How to connect Radionode UA sensor
UA53-H2S, hydrogen sulfide sensor Features
  • Basic sensor, high accuracy
    Basic sensor, high accuracy

    'Accuracy' is not an important factor to be considered when selecting a sensor. When purchasing products, the manufacturer's calibration sheet is enclosed, and if you use the UA Calibrator software, you can calibrate the value of the analog sensor used with the UA Series more precisely.

  • Trending IoT, digital data output
    Trending IoT, digital data output

    It is automatically recognized as a USB-SERIAL device in Windows, Mac, Android and Linux using USB CDC.
    Do you know the AT command used in the phone line modem? You can easily get sensor information with AT command only. Get information easily with AT commands instead of 4-20mA output.

  • Easy maintenance, calibration by pulling out like USB
    Easy maintenance, calibration by pulling out like USB

    In Korea, it is recommended to calibrate the sensor once a year to check the accuracy of the sensor. Since the UA Series is a USB type sensor, calibration and sensor replacement are very convenient. Ah! You can use it simply by plugging it into a USB port without any installation work, so cost savings can be realized now.

  • Remote monitoring, software provided
    Remote monitoring, software provided

    The advantage of UA products is that they enable real-time recording. We have prepared a variety of software to enable real-time recording with only UA devices. There are Tapaculo Lite (a program for PC) and Tapaculo Mobile (an Android app). After installing the software, connect the UA device to USB.

UA53-H2S, hydrogen sulfide sensor How to use
  • Various software development and IoT industrial environment construction

    Gas transmitter with USB output

    When a sensor is connected to a general transmitter, the measured value is output as a current, so it is very difficult to process it in software, and it is difficult to build an IoT environment in the industrial field. To solve this problem, we developed a gas sensor with USB output.

  • Fast reaction speed, long service life
