1.) I want to build a circuit which should send pressure details to a mobile phone app. What are ways of communication with mobile?
2.) Should all the circuits which are to communicate with mobile phones should use rechargeable batteries or are there any long-lasting batteries that can be used for 3 years in one stretch.?
3.) What is the typical battery to be used for a typical bluetooth circuit?
