Is the calibrated / compenstated pressure output supposed to correct for ambient temperature changing?
the scaled raw temp value is featured in the equation for the comp pressure but if i heat the sensor without changing the pressure, the comp pressure reading drops (not expected) and the calibrated (degrees C ) temperature climbs (as expected)
i have 2 different sensors that behave the same, i can see the calibration coeffs are different but in the same ranges for each parameter so I am pretty sure I am doing all the right stuff with the numbers as the calibrated outputs are 'correct' in as much as they output believable numbers but with heat alone as a modulation to the sensor, the pressure is moving
am i missing something here?
i am hoping to use the 2 in a differential mode which seems ok so far as long as the temperatue doesn't change
thanks

Show LessHello,
in our design we are using the obsolete CY7B992-7JI. Is a replacement available?
Hi,
Their products(https://www.bosch-sensortec.com/news/accurate-indoor-localization-can-save-thousands-of-lives-enabled-by-pressures-sensing-solution.html) seem to claim to be FCC(https://www.federalregister.gov/documents/2020/01/16/2019-28483/wireless-e911-location-accuracy-requirements) compliant, but what about the DP310?
Since the absolute accuracy of the DP310 is 1pHa (±8m), is it not possible to comply with the FCC standard ±3?
Smartphone vendors seem to want to build pressure sensors into smartphones to enhance GPS capabilities in order to comply with the FCC.
Best regards,

Hi,
I tried using the ISO15693 command 0x20 to read the block, but it was unsuccessful. I saw the other post it supposed to support the command set. I know this chip has both secured memory and plain memory area, how do I address the plain memory area? Do I need the sector select command?
Thanks.
Show Less我們使用了 CY51x7 IC,我們嘗試將低頻晶振設置為 LFF 模式。
我們要使用 50MHz 的晶振,我們按照 LFF 晶振的振盪器相關參數設置。
我們設置振盪器相關參數和 XT-Pattern。但
我們發現如果我們使用 XO_DOUBLER_ENB =1(禁用),我們可以獲得 50MHz 輸出,但如果我們使用 XO_DOUBLER_ENB=0(啟用),我們無法獲得 100MHz 頻率輸出。x
我們如何獲得正確的參數?我們在編程規範中找不到更詳細的寄存器信息,如 XO_CAP 和 XO_AMPLICE。如何獲得更詳細的信息?

Please provide SGS report of ESD251-B1-W0201
I have laser sensor. I want to detect pulse signals below 10ns with MCU. What criteria are important for the MCU to detect this signal? e.g Instruction cycle speed, Clock speed or GPIO speed... Which one? or what is important?
Many thanks in advance.

Dear Sir,
DPS368 as datasheet discription, it can detect the temperature, right? thanks.
The DPS368 is a miniaturized Digital
Barometric Air Pressure Sensor robust
against water, dust and humidity. It offers a
high accuracy and a low current
consumption, capable of measuring both
pressure and temperature. The pressure
sensor element is based on a capacitive
sensing principle which guarantees high
precision during temperature changes
Bitte um Ihre RoHS Konformitätserklärung zu Cypress_WSON-8L_5x6mm, Markingcode FL064LAF01
Danke im Voraus
