New Chip Brings Ultra-Low Power Wi-Fi Connectivity to IoT Devices
I'd love to know how they got the power consumption down so low! 28microwatts when active, that's really something.Some maths: 0.000025W.
A typical AA battery is 1.5V / 2Ah (https://www.powerstream.com/AA-tests.htm).
1.5*2 = 3Wh.
3Wh / 0.000025W = 120000 hours runtime.
= 5000 days = 13 years, off a single AA battery.That can't be right? That's incredible if true.
