Business Challenges
Before implementing the solution, Bigfoot Cold Storage faced several operational challenges that affected refrigeration efficiency and product quality. The absence of an automated Temperature Monitoring System made it difficult to maintain stable storage conditions and respond quickly to environmental changes.
Temperature Fluctuations
Maintaining consistent temperatures across multiple cold storage chambers was difficult, increasing the risk of product spoilage.
Humidity Control
The absence of continuous humidity monitoring made it challenging to maintain ideal storage conditions for perishable products.
Hazardous Gas Safety
Cold storage facilities lacked continuous monitoring of hazardous gas concentrations, increasing safety risks for personnel and delaying the detection of potentially dangerous conditions.
Rising Energy Consumption
Continuous refrigeration operations resulted in increasing electricity costs and reduced overall energy efficiency.
Manual Monitoring
Temperature and humidity were monitored manually, delaying the detection of abnormal conditions and corrective actions.
Limited Operational Visibility
Operators lacked centralized, real-time visibility into environmental conditions and refrigeration system performance.
Proposed Solution
Niraltek implemented an integrated Temperature Monitoring System designed specifically for cold chain applications. The Temperature Monitoring System continuously captures environmental data, enabling real-time monitoring, automated alerts, and centralized control.

- Historical Data Analysis
The solution continuously monitors temperature, humidity, and hazardous gas levels across two cold storage chambers using dedicated Sensor Nodes (Slave Devices) connected to industrial-grade sensors.. The collected data is transmitted wirelessly to the NTS IoT Gateway (Master Gateway), which supports Wi-Fi, Ethernet, and GSM SIM connectivity for reliable communication with the centralized monitoring platform. This enables real-time visualization, instant alerts, historical reporting, and improved operational control.
Solution Architecture
The solution is built on a scalable Industrial IoT architecture that integrates the Temperature Monitoring System and Hazardous Gas Monitoring System with LoRa wireless communication and the NTS IoT Gateway for secure and reliable data transmission.
NTS IoT Gateway (Master Gateway)
The NTS IoT Gateway acts as the master device of the monitoring system, receiving data from slave devices through LoRa wireless communication and securely transmitting it to the cloud platform. Supporting Wi-Fi, Ethernet, and GSM SIM connectivity, it provides reliable communication even in industrial environments where network availability may vary.
Sensor Nodes ( Slave Devices)
Each cold storage chamber is equipped with a dedicated Sensor Node (Slave Device) that collects temperature, humidity, and hazardous gas data from connected industrial sensors before transmitting it to the NTS IoT Gateway via LoRa communication.
LoRa Wireless Communication
LoRa technology provides reliable long-range wireless communication between the Sensor Node and the NTS IoT Gateway, reducing wiring complexity while ensuring stable data transmission throughout the facility.
Temperature & Humidity Sensors
Industrial-grade sensors continuously monitor environmental conditions inside each chamber, ensuring stable temperature and humidity levels for safe product storage.
Central Monitoring Platform
The centralized monitoring dashboard provides real-time visualization of temperature, humidity, hazardous gas levels, energy consumption, historical trends, and alarm notifications, enabling operators to monitor all critical parameters from a single interface.
Hazardous Gas Sensors
Industrial hazardous gas sensors continuously monitor gas concentrations inside the cold storage facility. When abnormal gas levels are detected, the system immediately generates alerts and notifications, helping improve worker safety and enabling rapid corrective action.
