The +\/-2% RH humidity accuracy and +\/-0.2C temperature accuracy exceed the requirements for HVAC, weather stations, and industrial monitoring. The 550 nA current consumption at 1 Hz measurement rate makes it suitable for battery-powered wearables and IoT sensors that can run for years on a coin cell. The 14-bit resolution for both humidity and temperature provides fine-grained measurements. The I2C interface supports up to 400 kHz for fast data readout. The WLCSP package is the smallest available for a humidity sensor, enabling integration into space-constrained designs like smartwatches and earbuds.","working_principle":"The HDC2010YPA uses a capacitive sensing element for humidity and a bandgap temperature sensor. The humidity sensor consists of a polymer dielectric between two electrodes. Water vapor absorption changes the polymer's dielectric constant, altering the capacitance. A precision capacitance-to-digital converter measures this change with 14-bit resolution. The temperature sensor uses a bandgap reference circuit that generates a PTAT (Proportional To Absolute Temperature) voltage, digitized by the same ADC. Both measurements are performed sequentially in a single conversion cycle. The 550 nA low current is achieved by duty-cycling: the sensor wakes from sleep, performs a measurement (which takes approximately 6 ms at 14-bit resolution), and returns to sleep until the next measurement cycle. The auto-measurement mode allows the device to perform periodic measurements independently, storing results in data registers and optionally asserting an interrupt when data is ready or when readings exceed programmable thresholds.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>A1<\/td><td>SCL<\/td><td>Input<\/td><td>I2C clock<\/td><\/tr><tr><td>A2<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr><tr><td>B1<\/td><td>SDA<\/td><td>I\/O<\/td><td>I2C data<\/td><\/tr><tr><td>B2<\/td><td>VDD<\/td><td>Power<\/td><td>Supply voltage (1.62-3.6V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Smartwatch with 550nA humidity monitoring for dew point calculation<\/li><li>HVAC duct humidity sensor with +\/-2%RH accuracy for efficiency control<\/li><li>Smart home weather station with 14-bit temperature and humidity data<\/li><li>Refrigerator defrost control with +\/-0.2C temperature accuracy<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>HDC2080DMBR<\/td><td>DMB-6<\/td><td>Similar, larger package<\/td><\/tr><tr><td>Sensirion<\/td><td>SHT30-DIS-B<\/td><td>DFN-8<\/td><td>+\/-2%RH, +\/-0.3C<\/td><\/tr><tr><td>Bosch<\/td><td>BME280<\/td><td>LGA-8<\/td><td>Humidity+temp+pressure, 3-in-1<\/td><\/tr><tr><td>Silicon Labs<\/td><td>SI7021-A20<\/td><td>DFN-6<\/td><td>+\/-3%RH, similar class<\/td><\/tr><tr><td>TE Connectivity<\/td><td>HTU21D<\/td><td>DFN-6<\/td><td>+\/-2%RH, alternative<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/6912","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=6912"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/6912\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=6912"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=6912"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=6912"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=6912"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
