I am VERY new to electronics (finance background … so all foreign to me), but have a problem I need help with.
I need 20 different items that need to be measured and data sent wirelessly to remote laptop.
One company I spoke to offered me a $3500 “sensor” per unit to do the job, so the conversation ended very quickly.
I bought (w/end just past) an arduino board, an ultrasonic sensor and breadboard and now (for <$40) have it measuring onto my laptop.
Next issue is to get 20 of them (as proto-type) to locate in field and communicate wirelessly to laptop. If successful, the qty will go to 1000 immediatley. I would like to avoid a sim card in each.
can someone please assist me to take step #2
(appologies for length of above … my first ever “blog”)
