  1. [SOLVED]Closed: Re: SHTW2 Sensor interface with nordic nrf52810 MCU

    Hi Klaus,

    It turns out my scope was aliasing the signal as the sample rate was too low. I set a quicker sample rate and got the required waveforms. Sample below:
    152920

    I analysed these...

    Re: which LINUX is best to learn embedded

    Hi,

    The first thing I would probably suggest to do is get yourself a Small computer like the others have suggested - Raspberry Pi, Beagle Bone etc which are based on Linux (if this what you...

    Hi Klaus,

    Sorry for the bad scope picture. I zoomed in and got the transitions, however the waveforms are noisy:

    From this I can make out a few things like the first data that I am...

    Hi Klaus,

    Please find the snapshot of the scope below:
    152887

    The part of the code that I use to read the sensor is below:


    Let me know if this is ok. Thanks
  5. [SOLVED]Closed: SHTW2 Sensor interface with nordic nrf52810 MCU

    Hi All,

    I am trying to interface the SHTW2 sensor from Sensirion with the nordic nrf52810 mcu. The Sensor uses I2C to communicate and nordic has its own version of I2C called TWI. From the...
  6. Closed: Re: Temperature/Acceleromete TA102 sensor: help needed to measure required sensor dat

    Hi Klaus,

    I checked the connections and they seem fine. I'll try with another capacitor just in case. But I think I'm supposed to get he 12 V DC voltage because it says so in the power...
  7. Closed: Re: Temperature/Acceleromete TA102 sensor: help needed to measure required sensor dat

    Hi Klaus,

    Oops. The indication in the second schematic is wrong. I connected it in the right way according to the first schematic. Thanks for pointing that out.

    If I use 15 Kohm then I get a...
  8. Closed: Re: Temperature/Acceleromete TA102 sensor: help needed to measure required sensor dat

    Hi Klaus,

    Let's start with what I have done so far:

    The sensor has an accelerometer and a temperature sensor and requires a constant current excitation to function. So we use the CRD for this...
  9. Closed: Re: Temperature/Acceleromete TA102 sensor: help needed to measure required sensor dat

    Hi Klaus,

    Thank you for the reply and sorry for the late response.

    Frankly, I don't yet have a complete circuit. I thought I could start first by just measuring the raw voltage values using an...
  10. Closed: Temperature/Acceleromete TA102 sensor: help needed to measure required sensor data

    Hi all,

    I am working on a project that involves using a 1-axis (if I'm not wrong) accelerometer for vibration sensing called TA102 by CTC. This sensor also gives a temperature reading. All this...
  11. Closed: Re: Understanding a current excitation circuit using Op Amps

    Hi FvM,

    Thank you for the quick reply. I had a look at the previous posts but I still have some missing pieces.

    I am trying to get a constant current source using the above schematic. To...
  12. Closed: Understanding a current excitation circuit using Op Amps

    Hi All,

    I am working on a project to sense the temperature using RTDs (Resistance Temperature detectors). I need some help in understanding the circuit attached. I am using this to excite a RTD...
