Overview
Floriculture Cold Storage Monitoring with Temperature, Humidity & Door Status Sensors
In floriculture, cold storage is not just a facility it is the most critical step in protecting flower freshness, appearance, and shelf life before dispatch.
Even a small temperature drift, humidity imbalance, or frequent door opening can reduce quality silently and lead to product rejection at the next stage of the supply chain.
To maintain stable cold room conditions and avoid reliance on manual checks, this customer implemented a complete floriculture cold storage monitoring system using temperature monitoring, humidity monitoring, and door status tracking. The goal was simple: ensure every batch of flowers stays within the right environmental range, with clear visibility of conditions throughout the day and night.
This case study explains how continuous monitoring helped improve consistency, reduce operational risk, and maintain high-quality storage conditions for high-value floriculture inventory.
The starting point
Problems Faced in Floriculture Cold Storage
Floriculture cold storage is not like storing packaged goods.
Flowers are living products they keep reacting to temperature and humidity even after harvest.
So the problem is not “keeping the cold room ON.”
The problem is keeping it stable while real work is happening.
And that instability is exactly where the financial loss starts.
01
Imprecise Control Loop
The legacy setup relied on basic thermostats and wide-tolerance hygrometers, making it difficult to consistently maintain 0°C to 4°C and 90% RH (±2%).
02
Destructive Humidity Fluctuations
Even short humidity drops caused flowers to dehydrate, directly reducing freshness and vase life.
03
High Shrinkage & Financial Loss
This combination of poor accuracy and slow correction resulted in repeated product quality loss, shrinkage, and avoidable revenue impact.
04
Data Lag & Blind Spots
Limited sensor coverage missed temperature and humidity pockets inside the room, forcing teams into reactive manual adjustments that were slow and often ineffective.
The approach
The Solution: LoRaWAN-Based IoT for Automated Cold Storage Monitoring & Control
To eliminate temperature and humidity drift in the floriculture cold storage, we deployed a LoRaWAN-based IoT monitoring system designed for continuous environmental tracking and faster corrective action.
The solution combines temperature monitoring, humidity monitoring, and door status sensing to capture the real conditions inside the cold room including the fluctuations caused by frequent door activity and airflow imbalance.
01
Real-time Humidity Monitoring
LoRaWAN sensors continuously track humidity levels to maintain ideal storage conditions.
02
Temperature Control Automation
Automated alerts and control mechanisms adjust cooling systems to keep temperature stable.
03
Humidifier Motor Management
IoT-enabled control of humidifier motors to prevent over- or under-humidification.
04
Remote Data Access
Real-time monitoring and control via cloud dashboard for managers and operators.
05
Preventive Alerts
Instant notifications for deviations from set thresholds, reducing flower spoilage risk
06
Reliable Power & Enclosure
IP67-rated, solar-assisted setup ensures continuous operation in harsh conditions.

Cold Storage Deployment Diagram: Sensor Placement & Coverage
Deployment was planned with one simple goal: capture the real cold storage conditions where flowers are actually stored, not just where it’s convenient to mount a sensor.
We placed the temperature and humidity sensors inside the cold room at practical monitoring points so they reflect the true environment experienced by the product during storage and dispatch cycles.
In this deployment
Installed inside cold rooms for precise environmental tracking.
Automates the humidifier motor operation based on humidity data.
Positioned at central locations to collect data from all nodes and forward it securely to the cloud platform.
Provided operators with live status, historical data, and performance analytics for parking utilization and sensor uptime.
What stood in the way
The Real Challenges Inside a Floriculture Cold Room (And Where Quality Loss Begins)
01
Unstable Temperature Control
Frequent fluctuations inside the cold room led to premature wilting and reduced flower shelf life
02
Inconsistent Humidity Levels
Lack of real-time humidity tracking caused the flowers to dry out or retain excess moisture.
03
Manual Operation of Humidifiers
Operators had to switch humidifiers on/off manually, often leading to delayed action and improper moisture control.
04
No Remote Monitoring Capability
The absence of a connected system made it impossible to check real-time conditions without being physically present.

Why LoRaWAN Matters Here: Stable Monitoring Without Wi-Fi Dependency
Enhanced Flower Shelf Life
Maintaining ideal humidity and temperature levels extended the freshness period, reducing spoilage and waste.
Automated Humidifier Control
The humidifier automatically adjusted based on real-time humidity data, eliminating manual intervention.
Real-Time Monitoring
The farm owner could now monitor cold storage conditions remotely through the Macsync web dashboard.
Energy-Efficient Operations
Optimized on/off control reduced power consumption and improved compressor lifespan.
In closing
Conclusion: Protecting Flower Freshness with Stable Temperature, Humidity and Door Control
In floriculture, cold storage performance is not measured by whether the cooling unit is running it’s measured by how consistently the room maintains the right environment for every batch of flowers.
By implementing LoRaWAN-based temperature, humidity, and door status monitoring, the client moved from periodic manual checks to continuous visibility of real cold room conditions. This helped identify hidden fluctuations, reduce unnecessary exposure during door activity, and maintain stable storage conditions throughout daily operations.
The result is a cold storage setup that is easier to manage, easier to control, and far more reliable for protecting flower freshness, reducing shrinkage, and avoiding avoidable financial loss.
This project was not about fixing a failure it was about building a system that keeps performance stable every single day.
