Thermal Camera for Agriculture | WIRIS Agro UAV Camera

Agriculture-Specific Design — What Distinguishes the WIRIS Agro from Other WIRIS Drone Cameras

The WIRIS Agro is the only member of the Workswell WIRIS drone camera range designed specifically for agricultural applications. Five features distinguish it from the WIRIS Pro, Pro SC, Enterprise, and Enterprise SC: its ~450 g weight is the lightest in the WIRIS range, directly extending agricultural drone flight time and area coverage per battery charge; its −25°C to +135°C temperature range is optimised for the ambient-to-plant-surface temperature window relevant to crop canopy monitoring, providing finer temperature resolution within this range than systems with wider upper limits; its Wi-Fi interface enables wireless field-edge data review and camera configuration without cabling the drone; its microSD storage enables affordable, field-swappable media management for high-volume agricultural survey operations; and its custom agriculture-specific colour maps — WaterStep for water stress visualisation and CropStep for crop health visualisation — make field-level thermal patterns immediately interpretable to farmers and agronomists without specialist thermal imaging expertise.

How Thermal Imaging Detects Crop Water Stress

The physics underlying the WIRIS Agro’s crop water stress detection is straightforward: well-irrigated plants maintain active transpiration through open stomata, which cools leaf surfaces through evaporative heat removal. When plants experience water deficit, they close stomata to conserve water, reducing transpirational cooling and causing canopy temperature to rise above that of well-watered plants in the same field. The WIRIS Agro’s ≤30 mK (0.03°C) thermal sensitivity reliably detects these temperature differences — typically 1–5°C between stressed and non-stressed plants — across the full field view from UAV altitude, identifying under-irrigated zones, blocked drip emitters, and irregular sprinkler coverage patterns that ground-level inspection would miss.

Agriculture-Focused Thermal Imaging with WaterStep and CropStep

Captures crop canopy temperature variations with agriculture-specific WaterStep and CropStep colour maps that make water stress and crop health patterns immediately interpretable to farmers and agronomists in the field. The −25°C to +135°C temperature range is optimised for the ambient-to-crop-surface window, providing finer temperature resolution within the crop monitoring range than systems with higher upper temperature limits.

Radiometric Data Accuracy with ≤30 mK Sensitivity

Provides per-pixel absolute temperature measurement with ≤30 mK sensitivity, reliably detecting the 1–5°C canopy temperature differences between water-stressed and well-irrigated crop areas that characterise early water deficit before visible wilting symptoms develop. The calibrated radiometric data supports quantitative canopy temperature analysis for research-grade agricultural experiment documentation as well as operational farm management.

Custom Vegetation Indices — NDVI and NDRE

Supports real-time NDVI and NDRE vegetation index computation, enabling combined thermal stress and vegetation health mapping from a single survey flight. NDVI provides broad green vegetation density and health assessment; NDRE provides greater sensitivity to early-stage chlorophyll variation and is more effective for detecting nutrient deficiency in dense canopy crops where NDVI saturates. Together they give agronomists and researchers a comprehensive picture of crop condition from one WIRIS Agro survey flight.

Lightest WIRIS Payload at ~450 g — Maximum Agricultural Flight Time

At approximately 450 g, the WIRIS Agro is the lightest payload in the Workswell WIRIS drone camera range — approximately 40–50% lighter than the WIRIS Pro, Pro SC, and Enterprise SC. This weight advantage directly extends agricultural drone flight time per battery charge, increasing area coverage per survey session and reducing the cost per hectare of thermal precision farming data. Agricultural drone service providers covering large farm areas benefit directly from the lower payload weight in operational efficiency and revenue per flight session.

Real-Time Aerial Insights via Wi-Fi and Live Streaming

Delivers live thermal and vegetation index data for immediate agricultural decision-making. Wi-Fi connectivity enables wireless field-edge camera configuration and preliminary data review on a tablet or laptop between flights without cabling the drone — well-matched to the agricultural field operation workflow where the UAV is launched and retrieved at the field boundary and the operator is the farmer or agronomist rather than a specialist drone technician.

Durable and Field-Ready for Agricultural Operations

Built to withstand outdoor farming conditions, dust, moisture, and continuous UAV operations across Indian agricultural environments including hot and humid summer conditions in tropical farming regions, dusty dry-season field surveys, and high-humidity monsoon-adjacent operations. The microSD storage system is field-swappable and affordable to manage across high-volume multi-farm survey operations.

Crop Health Monitoring

Identifies water stress, nutrient deficiencies, and plant disease before visible symptoms appear across the full field from UAV altitude:

• Nutrient deficiency mapping: NDRE index mapping sensitive to early-stage chlorophyll reduction from nitrogen or other nutrient deficiency, enabling targeted variable-rate fertiliser application in deficient zones rather than uniform blanket application
• Disease and pathogen detection: thermal and vegetation index anomaly mapping identifying disease outbreak zones from their thermal and chlorophyll expression for early containment and targeted fungicide/bactericide application

Irrigation Management

Detects over- or under-irrigated areas to optimise water distribution across large agricultural fields:

Precision Farming

Enables targeted fertiliser and pesticide application based on aerial thermal and vegetation index data, reducing input costs and environmental impact:

• Variable rate application (VRA) zone mapping: generation of thermal and NDVI/NDRE-based management zone maps that define areas within a field requiring different fertiliser or pesticide rates, enabling VRA controllers to apply the right amount at the right location
