How Can Bluetooth Integration Improve Smart Pulse Oximeters for Wireless Health Monitoring?

1. Application Background

Pulse oximeters are primarily used to measure blood oxygen saturation (SpO₂) and pulse rate. They are widely applied in home health care, exercise monitoring, and hospital care settings. Traditional pulse oximeters have limited data transmission capabilities, but by integrating Bluetooth modules, wireless data transmission can be enabled, enhancing user experience and remote monitoring capabilities.

2. Solution Overview

By integrating Bluetooth modules (such as BLE or a Bluetooth master-slave all-in-one module) into the pulse oximeter, it becomes capable of wirelessly connecting to smart devices (smartphones, tablets, smartwatches) or medical monitoring systems, enabling real-time data synchronization, remote management, and intelligent health analysis.

3. Solution Architecture

• Pulse oximeter (with built-in Bluetooth module)
• Smartphone app / Smart wearable devices / Medical gateway
• Cloud-based health management platform (optional)

Bluetooth Module Selection:

1. BLE (Bluetooth Low Energy) – Suitable for home and personal health monitoring, with low data transmission power consumption, and compatible with smartphone apps.
2. Master-Slave All-in-One Bluetooth (e.g., RHA-BT101M) – Suitable for connecting multiple devices simultaneously, such as a smartphone + smartwatch + hospital monitoring system. a. When the RHA-BT101M connects to a smartphone or other Bluetooth devices, it functions as a slave device. b. When RHA-BT101M connects to other Bluetooth devices, it functions as the master. To set up as the master, how should it be configured to connect to other devices?

Master-Slave Single Connection Transparent Transmission Mode:

1. Register UUID:

   AT+UUID{=param1,param2,param3}

   (if using our module as a slave, skip this step)
2. Connection address:

   AT+CONN=param1param2

   (pay attention to the address type)
3. Transparent transmission of data

4. Solution Advantages

• Wireless transmission: Replaces traditional wired methods, enhancing convenience and mobility.
• Low-power operation: Ideal for long-term monitoring devices, extending battery life.
• Real-time data synchronization: Syncs pulse oximeter data to apps for health trend analysis.
• Remote monitoring: Through cloud platforms, doctors or family members can remotely view data, improving health management.
• Smart alerts: In case of abnormal oxygen levels, the app can send notifications or alarms, enhancing safety.

5. Typical Application Scenarios

• Home health monitoring: Users can view blood oxygen data on their smartphones to stay informed about their health.
• Exercise monitoring: The pulse oximeter can connect to a smartwatch to monitor blood oxygen levels during exercise.
• Hospital remote care: Data can be synced to medical platforms for doctors to remotely monitor and diagnose.
• Sleep monitoring: Nighttime monitoring of blood oxygen levels to assess sleep quality and prevent sleep apnea syndrome.

By integrating the RHA-BT101M Bluetooth module into the pulse oximeter, it enables wireless data transmission, intelligent monitoring, and remote management, enhancing the user experience and providing an efficient solution for home healthcare and remote health management.
