You can fix it to the wall using screws or double sided tape. Have Command tidy and always at hand with this Simple Support.

The NRF24L01+ Module is an excellent wireless communication option between devices like the Arduino.

2.4 GHz 3dBi foldable antenna with reverse bias - SMA RF connector. Perfect for prototyping with RF ICs and Xbee modules. 50 ohm impedance. 10.16cm in length.

These wireless receivers work with our 434MHz transmitters. They can easily fit on a breadboard and work well with microcontrollers to create a very simple wireless data connection. Since these are just the receivers, they will only work one way data communication, you would need two pairs to act as a transmitter / receiver pair.

This is a fantastic find for SFE. A small, high-quality, quad-band, standard SMA terminated, cellular antenna.

You have no idea if thieves break into your house in your absence? Can you imagine if the light in your house turns on when you open the door? Or do you want your bedroom light to turn off automatically when you enter the living room? Any of your ideas will come true with the Sensor of Door/Window Wireless Sonoff DW2-Wi-Fi. The DW2-Wi-Fi comes in two pieces, the transmitter fits on the door or window and the magnetic key is fixed to the frame. It can help secure your door or window so you know your home is safe wherever you are. The sensor will trigger an alarm for your smartphone to warn you of an intruder when the door or window is opened.

The MINIR2, like the MINI's rugged Diy Two-Way Smart Switch, has been redesigned to bring safety and performance to an optimum level. The small and compact smart switch is used for different types of switch boxes, even the smallest standard EU switch box. Convenient to automate your appliances in the eWeLink app with your mobile phone or by voice command.

infrared devices are widely used and often for remotely controlled devices . With this IR receiver, your Arduino project is now able to receive commands from any IR remote controller.
