Susan Nordyk @ edn.com discuss about LTC2986 which is able to digitize and linearize a combination of temperature sensors in Celsius or Fahrenheit degrees. A 10-channel temperature-measurement IC, the LTC2986 from Linear Technology directly digitizes any combination of thermocouples,...

Tecwyn Twmffat @ instructables.com discuss about the notlinearity introduced by adding a pull down resistor and why you may get unpredictable readings from your ADC. For many years I found that I would get strange, unpredictable, readings from my sensor related projects at the...

This is a simple signal conditioner circuit for Piezoelectric sensors. The circuit converts the input charge to voltage and the level shifts to the ADC input range of 0.1 V to 2.4 V. The circuit is built using AD8608 OPAMP from Analog devices. Piezoelectric elements are used to...

The project presented here is an analog capacitive proximity sensor. The circuit is from Texas Instruments application note. Most conventional capacitive proximity sensors produce a "1" or "0" output, this circuit produces a DC output that is a function of the size and relative...

The project described here is a two-channel ultra-precise, current-sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range from 2.7 V to 120 V. The INA2290A1 chip is the heart of the project. The ultra-precise current measurement accuracy is...

Sensors are everywhere from your smartphone, and smartwatches to everyday applications like refrigerators, cars, and lifts, making everyday life easier. There’s probably not a day that goes by where you aren’t impacted in some way by a sensor. So in this article, we will talk all...
