GY-213v-HTU21D

Product introduction

The HTU21D(F) is a new digital humidity sensor with temperature output by MEAS. Setting new standards in

terms of size and intelligence, it is embedded in a reflow solderable Dual Flat No leads (DFN) package with a

small 3 x 3 x 0.9 mm footprint. This sensor provides calibrated, linearized signals in digital, I⊃2;C format.HTU21D(F) digital humidity sensors are dedicated humidity and temperature plug and play transducers for OEMapplications where reliable and accurate measurements are needed. Direct interface with a micro-controller ismade possible with the module for humidity and temperature digital outputs. These low power sensors aredesigned 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 electronicidentification code is stored on the chip – which can be read out by command. Low battery can be detected anda checksum improves communication reliability. The resolution of these digital humidity sensors can be changedby command (8/12bit up to 12/14bit for RH/T).With MEAS’ improvements and miniaturization of this sensor, the performance-to-price ratio has been improved– and eventually, any device should benefit from its cutting edge energy saving operation mode.Optional PTFE filter/membrane (F) protects HTU21D digital humidity sensors against dust and water immersion,as well as against contamination by particles. PTFE filter/membranes preserve a high response time. The whitePTFE filter/membrane is directly stuck on the sensor housing.

GY21-Si7021

Specifications:

The Si7021 I2C Humidity and Temperature Sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C Interface. The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of low-power, monolithic CMOS Sensor ICs with low drift and hysteresis, and excellent long term stability.The humidity and temperature sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory. This ensures that the sensors are fully interchangeable, with no recalibration or software changes required.The Si7021 is available in a 3x3 mm DFN package and is reflow solderable. It can be used as a hardware- and software-compatible drop-in upgrade for existing RH/temperature sensors in 3x3 mm DFN-6 packages, featuring precision sensing over a wider range and lower power consumption. The optional factory-installed cover offers a low profile, convenient means of protecting the sensor during assembly (e.g., reflow soldering) and throughout the life of the product, excluding liquids (hydrophobic/oleophobic) and particulates.The Si7021 offers an accurate, low-power, factory-calibrated digital solution ideal for measuring humidity, dew-point, and temperature, in applications ranging from HVAC/R and asset tracking to industrial and consumer platforms.
