• Identifies early signs of plant stress, nutrient deficiency, diseases, or pest infestations—often before they’re visible to the human eye.
• Enables proactive measures (targeted pesticide or fungicide application), significantly reducing reliance on chemical sprays and minimizing environmental impact.
• Supports uniform growth by guiding timely interventions across large or multi-zone farms.

With Farmonaut’s real-time crop health monitoring and NDVI (Normalized Difference Vegetation Index) analytics, even remote or large-scale farm operators can track every critical metric, improving yield and protecting crops.

5. Livestock Sensors for Health & Welfare Monitoring

Livestock and animal wearable IoT sensors are transforming animal husbandry by enabling continuous monitoring of health, behavior, and location.

• Wearable sensors collect and transmit vital signs (heart rate, temperature, movement patterns) and quickly detect illness or distress in animals, enabling early intervention and reducing livestock losses.
• GPS-enabled trackers help in managing grazing patterns, preventing theft or loss, and optimizing field use.
• Improves overall welfare and aids compliance with animal health and security standards.

Automated data collection from livestock sensors minimizes manual labor and enhances decision-making for both large-scale dairy, meat, and mixed farming operations, further enhancing productivity and profitability.

6. Smart Greenhouse Sensors & Automated Environment Control

Indoor and protected environment agriculture is evolving rapidly with the deployment of smart greenhouse sensors. These multi-sensor systems monitor and automatically regulate:

• Light intensity
• CO2 levels
• Soil nutrients
• Temperature and humidity

Automated adjustment of climate variables within greenhouses—including shading, ventilation, irrigation, and lighting—maximizes plant growth, reduces manual intervention, and supports year-round high-quality crop production.

• Yields increase significantly, as each crop receives custom microclimate conditions for optimal health.
