Product Overview

The HTU21D is a new digital Humidity Sensor with temperature output. Setting new standards in terms of size and intelligence. This sensor provides calibrated, linearized signals in digital, I²C format. The digital humidity sensor is dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed. Direct interface with a microcontroller is made possible with the module for humidity and temperature digital outputs. These low power sensor is designed for high volume and cost sensitive applications with tight space constraints. Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip which can be read out by command. Low battery can be detected and a checksum improves communication reliability. The resolution of these digital humidity sensors can be changed by command (8/12-bit up to 12/14-bit for RH/T).
  • Full Interchange-ability with No Calibration Required in Standard Conditions
  • Instantaneous De-saturation After Long Periods in Saturation Phase
  • Compatible with Automatized Assembly Processes, Including Pb-free and Reflow Processes
  • Individual Marking for Compliance to Stringent Traceability Requirements
