Kestrel DROP D3 Bluetooth Data Logger - Temperature | Humidity | Pressure
About the Kestrel DROP D3 Bluetooth Data Logger - Temperature | Humidity | Pressure
Product Overview
The Kestrel DROP D3 Bluetooth Data Logger is a professional-grade environmental monitoring solution that measures and logs temperature, relative humidity, and barometric pressure. Perfect for weather monitoring, environmental research, HVAC applications, storage facilities, and any situation where comprehensive atmospheric data is essential.
Frequently Asked Questions
What does the Kestrel DROP D3 measure?
The DROP D3 measures three critical environmental parameters: temperature, relative humidity, and barometric pressure. This combination provides complete atmospheric monitoring for weather tracking, climate studies, and environmental control applications.
How do I connect the DROP D3 to my device?
Download the free Kestrel LiNK app (available for iOS and Android), enable Bluetooth on your device, and follow the in-app pairing instructions. The DROP D3 will automatically connect when in range (up to 100 feet).
What's the difference between the D2 and D3 models?
The D2 measures temperature and humidity only. The D3 adds barometric pressure measurement, making it ideal for weather monitoring, altitude tracking, and applications where atmospheric pressure data is important. If you need complete weather data, choose the D3.
Is the DROP D3 waterproof?
Yes! The DROP D3 is fully waterproof (IP67 rated) and even floats, making it perfect for outdoor weather stations, marine environments, agricultural monitoring, and any location where moisture or rain is present.
What is the measurement range and accuracy?
Temperature: -22°F to 140°F (-30°C to 60°C), ±0.9°F (±0.5°C)
Relative Humidity: 0% to 100% RH, ±2% RH
Barometric Pressure: 700 to 1100 hPa (mbar), ±1.5 hPa
All sensors are factory calibrated to NIST-traceable standards.
How long does the battery last?
The DROP D3 runs on a standard CR2032 coin cell battery that typically lasts 2+ years with normal use. Battery life depends on logging interval and Bluetooth connection frequency. The battery is user-replaceable.
How much data can it store?
The DROP D3 can store over 2,000 data points internally. When connected to the Kestrel LiNK app, data is automatically uploaded to the cloud for unlimited storage and long-term analysis.
Can I set custom logging intervals?
Yes, you can customize logging intervals from 2 seconds to 12 hours using the Kestrel LiNK app. This allows you to balance data resolution with battery life and storage capacity based on your specific monitoring needs.
Does it work without a smartphone nearby?
Absolutely! The DROP D3 logs data independently and stores it internally. You only need your smartphone to configure settings, view real-time data, or download logged information. Perfect for remote monitoring locations.
Can I set alerts and notifications?
Yes, the Kestrel LiNK app allows you to set custom high/low threshold alerts for temperature, humidity, and pressure. You'll receive push notifications when conditions exceed your specified limits—ideal for monitoring storage conditions, greenhouses, or weather changes.
What applications is the D3 best suited for?
The D3 is perfect for weather monitoring, HVAC system verification, storage facility monitoring, greenhouse climate control, wine cellar management, museum and archive preservation, agricultural monitoring, and any application requiring complete atmospheric data.
Can I use multiple DROP units together?
Yes, you can monitor multiple DROP data loggers simultaneously through the Kestrel LiNK app. This is perfect for comparing conditions across different rooms, monitoring multiple storage areas, or tracking microclimates in different locations.
What's included in the box?
Each DROP D3 includes the data logger unit, CR2032 battery (pre-installed), quick start guide, and access to the free Kestrel LiNK app with cloud storage.
Is there a subscription fee for the app or cloud storage?
No! The Kestrel LiNK app and cloud data storage are completely free with no subscription fees or hidden costs. All features are included at no additional charge.
Can I export my data?
Yes, the Kestrel LiNK app allows you to export data in CSV format for analysis in Excel, Google Sheets, or other data analysis software. Perfect for creating reports, tracking trends, or compliance documentation.
How does barometric pressure help with weather monitoring?
Barometric pressure is a key indicator of weather changes. Rising pressure typically indicates improving weather, while falling pressure often signals approaching storms or precipitation. The D3's pressure readings help you track and predict local weather patterns.
Can the D3 be used outdoors year-round?
Yes! The D3's waterproof construction and wide operating temperature range (-22°F to 140°F) make it suitable for year-round outdoor deployment in virtually any climate. It's built to withstand rain, snow, humidity, and temperature extremes.
How accurate is the pressure sensor for altitude changes?
The D3's barometric pressure sensor (±1.5 hPa accuracy) can detect altitude changes of approximately 40-50 feet. This makes it useful for tracking elevation changes during hiking, monitoring pressure trends, or verifying HVAC system pressurization.
Can I mount the D3 in a specific location?
Yes! The compact, lightweight design makes it easy to place the D3 anywhere you need monitoring. You can set it on a shelf, mount it with adhesive, hang it, or place it in a weather station enclosure for permanent outdoor installation.
Is the D3 suitable for professional or commercial use?
Absolutely! The DROP D3 meets professional standards and is used by meteorologists, HVAC technicians, facility managers, researchers, and commercial operations that require accurate, reliable environmental monitoring with documented data logging.
