HTU21D(F) RH/T SENSOR IC Digital Relative Humidity sensor with Temperature output • DFN type package • Relative Humidity and Temperature Digital Output, I²C interface • Fully calibrated • Lead free sensor, reflow solderable • Low power consumption • Fast response time 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, I²C format. FEATURES • Full interchangeability with no calibration required in standard conditions • Instantaneous desaturation 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 APPLICATIONS • Home Appliance • Medical • Printers • Humidifier HTU21D(F) digital humidity sensors are dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed. Direct interface with a micro-controller is made possible with the module for humidity and temperature digital outputs. These low power sensors are 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 (8/12bit 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 white PTFE filter/membrane is directly stuck on the sensor housing. This membrane is allowing an IP67 compliant protection.

HTU21P(F) RH/T SENSOR IC Miniature Relative Humidity and Temperature SPECIFICATIONS       DFN type package Relative Humidity and Temperature Analog Output, PWM interface Fully calibrated Lead free sensor, reflow solderable Low power consumption Fast response time HTU21P(F) is a new humidity and temperature sensor by MEAS.Setting new standards in terms of size and intelligence, it is embedded in a reflow solderable Dual Flat No leads (DFN) package of 3 x 3 x 0.9 mm foot print. This sensor provides calibrated, linearized signals in analog pulse width modulated (PWM) format. FEATURES     Full interchangeability with no calibration required in standard conditions Instantaneous desaturation 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 APPLICATIONS      Automotive: defogging, HVAC Home Appliance Medical Printers Humidifier SENSOR SOLUTIONS /// HPC200_5 HTU21P(F) HTU21P(F) humidity sensors are dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed. These low power sensors are designed for high volume and cost sensitive applications with tight space constraints. PWM signal runs on a base frequency of 120Hz, the data signal is provided on SDA line. Pulling SCL high or low allows for switching between humidity and temperature, respectively. The sensor measures twice per second. The PWM signal may be converted to an analog ratiometric interface by adding a low pass filter. With MEAS’ improvements and miniaturization of the sensor, the performance-to-price ratio has been improved – and eventually, any device should benefit from the cutting edge energy saving operation mode. HTU21 is also available with digital I²C (HTU21D(F)). Optional PTFE filter/membrane (F) protects HTU21P analog humidity 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 compliance protection. 05/2017 Page 1 PDF
