Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →It is a special type of antenna that is used in devices that are operated through the wifi signals. It is very powerful and small in size, which can help different devices connect at 2.4 GHz. it is used the the modems. Wifi routers, smart appliances, IOT devices, and many other products that work on the wireless network.
This antenna is made in such a way that it can work at 2.4 GHz frequency and is used in Wi-Fi networks. It is very effective and is stable, and provides a consistent connection with the devices.
The strength of the antenna to pick up the signals is 2.5 dBi. By covering a wider region to cover the signals, it strikes a compromise between range and coverage.
It means it can capture the signals in all directions, and it becomes easy to capture the signals from different devices like the IOT devices, phone, laptop, and more.
It is small in size and is very effective, and is known as an RF connector.
It is excellent for the connections and flexible. The connection between the ports and connections is its responsibility.
These can be used in routers, Wi-Fi devices, drones, smart house appliances, cameras, wireless devices, Raspberry and many more.
It is very effective in improving the signal strength, it is lightweight, very versatile, does not cost too much, and has a wide coverage of the signal.
This antenna might be the one you are looking for if you happen to look for an antenna that connects to different kinds of IPEX (u.FL) connectors.
It is a vertically polarized antenna that supports frequency bands of 2400mHz to 2500mHz. It has a signal gain of 2.5dBi, with an impedance of 50Ω and uses up to 50W power. It could operate in temperatures ranging from -40°C to 70°C, and needs to be stored in places with -55°C to 80°C ambient temperature. This antenna has U.FL to SMA cable that enables you to use it with U.FL, as well as SMA components, and is compliant to the Federal Communication Commission(FCC) Part 15 compliance.
It has lightning protection with a direct ground connection.
The dimensions of the antenna are as follows:
- Antenna Dimension: 110mm straight/ 92mm + 18mm bent
- Tail Line Cable Length: 200mm
- Package Size: 295mm x 110mm x 60mm
- Weight: 90 grams
This antenna is suitable for indoor use.
