IST Flow Sens FS1 analog bridge circuit for cypress ble microcontroller

anthonythet

Hi,

I am Anthony working as an Embedded system engineer for an electronic design house.

Currently, I need to do hardware design for an application in which we use IST FS1 sensor for measuring air flow rate from cypress ble microcontroller.

I just googled about this sensor and I got some application bridge circuit for this sensor but they are for Arduino (for 5V range).

But what I need to interface is with ble microcontroller which can measure only 0 to 3.3V range.

Can I get application circuit for that sensor for cypress ble microcontroller?

I really need your help. Thanks.

  • Hello Anthony,

    If you are working for a design house is there not someone there who can help you a bit ?

    So far you haven't provided enough information to enable me (or anyone else) to help you much.

    The IST data sheets are limited but adequate, they have some additional material on their website.

    If you intend to measure the airflow you need to specify the range of flow rates you wish to cover, are you prepared to have adjustable resistors in your circuit for calibration or will you use maths and calibration data in the processor.

    Is there anything special about the processor, system power etc.

    If this is  a commercial application you should be able to get some help from IST.
