Selling: Temp, Hum Si7021



  • I have some self designed Circuit boards with NRF and Si7021.
    I do not use them anymore.
    Battery is CR123 used in Visonic alarm.
    When I replaced the battery on the IR sensor I continued to use it in these sensors.

    Contact me if you are interested so I can tel you more about it.
