How does a Raspberry Pi WiFi extender work?
A Raspberry Pi WiFi Extender is a cheap and power efficient way of increasing the total range of your WiFi Network. A WiFi extender differs a fair bit from a WiFi access point. The main difference being that instead of getting its network connection from Ethernet, it instead gets its network connection from a WiFi adapter.
Can a Raspberry Pi be used as a motion sensor?
These Raspberry Pi sensors can be used to detect motion, but not all of them are “real” motion sensors. The PIR motion sensor has some advantages over other similar products: besides the low price, a signal is sent only if something moves. This allows you to wait for signal flanks using the GPIOs.
Why does my Raspberry Pi need a repeater?
You will face a fair bit of degradation in the speed of your network connection when connecting to the Wifi repeater. The main reason for this is that you must wait for the traffic to go over your initial Wi-Fi connection then be repeated from your Raspberry Pi for devices to connect to.
What kind of infrared sensor does Raspberry Pi use?
With the GP2Y0A02YK infrared distance meter, much more accurate measurements can be performed, as with e.g. the HC-SR04. The module is limited to a range of 20-150cm. Alternatively, the similar sensor GP2Y0A710K0F can be used, which has a range of 100 to 500cm.
What’s the difference between a WiFi extender and an access point?
A WiFi extender differs a fair bit from a WiFi access point. The main difference being that instead of getting its network connection from Ethernet, it instead gets its network connection from a WiFi adapter. For this reason, to complete this tutorial you will require two WiFi adapters, one of these must be access point capable.
Can a Raspberry Pi be used as a WiFi access point?
I’ve always been intrigued by the Raspberry Pi, especially the latest model, the Raspberry Pi 3 b, and as they can use an operating system I am familiar with (I use Raspbian, but it’s based on Linux Debian) I thought it wouldn’t be too difficult to set up and use as a wireless access point.
