Description

The Holyiot-21061 BLE Sensor is a compact, fully integrated wireless sensing solution built around the Nordic Semiconductor nRF52832 system-on-chip. It leverages Bluetooth Low Energy 5.0 for efficient, long-range communication with smartphones and gateways, making it ideal for remote monitoring applications. The module’s architecture is optimized for minimal energy consumption, featuring deep sleep modes and intelligent sensor polling to maximize battery life from its standard CR2032 cell.

Encased in an IP67-rated waterproof housing, this sensor node is engineered for reliability in industrial, agricultural, and smart home environments. Its support for a comprehensive suite of MEMS and environmental sensors allows developers to implement complex condition monitoring, asset tracking, and motion detection systems without external components. The integrated design simplifies deployment, requiring only battery installation and app pairing to begin streaming real-time sensor data.

Key Features

  • Nordic Semiconductor nRF52832 SoC provides a powerful ARM Cortex-M4 core with integrated BLE 5.0 radio.
  • Comprehensive sensor suite includes 6-axis IMU (accelerometer/gyroscope), magnetometer, temperature, humidity, and barometric pressure.
  • IP67 waterproof and dustproof enclosure ensures reliable operation in harsh outdoor or industrial conditions.
  • Engineered for ultra-low power with configurable sleep modes, achieving an average current draw as low as 10µA.
  • Long-range BLE connectivity with +4 dBm transmit power for stable links up to 50 meters in open space.
  • Simple integration via standard 'BLE Sensor' mobile application for immediate data visualization and logging.
  • Compact form factor (30mm diameter, 8.4mm thick) enables discreet installation on assets, machinery, or within enclosures.

Applications

  • Wireless environmental monitoring for smart agriculture (temperature, humidity, barometric pressure).
  • Asset tracking and condition monitoring using motion (accelerometer/gyroscope) and orientation (magnetometer) data.
  • Industrial IoT (IIoT) for predictive maintenance on vibrating machinery or equipment.
  • Smart home automation for occupancy detection, window/door status, and indoor climate sensing.
  • Wearable and personal device development for fitness, health, and activity logging.

Frequently Asked Questions

How do I configure and read data from the Holyiot-21061 sensor?

Download the 'BLE Sensor' app on iOS or Android, enable Bluetooth, and scan for nearby devices. Select the Holyiot-21061 from the list to pair. Once connected, the app dashboard will display real-time readings from all enabled sensors, including acceleration, gyroscope, temperature, humidity, and barometric pressure. You can also log data and adjust basic sampling intervals directly within the application interface.

What is the expected battery life with a standard CR2032 battery?

Battery life depends heavily on sensor activation frequency and transmission intervals. With all sensors active and frequent BLE advertisements, expect several weeks. In optimized low-power mode, with sensors sampled infrequently and deep sleep between readings, the module's average current can drop to ~10µA, potentially achieving the advertised 900 days (approx. 2.5 years) of standby time on a fresh 220mAh CR2032 cell.

Can I develop custom firmware for the nRF52832 chip on this module?

Yes, the Nordic Semiconductor nRF52832 SoC is fully programmable using the nRF5 SDK, Zephyr RTOS, or Arduino Core for nRF52. You will need a SWD debugger (like a Segger or nRF52840 Dongle) to connect to the module's exposed programming pads. Develop your application to manage sensor I2C/SPI communication, implement power-saving sleep cycles, and control BLE advertising/connection parameters to tailor functionality for your specific IoT deployment.
