We are happy to announce that we are offering a Special 50% Discount for a Beginner Account (previously RM 100 per year) to celebrate FAVORIOT‘s 1st Anniversary.  The offer is valid from June 1 to August 31, 2018. The Beginner Plan is very suitable for University students who have been assigned or chose IoT project as their Final Year Project. A single device such as Raspberry Pi or Arduino that collects data from several connected sensors can stream to an IoT platform. This will simplify the development and reduce the headache of building own web server or platform to connect the IoT device. A simple dashboard is provided to visualize the measurements. This plan is also suitable for an individual developer or hobbyist that would like to familiarize with IoT platform, conduct self-learning or participate in IoT Hackathons. At RM 4.17 (USD 2.50) per month, you can become the next Generation-IoT and be on your way to be one of the rare talents in the job market today!

Recently UTHM participated ITEX2018 and won Silver for a project entitled “Automatic Electromagnetic Radiation Level Detection and Monitoring System“.

 In some cities, mobile phone Base Transceiver Stations (BTSs) are found almost at every 500 m interval, and in other cities where there is no restriction on the location of the towers, more than 30 cell towers can be seen within 1 km. Since more users are emerging every day, the proliferation of mobile Base Transceiver Station (BTS) or mast is of great concern. The radiation emitted from the numerous antennas mounted on the mast of the cell are also of great concerns to the populace, especially people who live close to them.

Therefore, it is compulsory to extract the value of Electric (E) -field (volts/meter) from the individual frequency components of the GSM bands such as 0.9 GHz, 1.8 GHz and 2.1 GHz to be compared with ICNIRP level. Therefore, the main interest for this project is to measure the mobile signal from the base stations, which are mostly close to the residential area covering the GSM bands of 0.9 GHz, 1.8 GHz, and 2.1 GHz.

Currently, the radiated emissions from the GSM tower are detected by the spectrum analyzer which mobile frequency band network systems. However, the spectrum analyzer does not have any provision to broadcast or transmit any information obtained in the field over the internet. In addition, the data measured by spectrum analyzer is offline and not a real time results. It is difficult to give a real picture of the electromagnetic (EM) radiation level in the intended environment. Electromagnetic radiation should not exceed the radiation limit proposed by ICNIRP.

Therefore, this maximum allowable E-field limit has to be followed for human safety. Electromagnetic radiation readings below the radiation limit indicate that the radiations in that specific area are within the safety levels. Therefore, an automatic system capable of measuring the electric (E) fields at the mobile phone frequencies (0.9 GHz, 1.8 GHz, and 2.1 GHz) is designed as shown in Figure 1. These E-field data will then be “pushed” into the internet for continuous monitoring (24 hours a day). The designed unit acted as receiver / EM mobile sensor, consist of an antenna and detector that can produce an accurate DC voltage and eventually convert it into electric (E) field with calculated antenna factor (AF).

Figure 1: Overall system layout

A radiation detector complete system as shown in Figure 2. It consists of receiver sensor (antenna), 3V circuit, WIFI shield, and microcontroller. The rectangular patch antenna is the receiver to receive a signal from the base transceiver station. The microcontroller received the input voltage from the detector and convert it to E-field value. In addition, WIFI shield is the medium hub to connect the Arduino to FavoriotPlatform through Internet. The extracted E field information would be plotted for each frequency in the FavorIoT Platform. As a result, the user can access the data via any internet enabled devices. The complete system will be placed in the proposed packaging as shown in Figure 3.

Figure 3: Proposed packaging for the complete system

The new system has been calibrated and compared with an existing system in the market. Figure 4 shows the comparison between the existing system (using spectrum analyzer and horn antenna) and our product. Based on the results, the E field strength values show a good agreement as the percentage of deviation is quite small which is an average of 2%. The uncertainty of the measurement is ±4.6478 dB. Therefore, E field values for 0.9 GHz, 1.8 GHz, and 2.1 GHz are valid for the measurement as the maximum deviation is 2.4 dB, which is still in the range of the uncertainty. Therefore, the fabricated rectangular patch antenna can be used to detect mobile electromagnetic radiation accurately.

The E field strength was calculated and the real-time data measurement was stored and displayed in the Favoriot platform. Figure 5 shows the E field strength data for operating frequencies of 0.9 GHz, 1.8 GHz, and 2.1 GHz. 121.28 dBuV/m is the maximum radiation reading shown in Figure 5. The reading does not exceed the radiation limit proposed by ICNIRF level, which is 155 dBuV/m. The result and data can be accessed by the end user using through Favoriot Platform.
