arent both discontinued?

Aaymen ammari Hi everyone can someone tell me what is the difference between DHT11 and DHT22 ....

techielewOP•2/20/24, 4:46 AM

From DH22 page: "Compared to the DHT11, this sensor is more precise, more accurate, and works in a bigger range of temperature/humidity, but it's larger and more expensive."

https://www.adafruit.com/product/385

DHT22 temperature-humidity sensor + extras

The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on ...

Ttechielew arent both discontinued?

Umesh Lokhande•2/20/24, 4:59 AM

Yes. Still, both DHT11/DHT22 are widely popular and available across local retailers

Ttechielew Why the requirement for no ROS?

wafa_ath•2/20/24, 8:35 AM

Nao robot doesn't support ROS due to differences in communication protocols and software architecture

you there?

So Ive watched tht video youve sent

and you told me to download ibm watson cloud service as node red module

Urlostdad•2/20/24, 4:18 PM

but the thing is the imb watson is not free its aksing for money

Urlostdad•2/20/24, 4:19 PM

so do you know any other cloud plantforms we could use to access node red ui anywhere from the wrld

Umesh Lokhande•2/20/24, 4:22 PM

To create ui you don't need IBM Watson. I have just shown it as an example. You only have to install node-red-contrib-ui from Palette Manager. As shown in the video. To control RPi from other device can also be done locally as shown in the video. But you can pretty much use any other free cloud service

or just a free MQTT Server like
