Description

The HTU31V from TE Connectivity is a fully integrated analog sensor designed for demanding environmental monitoring. It combines a capacitive humidity sensing element with a band-gap temperature sensor, delivering calibrated analog voltage outputs proportional to relative humidity and temperature. The sensor’s thermally conductive epoxy encapsulation ensures stable performance and protects the MEMS die from environmental contaminants.

Engineered for reliability across a broad industrial temperature span, the HTU31V features fast response times and low hysteresis. Its simple analog interface eliminates the need for complex digital communication protocols, making it ideal for direct connection to microcontrollers with ADC inputs or legacy analog control systems. The PTFE-insulated leads provide excellent chemical resistance and mechanical durability for long-term installations.

Frequently Asked Questions

What is the output signal type of the HTU31V sensor?

The HTU31V provides analog voltage outputs for both temperature and humidity measurements. This allows for direct interfacing with microcontroller analog-to-digital converter (ADC) pins or analog signal conditioning circuits without requiring digital communication protocols like I2C or SPI.

What is the operating voltage range for the HTU31V?

The sensor operates from a single DC power supply between 3.0V and 5.5V. This range makes it compatible with common 3.3V and 5V logic systems found in industrial controllers, data loggers, and embedded development platforms like Arduino or Raspberry Pi (with appropriate level shifting if needed).

How should the HTU31V sensor be mounted or handled?

Due to its tiny DFN-6 package and exposed leads, careful handling is required. It is designed for surface mounting (SMD) onto a printed circuit board. The PTFE-insulated leads provide some strain relief, but the sensor body should be protected from direct condensation, dust, and mechanical stress in the final application for optimal longevity.
