Digital Temperature Sensor

An EEPROM (electrically erasable programmable read-only memory) reprogrammable fuse for trimming a digital temperature sensor is designed in a 0.18-µm CMOS EEPROM. The fuse uses EEPROM memory cells, which allow multiple programming cycles by modifying the stored data on the digital trim codes applied to the thermal sensor. By reprogramming the fuse, the temperature sensor can be adjusted with an increased trim variation in order to achieve higher accuracy. Experimental results for the trimmed digital sensor showed a +1.5/−1.0 ℃ inaccuracy in the temperature range of −20 to 125 ℃ for 25 trimmed DTS samples at 1.8 V by one-point calibration. Furthermore, an average mean of 0.40 ℃ and a standard deviation of 0.70 ℃ temperature error were obtained in the same temperature range for power supply voltages from 1.7 to 1.9 V. Thus, the digital sensor exhibits similar performances for the entire power supply range of 1.7 to 3.6 V.

Early Fire Detection

Lately, there are frequent fires caused by human factors. Because we cannot predict the process of fire in advance. And the delay in knowing the occurrence of a fire is very fatal to the safety of human life and property. With advances in technology, we can overcome fires by making early fire detection devices. With the presence of temperature and smoke detectors, we can detect fires as early as possible and be delivered quickly via alarms and SMS gateways. The main component of this fire detector is the Arduino Uno. This Arduino uno acts as the brain of the fire detection device. This tool works based on the detection of the temperature condition by the DHT11 temperature sensor, which is when the temperature is above normal, an alert notification will be sent via the SMS gateway and so will the MQ2 smoke and the buzzer will sound as a warning alarm.

Telecommunication plays the vital role in the human life and has become an integrated part of the society. The rapidly growing information and communications technology and increasing competition in telecommunication markets triggers the telecom operators to extend their networks and services to their potential customers in different geographical locations. It necessitates them to install repeaters and communication towers powered by standalone Photovoltaic system in remote rural areas. This paper presents optimization of standalone photovoltaic system maximizing reliability in one of such remotely located Palethar Repeater Station of Nepal Telecom situated in Dadeldhura district of Far-western region. The optimization is carried out using Genetic Algorithm in MATLAB software for given load profile enhancing reliability of the system with maximum reduction of overall system cost. The loss of power supply probability (LPSP) is considered for reflecting the reliability of the system. The paper discusses different optimal configuration of standalone PV system under various values of LPSP after optimization.

India’s keystone is Agriculture. Around 70 percent of India’s revenue comes from Agriculture. Conversely the population of India amplifies each and every day which requires efficient and well planned decision making techniques for the production of crops. In this research paper we find the intensification of the structures which prevent destruction of crops due to uneven and heavy rainfall. The goal is achieved by the concept of Embedded System design using IOT technology. This is done automatically without any human interference. Here we first identifies the water level in the agriculture field during rainfall by using water level sensors , if the water level exceeds there limit that will cause spoilage of crop then the device are automatically cover the agriculture field. It also identifies the temperature of the crops by using temperature sensor during the sunny days, if the heat causes spoilage of crops due to intensive sun rays then the device will automatically covers the agriculture field. After covering the agriculture field it will send the alert message using GSM module to the farmer and simultaneously the water of rain is collected through piles that will be reuse later for irrigation. To achieve this we use microcontroller , Solar panels, GSM module, DC motor, sensors, Switched-mode power supply (SMPS), Rechargeable battery

Background: Human life is enriched by mechanical, recreational and innovative activities performed by an individual. Disability is a complex phenomenon, reflecting the interaction between features of a person’s body and the society in which he or she lives. Quality of life is defined by a subjective evaluation of the life circumstances of an individual with respect to his/her values. The objective of the study was to study the prevalence of physical disability and their economic dependence and quality of life in Orathur rural population.Methods: Data was collected by house to house survey of rural population, Orathur, Cuddalore district, Tamil Nadu through pre structured questionnaire and clinical examination .The tools used include interview schedule and sickness impact profile (SIP) scale with modification. Data was analyzed statistically.Results: A total of 4508 population were surveyed in this study to find out the prevalence of disability and burden of disability. Totally 308 physically disabled persons were identified (6.8% prevalence rate). It was found that visual disability was most common disability. Economic dependency and impact on quality of life was found to be more in visual disability than other types of disability. Information on extent of impact of disabilities is required to formulate future policies aiming at improving quality of life of disabled people and making them economically independent.Conclusions: Visual disability was the most prevalent disability in the present study and Cataract being the leading cause. Vocational rehabilitation measures specifically for rural disabled people should be initiated by government and non governmental agencies to improve the economic status.

Thin-film platinum resistance thermometers of various designs and performance are widely used in various industries. The temperature measurement range of these sensors is from -200 °C to +600 °C. A functional model of a portable digital temperature meter in the range from -50 °C to +300 ℃ based on the L416 sensor type Pt100 is proposed. The optimal circuit solution for connecting the L416 sensor to the Winston measuring bridge was selected. The proposed circuit solution is suitable for power supply from autonomous DC sources, which allows for miniaturization of the device and contributes to energy efficiency. The amplification of the output voltage of the amplifier in the entire operating range of the analog-to-digital converter following the operating range of the temperature sensor has been performed, which allows obtaining the maximum resolution of the analog-to-digital conversion when measuring temperature. A functional model for converting the resistance of a temperature sensor into a digital code has been developed. The functional model shows that the source code of the analog-to-digital converter does not depend on the supply voltage of the circuit, thus realizing the stability of the function of converting the resistance of the sensor into the value of the code of the analog-to-digital converter. The sensor has a normalized characteristic of the dependence of resistance on temperature, so a precision resistance box MSR-60M has been used to calibrate the circuit of the temperature meter. With the help of the resistance box MSR-60M, it is possible to calibrate the circuit of the temperature meter with an uncertainty of 0.07 °C. Keywords: temperature meter; RTD; Pt100; Winston bridge; ratiometric power supply.
