ANS-BT105M：Ultra-small Bluetooth module with great intelligence

With the continuous upgrading of smart personal care devices, facial mist sprayers are transforming from traditional “manual devices” à “intelligent terminals.” By introducing Bluetooth communication technology, these sprayers can not only be remotely controlled but also interact with mobile apps, enhancing user experience and product value. In this trend, ultra-small, low-power, and easily developed Bluetooth modules have become key core components. Among them, the ANS-BT105M Bluetooth module demonstrates significant advantages in smart facial mist sprayers due to its excellent performance.

Application Architecture Description

The typical architecture of a smart facial mist sprayer is as follows:

• Main Control MCU (controls atomization, LED, and battery management)
• Bluetooth Module (ANS-BT105M)
• Atomization Drive Unit
• Battery and Charging Management Module
• Mobile App (iOS/Android)/Mini Program

The Bluetooth module connects to the main control unit via a UART serial port to achieve data communication and control command interaction.

Typical Application Scenarios

2.1 Remote Control of the Spray via Mobile Phone

After connecting the hydration device to a mobile app, users can:

• One-click turn the spray on/off
• Adjust the spray time (e.g., 30 seconds/60 seconds)
• Set an intermittent spray mode

2.2 Smart Reminder Function

Through Bluetooth connection, the following can be achieved:

• Timed hydration reminders (skincare management)
• Water tank low reminders
• Battery status synchronization

2.3 Personalized Settings and Data Recording

• Usage frequency statistics
• Skincare habit recording
• User mode saving (e.g., sensitive skin/dry skin)

Core Advantages of ANS-BT105M

3.1 Ultra-small size, facilitating product miniaturization design

The ANS-BT105M measures only 8.5 × 9.5 mm. mm, smaller than a fingernail:

• Easily integrated into a compact hydration device structure
• Provides greater freedom in appearance design (e.g., lipstick-style, portable)
• Reduces PCB space footprint, lowering overall device size

Especially suitable for: Portable, beauty, and small personal care devices

3.2 Ultra-low power consumption design, significantly extending battery life

The module supports deep sleep mode with only 2uA power consumption and serial port wake-up:

• Almost no power consumption in standby, greatly extending standby time
• Quick wake-up during use, no need for long connection waiting times
• Improves overall battery efficiency

Application value:

• Extends the hydration device’s lifespan (reduces charging frequency)
• Enhances user experience (use whenever needed)

3.3 AT commands + Data Transparency, Simple and Efficient Development

ANS-BT105M supports standard AT commands and serial port pass-through mode:

• No complex Bluetooth protocol development required
• MCU can control the device simply by sending commands via UART
• Quickly achieve communication between the APP and the device

Advantages:

• Shortened development cycle
• Lowered development threshold (no Bluetooth protocol stack experience required)
• Easy maintenance and upgrades

Expanding Application Directions

Based on ANS-BT105M, more intelligent functions can be added:

• Integration with smartwatches/health apps
• Ambient humidity detection and spray linkage
• AI skincare suggestions (cloud data analysis)

The ANS-BT105M Bluetooth module solves the problem of limited internal space in hydration devices with its ultra-small size of 8.5mm × 9.5mm. Its extremely low power consumption of 2μA deep sleep and serial port wake-up extends the device’s battery life. The simple development mode of AT commands and data transmission shortens the product launch cycle, providing greater flexibility and competitiveness for product design, upgrading the traditional spray hydration device from a “single-function device” to a “smart personal care terminal.”
