hi people,
made project , want share all. hope you.
in project raspberry pi has totally 16 input are 8 analog , 8 digital. each input show , transmit 1 data in 15 mins. database use google spreadsheets. these data shown on the website daily, weekly, monthly, annual , last data.
programmed raspberry pi on phyton. website is html, css , javascript.
digital input: 0-24v
analog input: 0-10v
can see overview of project on picture below. the materials;
the circuit of digital inputs: the circuit of analog inputs:
note :i attached other pictures on next post because of picture limit.
selamlar,
