Body fat scale is a measuring device that can measure fat percentage, moisture, and bone mass in addition to body weight. The body fat scale adopts wireless communication, and the hardware resources of the body fat scale are limited. After the measurement is completed, the measurement result often needs to be transmitted to an external storage to prevent the loss of data coverage. Common wireless transmission methods for body fat scales, such as Bluetooth or Wi-Fi, and NFC (Near Field Communication) are also available abroad. The data receiving terminal is usually a smart device, such as a mobile phone or a pad. Install the corresponding program on the mobile phone or PAD, analyze the data format, extract the measurement results, and present them to the user.
Choose Blue Body Fat Scale or Wi-Fi Body Fat Scale in the market?
Bluetooth is a short-link broadcast technology, 100 meters to 100 meters in open areas, 10 meters commonly used indoors. The Bluetooth Technology Alliance officially launched the Bluetooth Core Specification 4.0 (called Bluetooth Smart) on June 30, 2010. It includes classic Bluetooth, high-speed Bluetooth and Bluetooth low energy protocols. Bluetooth low energy, it has a new protocol stack, can quickly establish simple links. The data transmission message is relatively short and the protocol is safe, and the protocol password encryption method is used for transmission.
Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN), usually using 2.4G UHF or 5G SHF ISM radio frequency bands. Connecting to a wireless LAN is usually password-protected; but it can also be open, which allows any device within the range of the WLAN to connect.
The applications of Wi-Fi and Bluetooth are complementary to some extent. Wi-Fi usually takes the access point as the center and forms an asymmetric client-server connection with the routing network through the access point. Bluetooth is usually a symmetrical connection between two Bluetooth devices. Bluetooth is suitable for simple applications where two devices are connected through the simplest configuration, such as the buttons of a headset and remote control, while Wi-Fi is more suitable for some complicated client settings and high-speed applications, especially like Access the network through the access node. However, Bluetooth access points do exist, and Wi-Fi point-to-point connections are not as easy as Bluetooth, but they are also possible. Wi-Fi Direct adds a point-to-point function similar to Bluetooth.
The bluetooth scale is suitable for personal use and can be used by users with mobile intelligent terminals, and has a wide range of universality. WIFI body fat scale, suitable for families and individuals. There are wireless routers in the home, or mobile phone AP hotspots. With the user’s permission, the measurement data directly arrives at the health data platform, and any user can obtain his own health data through the WeChat service account, mini program, or dedicated APP. Zhengtai Electrical Appliance designs special encryption and decryption algorithms to ensure data transmission security. WI-FI has higher power consumption than Bluetooth. Zhengtai Electrical Appliance uses polymer lithium batteries in these two body fat scales, which supports overtime and multiple use.
