TE Connectivity’s HTU31 Humidity Sensors has Small Size, High Accuracy

TE Connectivity released the HTU31 humidity and temperature sensor, presented as one of the smallest and most accurate humidity sensors currently available. The sensor provides precision measurement, fast response time, low hysteresis, and sustained performance, even in harsh environments.

The HTU31 keeps a strict linear response curve through its humidity (0-100%) and temperature (-40° to 125°C) ranges, respectively, and its humidity die structure enables a response time of t63% in 5 sec. Even after condensation the response time is t63% in 10 sec.

Key features of the HTU31 humidity and temperature sensor include:

• Precision engineering: Designed with precision engineering, HTU31’s linear response enables optimal system performance. It keeps a strict linear response curve through humidity (0-100%) and temperature (-40° to 125°C), respectively.
• Fast response time: HTU31’s humidity die structure enables fast response time (t63% in 5 sec). Even after condensation the response time is t63% in 10 sec, enabling sustained system performance.
• High performance: HTU31 provides a specific die and IP67 rated sealing with filter options that enable sustained performance, low hysteresis and precise environment measurement even when exposed to high temperature, high humidity or condensation events.
• Digital and analog versions: The HTU31 comes in a digital and analog version. The digital version offers two I²C addresses, which facilitates monitoring humidity and temperature in two locations using a single I²C bus line.

The IP67-rated device offers filter options for sustained performance, low hysteresis, and precise environment measurement under high temperature, high humidity, or condensation events. The HTU31 comes in a digital model with two I²C addresses, and an analog version.
