How to choose physical values monitoring system?
THERE ARE MANY WIRELESS MONITORING SYSTEMS AVAILABLE ON THE MARKET. WHAT TO CONSIDER WHEN CHOOSING?
First of all, it should be noted whether the transmission method is based on the standards provided for wireless sensors. Wireless sensors should use transmission protocols dedicated to sensor solutions: Bluetooth LE, Zigbee, Sigfox, LoRa, NB-IoT, LTE Cat M. The use of these techniques is a condition for building a future proof installation. Currently, many solutions use wireless communication standards not adapted to the sensor networks (e.g. WiFi).
VERY OFTEN THE INVESTOR'S REQUIREMENT IS TO SAVE DATA ON LOCAL SERVERS, ARE THERE ANY ADVANTAGES OF SUCH A SOLUTION?
Disadvantages are easy to mention, advantages are hard to find. The most important problems associated with choosing such a solution are:
• high installation price associated with the purchase of servers
• costly operation related to the supervision of servers and software
• danger of failure and data loss
• a problem with the organization of supervision by people outside the facility
SO WHAT ARE THE ADVANTAGES OF USING A CLOUD PLATFORM?
First of all, they don't have the disadvantages listed above. In addition, the costs of implementing and operating such systems are much lower. We have met the installation cost estimates several times in the form of local data storage, which were up to 10 times higher than "cloud monitoring". Cloud-based installations work with virtually no maintenance, while systems based on local servers require full-time care for installations with more than 100 sensors.
WHAT CAN YOU RECOMMEND FROM YOUR OFFER?
We can recommend a solution based on Bluetooth Low Energy. It consists of wireless sensors, gateway and Efento Cloud platform. Data from sensors is transferred to the gateway, and from it directly to the platform in the "cloud" consisting of several servers, for security located throughout Europe.
