How to decide the sampling interval?

The frequency of data collection is determined by the sampling interval. e.g. If the temperature is recorded in every 10 seconds, then the sampling interval is 10 seconds. The customer can set the sampling rate from 5 seconds to 1 hour, with a +/- 0.1-degree Celsius accuracy.

We can set higher and lower thresholds of temperature and humidity on the device as well as the delay duration. It will dial 10 operators in succession until one of them picks up the call if the parameters go beyond these preset ranges for the specified amount of time. When it answers the call, it plays a recorded voice message describing the fault’s nature and location. You may consider the following points.

  1. For a narrow range of temperature, a lower sampling rate is required. eg. for a cold room of 2-8 °C, a sampling rate of 3 minutes may be required whereas for a warehouse of 15-25°C a sampling interval of 10 minutes may be sufficient.
  2. Another criterion is permitted excursion period. eg. You do not want the temperature to go above 8°C for more than 1 minute. Hence, you should select a sampling interval of 60 seconds or less. The logic is that you need to monitor the temperature very closely.
  3. For cold storage of -20°C, a sampling interval of 15 or 20minutes also may be sufficient.
  4. Typically for medicines, we recommend a sampling interval of 3 minutes.

 

Technical Details of the warehouse monitoring system

  2. Using an Internet connection and browser, the customer can configure, set up, and manage Data Loggers.
  3. We offer a free, password-protected web storage service.
  4. The customer can choose a sampling rate from one second to one hour.
  5. A local siren can be connected, and the duration of the alarm can be programmed.
  6. The system uses a regular power source and a battery backup to prevent power outages. When a power outage happens, the device will not lose data.

How to decide the number and locations of temperature sensors in a warehouse and cold room?warehouse-monitoring-alert-systems

In a huge warehouse or cold room, it is difficult to decide the ideal locations to be monitored and hence the sensors’ placements for monitoring.

To decide the locations and number of sensors, the following guidelines may be followed:

  1. To determine the temperature distribution, it is ideal to conduct a temperature mapping study at first.
  2. Determine the hottest and coldest points of an area.
  3. Discover if there are any additional hot and cold spots.
  4. Highlight these points on the area’s layout drawing.
  5. Since the above-mentioned points are crucial, they need to be monitored constantly.
  6. If any significant area is missed from the locations thus defined, one or two sensors should be distributed there.
  7. Typically, 10 sensors will be needed for a warehouse with an ideal temperature distribution that is 3000 square meters in size and 10 meters high.

 

Temperature Monitoring Software

The software continuously collects readings from the data loggers for the whole warehouse or cold room as installed. The following tasks are performed by the software:

  1. Setting distinct alert parameters for each sensor.
  2. When there are alert conditions, email alerts will be sent.
  3. It shows graphs and charts for various devices and locations.
  4. Multiple devices can be monitored on a single screen.
  5. It sends the reading summary to 4 Email addresses on a regular basis (1 hour to 24 hours can be programmed).
  6. To upload the data on a regular basis, we can set up an FTP service.
  7. The software allows us to set the sampling interval.

Phone call, SMS and Email alert system for temperature monitoring systemsphone-sms-alert-system-for-warehouse

We can connect several other crucial parameters to the same voice call alert system in addition to over-temperature and humidity alerts. Since this alert system uses a SIM card to operate, a local phone connection is not necessary.

The following critical parameters can be tracked:

  1. Compressor failure alert – to track whether the cooling units’ compressors malfunction.
  2. Power Failure Alert – makes a call if the power supply goes out.
  3. Door Open Alert – alerts if a refrigerator or cold room door is left open for a predetermined amount of time.
  4. Water Leakage detection – sends out an alert in the event of water leak.
  5. Gas leakage Alert – a phone call or SMS alert will be generated, if any gas leak is detected.
  6. Smoke Alert – A phone call or SMS alert gets generated in case of smoke or fire.

How to select a temperature/humidity monitoring and recording system for a warehouse?

A brief guide to choose the best recording and temperature monitoring system is provided below. You are welcome to get in touch with us for a free consultation, and the list is only meant to aid in your understanding.

  1. Firstly, decide whether you need to record only temperature or humidity record is also required. The items being stored are the main factor in this. For ex., for a pharma industry, the humidity must be lower than 65%. For such requirements, humidity monitoring is also important. Similarly, fertilizers kept in porous packaging require an optimum humidity environment. If you’re unsure, you can ask the manufacturer of the products you’re storing.
  2. Next, you must choose the alerts you need to receive. This means that you must determine whether you need only email alerts, SMS alerts, or both phone and email alerts.
  3. The type of communication is among the most crucial factors to examine. We offer a variety of channels including wired Ethernet, WiFi, and radiofrequency. Use radiofrequency devices for warehouses where you do not want to pull wires. They typically do not have a display screen, so they have a longer battery life. A power supply connection is necessary because a display screen uses a lot of electricity.
  4. A Wi-Fi connected monitoring system is an option if you have a power source available and Wi-Fi access in the warehouse. You may also choose a wired Ethernet device if your warehouse has LAN ports.
  5. You might specifically observe that installing Wi-Fi and wired Ethernet devices in the middle of the warehouse and in the racks is challenging. This is so because they both require a wire or wires. It is challenging to run wires across the racks. But since radio frequency-based devices run on batteries, they can be installed anywhere in the warehouse right away.
  6. Radiofrequency devices do, however, have drawbacks. The communication between the devices won’t be effective in spaces with tall racks. You will need to add a few more receivers in this situation, which is an expensive process. Additionally, depending on the location, you might need to add a new receiver when you later add a new device. The early stages of this are unpredictable. The same holds true for a Wi-Fi device. However, an extra Wi-Fi router is not a major concern because it only costs less than US$ 50.00 only.
  7. As with all temperature monitoring systems, you should confirm that it will function in the event of a power outage and determine whether you will lose data if you do. This decision can be made based on how dependable your power supply is.
  8. The system’s monthly or yearly fee structure is one of the most crucial commercial factors. There are vendors who offer the warehouse monitoring system for a low price but then charge you high recurring fees.
  9. Please check the prices for calls and SMS alerts as well.
  10. You may need to look up your organization’s internal IT policy regarding data storage. Most operators keep their data on cloud-based platforms. Some large organizations, however, do not want any data to be kept off their server. You ought to be able to purchase the complete software in this situation and install it on your own server which is a significant drawback for many of these systems.
  11. Your life will be easier if you can automatically receive monthly recorded data to your email. If not, you need to log into the server and download the information for a certain time frame. This feature is optional and is only considered nice to have.
  12. You can also find out how long the supplier will keep your data on file in their system. Companies have different policies, such as whether to keep data for one year, five years, etc. Many businesses offer lengthy storage periods, like five years.
  13. For a battery-powered device that doesn’t require an external power source, you can prefer to get a warning when the battery is running low.
The above list gives an overall idea of various essential requirements. You may list out your priorities and select a suitable supplier. We have different types of devices meeting most of the above requirements.
