Re: power up and on Sensors probably come in all shapes and sizes. Some embedded deep within other equipment. These look like instruments tethered to mini access points.

Re: power up and on Interesting observation. In some applications the number of sensors will be few and if any one of them fails will have to be replaced,

I had imagined that for some applications, however, the sensors would be so cheap that it would be cost-effective to deploy far more than you need and just let them fail one by one until the number of fails hits some critical threshold below which you can't sustain the application.

Next time I talk to someone involved with IoT, I'm going to ask that question.

Unless someone who knows the answer wants to chime in...?

power up and on Looks like their rechargeable batteries come with a 7v external solar panel. That must be getting fairly standard. Switching out components coud be a headache - especially in an IoT world with billions of sensors.
