Wireless network adapter and other components
-
Hello everyone,
I was wondering if someone could provide me with links to a wireless network adapter most suitable for the RPI 3 B model. I was also searching for a mic and audio component most suitable and couldn’t find anything. I was also thinking of implementing a sensor and can’t decide between PIR and IR , that’s why I would like to hear your opinions on the matter.
Thanks to anyone that replies. -
Why not use the onboard WiFi adapter on the Raspberry Pi3 B ?
On the sensor topic . Why not go with a Microwave Sensor. Search posts by @fozzie as he has just installed one and likes it alot!
I searched for the thread for you and here it is https://forum.magicmirror.builders/topic/11704/update-replaced-my-pir-sensor-with-a-doppler-microwave-sensor/12
