I am looking for a thermometer/sensor for a mobile application where I can track the temperature remotely via my mobile. WLAN/LAN is therefore not available and a Bluetooth or radio connection is not sufficient. Ideally, the sensor should send the data via mobile phone (possibly with a SIM card). Who knows something like this?
Good morning, ladies and gentlemen,
I'm an author with the publishing house heptades, and it's impossible to get my royalties. It's just very complicated to write and to find an audience... my question is, how can I find out if I have any sales, for example here with you?
