    I don't know the Pico's power specs, but maybe there's resistance
    on one of the electrical connections, such that the voltage drops
    more under load than where and when you measured it?

    The WiFi needs more....

    Yes. but allegedly not *that* much...On test it was the ultrasonic
    sensor that gave out before the wifi. At around 3.8V

    Hello

    This is a bit of a puzzle. My oil sensor stopped transmitting last
    night. I replaced the batteries just now and its working again. The voltage from is 3 x AA supply had dropped to 4.2V. This is supposed to
    be enough to work a PICO W off? And IIRC on test it worked down to
    around 3.8V or so.

    How did you check voltage? On working device, or on batteries itself?
    One of batteries may be depleted more than others and whole pack may give less current
    than usual.

    Best regards, Nikita.
