Description

The Holyiot Logger L1 is a professional-grade, wireless environmental data logger built for industrial and commercial monitoring applications. It integrates high-precision sensors for temperature, humidity, barometric pressure, and acceleration into a single, ultra-compact unit. Communication is handled via Bluetooth Low Energy 5.1, providing a reliable and energy-efficient link to a smartphone or gateway for data visualization and management without the need for complex wiring.

Engineered for durability, the logger functions across a wide -40°C to +60°C temperature range, making it suitable for cold chain logistics, HVAC system verification, warehouse monitoring, and outdoor environmental studies. Its integrated 3M adhesive allows for quick deployment on virtually any surface. The device is optimized for ultra-low power consumption, leveraging the BLE protocol and efficient power management to maximize the operational life of its user-replaceable CR2450 battery during long-term logging campaigns.

Key Features

  • Quad-Sensor Data Logger capturing temperature, relative humidity, barometric pressure, and 3-axis acceleration.
  • High-Precision Measurement with industry-standard accuracy for reliable environmental compliance and process monitoring.
  • Bluetooth 5.1 Low Energy (BLE) ensures extended range and stable connectivity with modern smartphones and IoT hubs.
  • Extended Operational Range from -40°C to +60°C and 0-100% RH for deployment in challenging industrial and outdoor settings.
  • Compact & Mountable Design (35x35mm) with a 3M adhesive backing for discrete, flexible installation on equipment, walls, or assets.
  • Long-Duration Logging supported by large onboard memory and optimized power draw from the CR2450 battery.
  • User-Friendly Mobile App provides real-time graphs, data history, alert configuration, and simple export to CSV format.

Applications

  • Cold Chain & Pharmaceutical Logistics Monitoring for temperature and humidity-sensitive goods.
  • HVAC System Performance Validation and indoor environmental quality (IEQ) tracking in buildings.
  • Industrial Process & Warehouse Monitoring for compliance with storage condition standards.
  • Agricultural & Greenhouse Environmental Sensing for crop growth optimization.
  • Asset Tracking & Condition Monitoring by leveraging accelerometer data for shock/vibration detection.

Frequently Asked Questions

How do I connect the Holyiot Logger L1 to my smartphone and start logging data?

Download the official Holyiot app from your phone's app store. Enable Bluetooth on your phone, power on the logger, and open the app. The device should appear in the scanner list—select it to pair. Once connected, you can configure logging intervals, view real-time sensor readings on the dashboard, and access the history tab to review or export stored data as a CSV file for analysis.

What is the expected battery life of the Holyiot L1 logger using the CR2450 cell?

Battery life depends heavily on the configured sampling interval and Bluetooth connection frequency. With a moderate logging interval (e.g., every 10 minutes) and minimal app connections, a standard CR2450 battery can typically last several months. For maximum longevity, minimize the frequency of active Bluetooth data streaming and use the lowest practical sampling rate that meets your data resolution requirements.

Can the Holyiot L1 operate and log data in environments below freezing?

Yes, the Holyiot L1 is specifically rated for operation from -40°C to +60°C, making it suitable for freezer monitoring, cold storage, and outdoor winter conditions. The sensors and electronics are designed to maintain specified accuracy across this full range. Note that battery performance may decrease at very low temperatures, which should be factored into battery replacement schedules for critical applications.

How do I access the historical data stored on the logger's internal memory?

Historical data is accessed via the companion mobile app. Ensure your phone's Bluetooth is on and open the app while near the logger. After connecting to the device, navigate to the 'History' or 'Data' section within the app. Here, you can scroll through timestamped records and typically find an 'Export' or 'Share' button to send the full dataset as a CSV file via email or cloud storage for further analysis in spreadsheet software.
