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...

Microchip Technology has released a new family of Digital Signal Controllers (DSCs) called dsPIC33A. These controllers are designed for time-constrained systems that need fast and precise control. The DSCs are built with a 32-bit architecture with a double-precision floating-point unit...

Arduino has announced two new entries in its Opta programmable logic controller (PLC) family, designed for those projects that are a little too complex for a single controller: the Opta Digital and Opta Analog Expansion Modules. These new modules offer additional pins and true analog...

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...
