Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “DIY RTD for a DMM.”With a fortnight’s struggle, I completed the design of 4 mA to 20mA, ...

The two lines are plotted in Figure 2, which shows that the temperature of intersection (T INT) is 58.55°C.Since the LM19 and LM61 essentially do not sink current (less than 10 µA), V OUT will ...

For PNP transistor E will be positive terminal and B-C will be negative. Hence by shorting the B and C, we can use transistor as Temperature Detector. Below is the NPN transistor BC547 Pin ...

The project aims to build a digital sensor thermometer based on TMP275which is 0.5°C accurate and uses 2-wire interface to connect to a microcontroller. The TMP275 is a serial output temperature ...

Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.

There is a lot going on inside Allegro’s latest two-terminal Hall-effect detector. Not only is there DSP alongside the chip’s sensors, but a co-packaged supply capacitor too. Aimed at sensing ...

Abstract: This paper presents readout and control circuit for plurality of ion sensitive field effect transistor (ISFET) sensors interfaced with ADG715 octal switch which is controlled by ...

This study presents a silicon-based pressure sensor with temperature compensation. The eight piezoresistors were designed on the polycrystalline silicon membrane and constructed by two concentric ...

This article presents a new self-powered temperature sensor based on thermoelectric generators (TEGs). Two different types of TEGs measure temperature and supply the interface circuit. The interface ...
