You can use an ADT7461 single-channel temperature monitor; an ADG708 low-voltage, low-leakage CMOS 8-to-1 multiplexer; and three standard 2N3906 p-n-p transistors to measure the temperature of three separate remote thermal zones (Figure 1). ...

Most handheld devices use alkaline or rechargeable batteries, and measuring the battery capacity is a crucial feature of such designs. Most of the time, however, using a battery level monitoring IC may be a luxury for budget-tight projects. Here is ...

For transducers, such as strain gauges or thermistors, you must accurately and inexpensively measure resistance using circuitry built with imperfect components and in which gain and offset errors can significantly limit the accuracy of ohmic ...

Using measurements of anomalies in the Earth’s magnetic field and machine learning to extract data from raw signals, then matching them to accurate magnetic-anomaly maps, it may possible to navigate aircraft with reasonable accuracy ...

Decibels are commonly used in electronic systems that include RF, audio, and more recently, signal integrity. While many engineers already think in decibels, if you mostly work in the time domain, you may not think the same way. Because much of my ...

Condition monitoring is one of today’s core challenges in the use of mechanical facilities and technical systems in which, for example, motors, generators, and gears are used. Planned maintenance is becoming more and more important for ...

Abstract Measuring the signals from extremely high impedance sensors is a difficult task. These sensors can have output impedances in the Teraohms (1×10 12 Ω). The tiny signal currents coming from sensors such as Faraday cups and ...

Richtek Technology With huge choice of LED lamps available nowadays, it is not always easy to select the best suitable lamp for your living room or workspace. The light quality of LED lamps can vary greatly depending on the lamp design topology and ...

Thomas Brand Analog Devices For a wide variety of products, manufacturing processes require highly precise and reliable temperature measurement technologies. Temperature is often measured through direct contact with a sensor, for example, through ...

Bill Schweber EDN Where there is power there is heat, and where there is heat there is often a need to sense temperature (the most widely sensed physical variable). What we call temperature is our measurement of a material’s thermal energy, ...
