Re: Mean of 60 temperature sensors

1-wire like DS18B20 should be good for this work. And dont forget to calibrate the sensor.

Pyrebase will send data from Raspberry into Firebase (database), and then add simple javascript from Firebase into HTML file, you will get result. or maybe you can use Tornado web server, it use Web so...

Hai,

i'm looking for DS18B20 calibration result, maybe you have it. The reason why i ask, because i dont have termometer with high accuracy to calibrate the sensor. I just want to calibrate my sensor from 18 celsius - 30 celsius.
