With an accelerometer sensor integrated, the cloud can detect a falling accident through the 3-axis data and trigger the alarm. B1 wearable panic button is IP65 waterproof, it can be widely used in hotels, hospitals or schools for treatment compliance or emergency call.

• Chipset Nordic nRF52832
• Up to 140m advertising range
• Universal Type-C interface
• Rechargeable battery with 240mAh
• Multiple trigger types with different alarm task
• Wide temperature range between -20℃to 60℃



B1 Panic button will trigger an abnormal panic alarm mechanism when it stands still for more than a specified period. Users can set broadcast parameters according to actual use scenarios.

Reasons to Engage Your Bluetooth Gateway

Do you know what Bluetooth gateways are perfect for? They are ideal for Bluetooth-connected health applications, or any application that requires connectivity with Bluetooth. Bluetooth Gateway IoT facilitates remote access to a wide range of sensors and devices. This is done for proper monitoring and control purposes of health and wellness among others. Some of the most important key uses of the Bluetooth IoT gateway include health & wellness, sports & fitness, and smart homes & buildings.

In regard to health, the connected health applications, the gateway senses, reads, and monitor a variety of devices. This entails pule oximeters and glucose monitors as well as larger appliances such as home dialysis machines. On the other hand, the gateway way comes in handy when it comes to smart buildings. This is through remote control and monitoring of door locks and windows sills. The gateway also participates in the beacon locating application. In this article, features, benefits, parameters, and applications of Bluetooth Gateway will be discussed.
