temperature sesing and wifi

[nikhil sasne]

hello there,

I m designing a system in that want to monitor temperature of room continuously so, in this case can raspberry pi product has such temperature sensors in build or i have to connect them externally.

Also, I want to transfer sensed temperature data through wi-fi. so, my question is, is it doable in Raspberry pi product?
if yes, then which product should i pickup?

Regard,
nikhil

The raspberry pi does have a built in temperature sensor but it will only tell you the temperature of the CPU which is way hotter than the surrounding environment.

The common solution is to use a DS18B20.

There are lots of tutorials out there but here is one

In terms of the WiFi element of your project.. what do you want to send it to?
I have mine setup through my home automation system so that I can browser to a webpage on my home network and see the temperature.

hello sir,

Thanks for reply.

Actually my requirement is that, if I have interfaced a temperature sensor with Raspberry pi, then in this case i want to send temperature value which is sensed by the temperature sensor to my computer using wi-fi.

so, meaning is that can wi-fi dongal connected to raspberry pi be used as transmitter for data sending ?

yes - if you have a Rpi3 then it has on-board wifi also bluetooth - both can connect to another device -
so you can connect to a wireless network via wi-fi
and direct to a device via bluetooth
