HTU20D(F) RH/T SENSOR IC Digital Relative Humidity sensor with Temperature output DFN type package Relative Humidity and Temperature Digital Output, IC interface Fully calibrated Lead free sensor, reflow solderable Low power consumption Fast response time HTU20D(F), is a new digital humidity sensor with temperature output of 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 foot print. This sensor provides calibrated, linearized signals in digital, IC format. FEATURES HTU20D(F) digital humidity sensors are dedicated humidity and temperature plug and play transducers for OEM applications where Full interchangeability with no calibration reliable and accurate measurements are needed. Direct interface with required in standard conditions a micro-controller is made possible with the module for humidity and Instantaneous desaturation after long periods in temperature digital outputs. These low power sensors are designed for saturation phase high volume and cost sensitive applications with tight space Compatible with automatized assembly constraints. processes, including Pb free and reflow Every sensor is individually calibrated and tested. Lot identification is processes printed on the sensor and an electronic identification code is stored on Individual marking for compliance to stringent the chip which can be read out by command. Low battery can be traceability requirements detected and a checksum improves communication reliability. The resolution of these digital humidity sensor can be changed by APPLICATIONS command (8/12bit up to 12/14bit for RH/T). Home Appliance With MEAS improvements and miniaturization of this sensor, the performance-to-price ratio has been improved and eventually, any Medical device should benefit from the cutting-edge energy saving operation Printers mode. Humidifier Optional PTFE filter/membrane (F) protects HTU20D digital humidity Multimedia: Smartphone, Tablet, sensors against dust and water immersion, as well as against contamination by particles. PTFE filter/membrane preserves a high response time. The white PTFE filter/membrane is directly stuck on the sensor housing. This membrane is allowing an IP67 compliant protection.
