This paper presents a system of remote, real-time and on-line monitoring method of the power equipment's infrared/visible image. Based on this system and infrared theory, a corresponding infrared radiation (IR) temperature measurement is proposed. The modified method to raise the measurement precision has been put forward, including the revision of affects of emissivity, ambient temperature and atmospheric...
In this paper we design and implement an embedded home surveillance system with zero alert power using a photovoltaic array. Traditional surveillance systems suffer from an unnecessary waste of power and the shortcomings of memory conditions in the absence of invasion. In this design we use Pyroelectric Infrared sensors (PIR) and pressure sensors as the alert group whose power is supplied by the photovoltaic...
A miniaturized semiconducting metal oxide NO2 gas sensor with integrated micro heater is reported in this paper. The sensor has the size of 1×1×0.4 mm3 and detects NO2 based on the electrical conductance change of porous nanoparticles WO3 thin film, which is deposited on the interdigitated Pt electrodes. Integrated micro heater designed to provide the operating temperature above...
In this paper we design and implement an embedded surveillance system by use of multi-frequency ultrasonic sensors with multiple Pyroelectric Infrared sensors (PIR). The ultrasonic sensor module consists of a transmitter and a receiver which are placed in a line; however, ultrasonic sensors with the same frequency are disturbed by crosstalk with each other and have a high miss rate. To overcome these...
In this paper we design and implement an embedded surveillance system with multiple Pyroelectric Infrared sensors (PIR) and ultrasonic sensors which turn on the embedded surveillance system according to the signals triggered by their majority voting mechanism (MVM). The PIR sensors are used to detect changes in human temperature and environment temperature, but have a high miss rate in the case of...
The objective of this paper is to research to use a few MEMS (Micro Electron Mechanical System) temperature sensors for measurement and estimation of temperature distribution in the core and cavity of the mold during injection molding process. Decreasing the number of MEMS temperature sensors inside the core and cavity will reduce the cost for making product and still calibrate precisely. In this...
