Amapanga mphamvu yotulutsa sopo ndi shampo ya zovala

STM-LPS33W-MEMS-pressure-sensor

Kutchedwa LPS33W, chipangizo chotchedwa IPx8 imatetezedwa ndi gel, ndipo imadzinenera kuti imayima: "madzi amchere, chlorini, bromine, zotupa monga sopo ndi shampoo, e-zamadzimadzi, ndi mankhwala ofunika monga n-pentane," anatero ST.

Chophimbacho ndi cylindrical (3.3mm diameter x 2.9mm), ndipo chimapangidwira, kuchepetsa kugwiritsira ntchito mphetezo pamene chophimba chosindikizidwa chikufunika, ndipo chivindikirocho chimakhala chosagwira ntchito.

Malinga ndi ndondomekoyi, gel ndi fomu yokhala ndi katundu, ndi katundu wake, pamodzi ndi zizindikiro zosungiramo zizindikiro monga asic, kukwaniritsa phokoso la phokoso la RMS la 0.008hPa.


"Kutha kuthamangitsidwa ndi kutsekemera kwapadera pamsonkhanowo kumakhala kochepa kwambiri, kumathamangira pang'ono kuposa ± 2hPa ndikupeza bwino molondola maola 72," anatero ST. "Mphoto ya kutentha imasunga molondola mkati mwa ± 3hPa pamwamba pa ntchitoyi kuyambira 0 ° C mpaka 65 ° C."

STM-LPS33W-MEMS-pressure-sensorKujambula kwa gelisi ndi pang'ono, chinsinsi, chomwe chimangokhala ndi mawonekedwe omwe amaperekedwa tsamba lazambiri (Table 9)

Zowonongeka zamakono zimasungidwa muzomwe sizingatheke, ndipo zimatulutsidwa mu zolembera poyendetsa ntchito yoyenera. Palibe chiwerengero chofunikira chofunika.

Kugwiritsa ntchito ndi 15μA mu 'high-performance', 3μA mu mode-low power mode ndi 1μA pamene kutseka.

FIFO ya 128-bit imasungira mpaka 40 peresenti ya 32bit pressure ndi deta kutentha, kuchepetsa kuchuluka kwa mgwirizano MCU mgwirizano, kulola wothandizira kugona mphamvu ndi kupulumutsa.

Kugulitsa ndi 1.7 mpaka 3.6V, ndipo ine2Mapulogalamu a digito a C ndi SPI amamangidwa, monga fyuluta yapansi.

Kukula kwa masamba kwayamba.
