A new design about the integration of temperature sensor and RFID tag is provided. This is a dual-tag design, in which the temperature element is connected to one of the RFID tag antennas to form a parallel structure. In this design, some of the functions of the sensor are transferred to the RFID reader so that some components of the sensor can be cut, reducing the production costs of existing design. By defining the signal strength of the first tag as a reference value, the problem of setting a standard is solved in the temperature detection process. RF module can be used to make the energy transformation without requiring the entire design to have an external continuous power source to provide energy. In addition, experimental data proves the feasibility of this design.

A novel optical sensor for ratiometric temperature detection is devised via Ag&Mn:ZnInS quantum dots (QDs). The temperature can be read via the PL ratios of Ag-related and Mn-related PL intensity.

This Paper introduces a temperature detection system in beer fermentation. A temperature monitoring system with characteristics of bus topology structure is composed of industrial computer, temperature detector, bus converter, transmission bus and especially 1-wire digital temperature sensor DS18B20. Four-core cable is used to form a tree-like or star-like network, in which 54 digital temperature sensors existing on 18 fermentation tanks can be connected. The quantity of junction wires between temperature sensor and computer will be reduced greatly. Temperature detector provides power supply for bus converter and DS18B20 through Four-core cable. Because bus converter has used hardware fault detecting technology, the fault temperature sensor can automatically detach from the main bus and will not affect normal working of other sensor in network. So to solve the problem of a certain sensor or branch's damage causing the paralysis of entire bus. The length of detecting temperature bus can reach more than 500 meters. These all make system maintenance and expansion easy. The experiments show that this system is characterized by high intelligence, high-precision, capability of making temperature test on multi-points and compensating function. The method has a good applicable value to the temperature test.

In the present scenario due to Covid-19, the need for face mask detection applications, temperature detection and hand sanitizing are now in high demand for Railway Entrance, Airport Entrance, Office Entrance, Museums and Amusement Parks, Other Public Places and enterprises to ensure safety. These steps are now done in manual way by which the personnel may get in contact with the other personnel while sanitizing and checking temperature might not be accurate. To mitigate the problem, aiming to increase Covid-19 entrance safety, covering several relevant aspects: Contactless temperature sensing, Mask detection, Automatic hand sanitizing. Contactless temperature sensing subsystem relies on Raspberry Pi using temperature sensor,while mask detection performed by leveraging computer vision techniques on camera-equipped Raspberry Pi, then the automatic hand sanitizing is achieved by the DC motor connected with the sensor and Raspberry Pi. Any person without temperature check, hand sanitizing and mask scan will not be provided entry. Only person having the conditions satisfied by the system is instantly allowed inside, else the buzzer will alert the security about the situation, if any violation of the condition is found. From the simulation results, it is clearly observed that the proposed method has high accuracy compare to the existing methods. Thus the system provides a 100% automated system to prevent the spread of Covid-19.

Dalam situasi pandemi Covid-19, roda perekonomian harus tetap berjalan dengan mengedepankan protokol kesehatan. Melansir dari keputusan menteri kesehatan bahwa setiap kantor di Indonesia yang tetap melaksakan Work From Office selama PSBB berlangsung maka harus melakukan pengukuran suhu tubuh, menyediakan hand sanitizer dengan konsentrasi alkohol minimal 70% atau menyediakan sarana cuci tangan di depan pintu masuk. Masalah yang sering terjadi adalah pengukuran suhu tubuh masih dilakukan secara manual oleh satpam kantor, dan tidak terbiasanya para karyawan untuk menggunakan hand sanitizer. Sebagai upaya pendisiplinan karyawan, maka dirancang prototype pintu otomatis yang hanya bisa terbuka jika suhu tubuh normal dan karyawan sudah menggunakan hand sanitizer.   Deteksi suhu tubuh dilakukan menggunakan sensor suhu  MLX90614 dan deteksi objek tangan menggunakan sensor infrared. Pintu geser digerakkan oleh Stepper Motor NEMA 17, pintu secara otomatis akan terbuka ketika suhu terdeteksi normal, jika tidak maka buzzer akan berbunyi dan pintu tetap tertutup. Hasil dari penelitian ini memperoleh hasil pengujian keakuratan sensor suhu MLX90614 sebesar 96.8%, posisi tangan optimal yaitu posisi tangan menengadah dengan jarak 1cm terhadap sensor, dan volume hand sanitizer yang cukup untuk mengcover seluruh telapak tangan dewasa adalah pada delay 500 ms yaitu sebesar 2.2991 gram.   During the Covid-19 pandemic, the economics activities must go on with strict health protocols. From the recommendation of health ministry, that every office in Indonesia that still performs Work From Office during the pandemic, temperature measurements must be carried out at the entrance to the office and hand sanitizer that contains minimum of 70% alcohol or hand washing facilities must be provided as well. The problem is that body temperature measurements are still done manually by security officer, and some employees are still not familiar to use hand sanitizer periodically. As an option to make employees discipline, a prototype of automatic door is designed in this research. It can only open if the body temperature of employee is normal and the employee has used hand sanitizer. Body temperature detection is carried out by using the MLX90614 temperature sensor and hand object detection will utilize infrared sensor. The sliding door is driven by the NEMA 17 Stepper Motor, the door will automatically open when the temperature is detected normally, otherwise the buzzer will sound and the door will be still closed. From the testing results in this research, the accuracy of the MLX90614 temperature sensor is 96.8%, the optimal position of the hand is 1 cm from the sensor with looking up position. And the volume of the hand sanitizer that is sufficient to cover all adult palms with 500 ms delay is 2.2991 grams.
