operate the HDC1050EVM?
The HDC1050EVM requires the Texas Instruments Sensing Solutions GUI, distributed as a Windows-only installer supporting 64-bit Windows 7 and XP. The GUI provides register-level configuration, real-time data streaming up to 500 Hz, statistical analysis, and firmware updates via TI-TXT files. No Linux or macOS support exists, and 32-bit Windows systems are explicitly unsupported per the official documentation.
Can the HDC1050EVM be used without the GUI?
Yes - the HDC1050EVM can be used without the GUI by leveraging its Spy-Bi-Wire interface to develop and flash custom firmware onto the MSP430F5528 microcontroller using Code Composer Studio. The board exposes I²C signals (SDA/SCL), power (VDD/GND), and interrupt (DRDYn, unused by HDC1050) via unpopulated J1/J2 headers, enabling integration into custom host systems. However, full out-of-box functionality (streaming, logging, register editing) requires the official GUI.
What is the I²C address of the HDC1050 on the HDC1050EVM?
The HDC1050 on the HDC1050EVM has a fixed I²C address of 0x40 (binary 1000000b), as specified in Section 2.2 of the HDC1050EVM User's Guide (SNAU181A). This address is hardwired and not configurable via external pins or registers. When communicating with the sensor via the MSP430F5528 or directly through J1/J2, the master must target 0x40 for read/write operations to the HDC1050 device.
