External Sensors

[arfhamza]

Hello!

I know that there's a temperature sensors built in the nrf52840 device.
what i would like to do is to connect an external temp sensors, and get the data from it in order to compare it with the built in temp sensor.

I'm still new to this, and i need some help with this.
could someone help me ?

thank you in advance

Besides that you're using an NRF52840, you have provided absolutely no information regarding your issue. I doubt anyone will be able to help you like that.

Figure out first what you want and then post questions about that - I need help to get data from a temperature sensor is too broad.

Hello 

What i wanted to say is that i want to connect an external temp sensor tp the nrf52840 device using GPIO, and i want to get temp data from it. I'm asking if there is some king of tutorial on how to connect sensors and get data using GPIO

Thank you

[Andy]

What do you mean with GPIO? Is it an analog or digital sensor?

You can see the available peripheral examples here.

Its the DHT22 sensor

I don't know every sensor in the world, what kind of sensor is it? 

[arfhamza]

 sorry for not mention it, DHT22 is a digital  sensor

[Andy]

Then I guess it's an I2C sensor. I'd recommend taking a look at the TWI manager example and the TWI sensor example.
