How to Monitor Warehouse Temperature and Humidity
Importance of Warehouse Temperature and Humidity Monitoring
Many warehouse owners overlook the importance of monitoring temperature and humidity in the warehouse. Failure to monitor the environment in the warehouse area leads to unexpected expenses. Loss of inventory due to damage caused by excessive humidity, temperature or water leaks results in lost inventory.
What damage can be caused?
Excessive humidity in warehouse areas can lead to mildew and mould growth on products, shelves, boxes and walls. Condensation causes rust and accelerates corrosion of metal parts. Increased insurance costs due to customer claims or returns.
Humidity changes over the course of the day. Often daytime humidity can be perfectly reasonable, and in the 30% range. However, at nighttime, it can easily increase to 70-80%. This means 24/7 monitor of humidity is essential, with alerts when it is out of prescribed range.
When the quality and purity of the products rely on correct storage it is critical that a warehouse temperature and humidity monitoring system is employed.
Types of warehouse storage
When the quality and purity of the products rely on correct storage it is critical that a warehouse environmental monitoring system is employed.
Ambient temperature refers to products that can be stored at the warehouses’ natural condition.
Air-conditioned storage is where products should be stored between 56°F and 75°F. Confectionary is a typical example of this.
Refrigerated storage means a required temperature range of 33°F – 55°F.
Frozen storage requires temperatures of 32°F and below.
The above environmental warehousing conditions can be implemented through different storage methods. Temperature-controlled storage utilizes heating or cooling systems. These maintain a temperature required for the stored products. Climate controlled storage, often used interchangeably with temperature-controlled, includes dehumidifiers or humidifiers. Not only is temperature-controlled but so is the humidity.
Warehouses that provide temperature or climate-controlled storage will have an annual audit. This temperature mapping allows systems to be adjusted to maintain the required environmental conditions. This is a reactive measure.
A proactive measure would be a permanent monitoring system, that includes data logging, reporting and alerts. Sometimes a wall-mounted LCD display is incorporated. Real-time monitoring and alerts when temperature or humidity is outside of the required parameters can save thousands of dollars in lost stock.
Warehouse temperature monitoring systems
Wireless sensor monitoring systems are easy to install in a warehouse environment. Typical problems usually include power for the sensors and restrictions on running cables due to snagging on forklifts. AKCP provides a Wireless Tunnel™ LoRa based wireless warehouse temperature and humidity monitoring system. Easily deployed, with 10-year battery life. Centralized monitoring and alerts with AKCPro Server.
