That assumes the device needs to be running constantly collecting data.
What if a circuit passively charges a capacitor that once full powers up the device just long enough to take a reading and transmit it? This wouldn't be viable for things like air monitors where the sensors need to warm up for minutes, but it seems like it would be ideal for temperature sensors which can be influenced by the waste heat of the device.
