Hi everyone, sorry if this sounds basic but I'm still very new to this so please bear with me!
So I'm making a product that will measure a baby's vitals and send that information to a robot and an app on the parent's phone.
Is there a way to send the data from the device on the baby to the robot and a phone app. I've already briefly looked into wifi and sending it over a text however, the device on the baby may not always be around stable internet (ie when they leave the house) and texting would require at least one continuing payment of a phone plan for unlimited texts. Is there a way I've missed, or a better way of doing this?
Once i know what components will be used, how do I measure how much power each component will use without using a tool (I won't initially be buy the parts, this is conceptual at the moment), Ideally the device measuring the baby's vitals will run for at least 8 hours continually
Thanks in advance for any of your help :D:D:D
