Heat stress in livestock can lead to serious animal health issues, decreased milk production, and compromised herd performance.
Stay informed of heat conditions in the barn or during transport with the Kestrel D2 Livestock Heat Stress Monitor. Multiple built-in environmental measurements mean your DROP D2 can also be used for many other agricultural applications including hay and feed storage areas and greenhouses.
The Kestrel Drop D2 Livestock Heat Stress Monitor is a very affordable rugged heat stress monitor that can be used in the barn, during transport, or anywhere livestock are housed. Simply hang in place wherever insight into conditions is needed, and access current conditions and historical readings with your iOS or Android device. Designed by Kestrel with input from some of the world's most respected experts in livestock heat stress, the Kestrel DROP D2 Livestock Heat Stress Monitor is designed to help you MEASURE and MANAGE your animals’ heat stress, ensuring you MAXIMIZE your bottom line.
- Direct readout of Temperature Humidity Index (THI) – a dairy cattle specific measurement that provides guidance for when heat stress will start to reduce milk production.
- Also measures heat stress index, temperature, humidity and dew point for application to many types of livestock and agricultural applications.
- The EASIEST and most accurate way to monitor and track environmental measurements critical to agriculture in almost any farm, home or transport location – wet or dry, indoors or out.
- Easily hangs inside a barn, transport vehicle or wherever livestock are housed.
- Horse shippers - monitor trailer temperatures and heat index from inside your truck! Know when to find shade or take a break to water your horses.
- View data wirelessly with Kestrel LiNK app, powered by Bluetooth® low energy, on mobile devices and computers when within 100’ of device. See, save and share data from multiple DROPs with just one phone or tablet.
- Store thousands of data points and get months of logging on a single coin-cell battery - customize logging rate, connections and alerts
- Android 4.3 and higher. Works with most Android devices with Bluetooth® low energy, including Samsung Galaxy, Nexus 4, Motorola, Android and other recent generation phones and tablets.
- iOS 6 installed iPhone 4s, iPad 3rd generation or later.

Kestrel D1 - D3 Sensor Specifications
SENSORS
| SENSORS | ACCURACY (+/-) | RESOLUTION | SPECIFICATION RANGE | NOTES |
|---|---|---|---|---|
| AmbientTemperature | 0.9 °F 0.5 °C |
0.1 °F 0.1 °C | 14 to 131°F -10 to 55 °C |
Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. For greatest accuracy, avoid direct sunlight on the temperature sensor and prolonged sunlight exposure to the unit in low airflow conditions. Calibration drift is negligible for the life of the product. For further details, see Battery Operational Temperature Limits. |
| Relative Humidity | 2%RH | 0.1 %RH | 10 to 90% 25°C noncondensing | To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift is typically less than ±0.25% per year. |
| Pressure | 1.5 hPa|mbar 0.044 inHg 0.022 PSI |
0.1 hPa|mbar 0.01 inHg 0.01 PSI |
25°C/77°F 700-1100 hPa|mbar 20.67-32.48 inHg 10.15-15.95 PSI |
Monolithic silicon piezo-resistive pressure sensor with second-order temperature correction. Between 1100–1600 mbar, unit will operate with reduced accuracy. Sensor may not operate above 1600 mbar and can be damaged above 6,000 mbar or below 10 mbar. Calibration drift is negligible for the life of the product. |

| Response Time & Display Update | Display updates every 1 second. After exposure to large environmental changes, all sensors require an equilibration period to reach stated accuracy. Measurements employing RH may require longer periods particularly after prolonged exposure to very high or very low humidity. WBGT requires about 8 minutes to reach 95% accuracy and about 15 minutes to reach 99% accuracy after exposure to large environmental changes. |
| Data Storage | Logged history stored for every measured value. Auto-store interval settable from 2 seconds to 12 hours*, overwrite on or off. D1: >13,000 data points, D2: >7,000 data points, D3: >6,000 data points. |
| Bluetooth® Data Connect Option | Wireless range up to 100ft|30m. Compatible with Kestrel LiNK app for iOS (model 4s and later) and select Android products (Android 4.3 and higher) (See website for complete list of compatible 3rd party apps). |
| Certifications | CE certified, RoHS, FCC, IC tested and WEEE compliant. Individually tested to NIST-traceable standards. |
| Origin | Designed and manufactured in the USA from US and imported components. Complies with Regional Value Content and Tariff Code Transformation requirements for NAFTA Preference Criterion B. |
| Battery | User-replaceable CR2032 (included). |
| Shock Resistance | MIL-STD-810g, Transit Shock, Method 516.6 Procedure IV; unit only; impact may damage replaceable impeller. |
| Sealing | Waterproof (IP67 and NEMA-6) |
| Battery Operational Temperature Limits | 0° F to 140 ° F | -18 °C to 60°C Measurements may be taken beyond the limits of the operational temperature range of batteries by maintaining the unit within the operational range and then exposing it to the more extreme environment for the minimum time necessary to take reading. |
| Storage Temperature | -22.0 °F to 140.0 °F | -30.0 °C to 60.0 °C. |
