Hi This is Riaz. I am using this forum for the first time and apologies in advance if i made any mistake.
so here is what i need , i need to monitor the temperature of 8 different refrigerators in a cell phone and i want to send some kind of alarm to the cell phone if the temperature goes below or above the certain range. i need to know few things. 1- can i do it using arduino if yes what version should i use.? (i am thing about MKR1010).?? 2-for 8 different locations ,will i need to use 8 arduino boards..?? 3- is it possible to use single app(Blynk) to monitor the temperature from 8 arduino boars??
any suggestion or help is appreciated.
