ANS-BT105M Ultra-Small BLE 5.2 Bluetooth Module for Smart Sprayers

With the continuous upgrading of smart personal care devices, facial mist sprayers are transforming from traditional “manual devices” به “intelligent terminals.” By introducing Bluetooth Low Energy (BLE) communication technology, these sprayers can not only be remotely controlled via smartphone but also deeply integrated with apps to manage skincare data, personalize mode settings, and provide intelligent reminders, significantly enhancing user experience and product value. In this trend, ultra-small, low-power, and easily developed Bluetooth modules have become key components in smart facial mist sprayer solutions. The ANS-BT105M Bluetooth module, with its BLE 5.2 protocol, ultra-small 8.5×9.5mm size, 2μA deep sleep power consumption, and easy AT command development, demonstrates significant application advantages in smart facial mist sprayers.

I. Application Architecture of Intelligent Spray Hydration Device

The typical hardware architecture of an intelligent spray hydration device consists of the following core units:

Main Control MCU — Responsible for overall device scheduling, including atomization drive, LED indicators, and battery management.

Bluetooth Module (ANS-BT105M) — Connects to the MCU via UART serial port for bidirectional data communication.

Atomization Drive Unit — Piezoelectric ceramic/ultrasonic atomizing plate converts liquid into micron-sized atomized particles.

Battery and Charging Management Module — Lithium battery + charging IC, providing power to the device.

Mobile APP (iOS/Android)/Mini Program — User interface for remotely issuing control commands.

Communication Principle: The ANS-BT105M acts as a wireless bridge between the hydration device and the mobile phone, establishing a connection via the BLE 5.2 protocol. The mobile APP sends control commands (such as starting the spray or adjusting the duration). The module transmits the commands to the MCU via UART. After execution, the MCU feeds back status data, which is then transmitted back to the APP via the Bluetooth module, completing the bidirectional communication loop.

II. ANS-BT105M Core Parameters

Understanding the core technical parameters of the ANS-BT105M helps explain why it is a perfect fit for hydration device solutions:

Among the above parameters, three features are particularly crucial for hydration device solutions: Its ultra-compact 8.5×9.5mm size solves the problem of limited internal space in portable devices; 2μA deep sleep significantly extends the overall standby battery life; AT commands + serial port pass-through allow engineers without Bluetooth development experience to quickly complete integration.

III. Typical Application Scenarios

3.1 Remote Control of the Spray via Mobile Phone

After establishing a BLE connection between the user and the hydration device via a mobile app, the following can be achieved:

One-click on/off of the spray — Controlled by the mobile phone without touching the device.

Adjusting the spray duration — Customizable settings (30 seconds / 60 seconds / 90 seconds)

Intermittent spray mode — Suitable for long-term skincare routines, automatically intermittently spraying to avoid over-hydration.

3.2 Smart Reminder Function

Timed hydration reminder — Set a skincare schedule and receive timely reminders.

Water tank low water reminder — The MCU detects the water level sensor and synchronizes it to the app via Bluetooth.

Battery status synchronization — Real-time display of battery level, with low battery reminders.

3.3 Personalized Settings and Data Management

Usage frequency statistics — Automatically records daily usage frequency and duration.

Skincare habit recording — Intelligently recommends hydration solutions based on usage patterns.

User mode saving — Supports multiple presets for sensitive skin, dry skin, oily skin, etc., with one-click switching.

IV. ANS-BT105M Core Advantages

4.1 Ultra-small size, facilitating product miniaturization

The ANS-BT105M measures only 8.5 × 9.5 × 2.0 میلی متر, smaller than a fingernail:

It can be flexibly placed in small hydration devices such as lipstick-style, pen-style, and handheld portable models.

It provides greater design flexibility for water tank capacity, battery size, and overall appearance.

It reduces PCB footprint and simplifies board layout.

4.2 Ultra-low power consumption, significantly extending battery life

The ANS-BT105M Bluetooth module consumes only 2μA in deep sleep and supports serial port wake-up:

With the hydration device used 2-3 times daily and in deep sleep the rest of the time, the Bluetooth module’s standby power consumption is negligible.

The serial port wake-up mechanism ensures that the device responds immediately after the user opens the app, without waiting for a reconnection.

Practical effect: Taking a 500mAh lithium battery as an example, a 2μA standby current means only about 17mAh is consumed per year, which is almost negligible. The overall battery life depends on the frequency of atomization use; a single charge can support several weeks of daily use.

4.3 AT Commands + Serial Port Transparent Transmission: Simple and Efficient Development

No Bluetooth Protocol Development Required — MCU engineers do not need to master protocol stack knowledge such as GATT Service.

UART Serial Port Control Available — All Bluetooth operations are completed through simple serial port transmission and reception.

Accelerated Time-to-Market — Bluetooth integration time reduced from weeks to days.

4.4 BLE 5.2 Protocol: Stable and Reliable Connection

Optimized frequency hopping algorithm maintains stable connection even in congested 2.4GHz environments.

Maximum +6dBm transmit power, covering a typical operating distance of 1~5 meters.

3 Master/3 Slave Multi-Connection Capability, Supporting Multi-User or Device Interconnection.

V. Expanding Application Directions

Based on the BLE connectivity of the ANS-BT105M, the smart hydration device can be further expanded to include:

Smartwatch/Health App Integration — Intelligently recommending hydration solutions by combining ambient humidity and exercise data.

Ambient Humidity Sensor Integration — Automatically adjusting spray frequency based on humidity detection.

OTA Firmware Upgrade — Upgrade the hydration device firmware wirelessly via Bluetooth for continuous user experience optimization.

VI. Summary

The ANS-BT105M Ultra-small Bluetooth module solves the problem of limited internal space in hydration devices with its ultra-small 8.5×9.5mm size. Its extremely low power consumption (2μA deep sleep mode plus serial port wake-up) extends battery life, and its simplified development mode using AT commands and data pass-through shortens the product launch cycle. Combined with stable connectivity via the BLE 5.2 protocol, the ANS-BT105M provides greater flexibility and competitiveness for hydration device design, driving the comprehensive upgrade of traditional spray hydration devices from “single-function devices” به “intelligent personal care terminals.”
