The Controlant's Monitoring System is an automatic wireless monitoring system , which is used in various applications where automatic measurements of to measure environmental variables (e.g. temperature, humidity) are requiredlike temperature and humidity.

The basis of the system is a star-shaped wireless network where multiple wireless loggers can transmit measurements to a gateway unit which sends the data . The gateway unit then transmits the measurements (data) to a central database server via the mobile network. The real-time data can then be accessed from an internet-connected computer from a web browser interface.

Controlant wireless loggers run on a battery. The gateways have a rechargeable internal backup battery which that can keep the system running for 12-24 hours (depending on usage) in case of power failure. The battery is a rechargeable lithium-ion battery.

Multiple loggers can be located on each location , connecting and can connect to one or more gateways. Data The data from multiple locations is gathered stored in a database, where customers can access it in a single interface.

Figure 3: Block diagram of the Controlant wireless system

A functional block diagram for the CO 13.01 wireless logger is shown in Figure 3. The RF module CC1101 is a low-power sub-1 GHz RF transceiver operating in the 868 MHz to 915 MHz ISM band.

The system has two operating modes. The first operating mode is at a symbol rate of 4.75 kbps, and a bit rate of 38 kbps. GFSK modulation is used with 20 kHz deviation. This operation mode is used for all communications in the 868MHz band as well as for FHSS mode in the 915 MHz band. The second operating is at a symbol rate of 475 bps, and a bit rate of 4 kbps. 2-FSK modulation is used with 550 kHz bandwidth. This operation mode is used for all synch package communication in the 915 MHz band.

A 3.6 VDC battery is supplied to the RF module. The module transmits with a maximum power of 11 dBm into an external antenna. This module does not transmit for more than 54 ms over any 1 s time period and fulfills all duty cycle limits on the 868MHz band and uses 121 channels for FHSS in the 915 MHz band with 200 kHz channel spacing and 75 kHz channel bandwidth (20 dB).

Logger Operation

The purpose of the Controlant wireless logger is to measure environment centralized database and accessible to users via Controlant's cloud-based platform. 

Logger Operation

Controlant's wireless IOT loggers measure environmental variables such as temperature and humidity. The loggers automatically transmit measurements to a nearby gateway, which forwards the forwarding all data to a central centralized database.   The wireless sensor communicates with the gateway on the license free ISM bands (868 MHz for EU and 915 MHz for North America).

• Cellular Network (3G)
  

Controlant Gateways relies Gateways rely on 3G cellular networks to transmit loggers logger data to the Controlant cloud. Same The same rules applies apply to these radio communications as all other mobile and high frequency communications. If the signal is low or badblocked, the functionality of the system will be effected. However, the system takes that into account, store the data in the loggers itself and sends the real-time functionality may be impacted. If such an interference occurs, Controlant's loggers are programmed to store the data then transmit the data to the Controlant cloud when as soon as the cellular connection has been re-establishedrestores. 

Wall types in a warehouse can effect the signal quality as well as the device installation itself.  Further information regarding wireless installation and wall types can be found in 1.3.1 General Wireless Setup 

• Database

Simplicity and accessibility are the key elements of the Controlant online software platform. Customers have an easy and safe way to store, access and work with measurements online.

The online web interface - built around our centralized database system – offers customers access to data whenever and wherever they need it. The software solution is very flexible and suits needs from those of the pharmacist who needs to gather regular data on temperature condition of a single medicine cabin to those of the quality or logistic manager overseeing tens of businesses with hundreds of loggers.

Benefits of the online platformControlant's platform, built around a centralized database system. All data is stored in a secure cloud system in an ISO27001 certified environment to ensure stability. Data is stored for as long as required by users. 

Benefits of Controlant's online database include: 

• • • Easy access to data online

-

• • • , whenever and wherever needed
