[57north-discuss] Missing component

[Tanev, Ventsislav]

Dear hackers,


I am a fourth year student at the University of Aberdeen doing Computing Science. I am working on a project regarding message payload and its relation to battery usage. I was going to simulate this with Arduino/Raspberry pi. The idea is to get sensor data and
    1) form a character string with all the necessary information and pass it via Wifi(ESP8266) - this will result in lighter message, but it would require some parsing on the other side

    2) construct and object and send it via Wifi - this will result in a heavier message, but it wont require parsing

I was originally hoping to measure the current consumption with a multimeter, but the current consumption might fluctuate too quick for me to register meaningful data. What I believe will work is to measure how much power will be consumed with a current sensor (ACS712) and log the data. However as I don't have such sensor and the estimated delivery for one is way past my deadline I was hoping that you guys have 1 I could borrow.


In all cases any feedback would be greatly appreciated [😊]


Kind regards,

Ventsislav
