How to measure temperature very accurately with an Arduino
https://www.electronics-lab.com/measure-temperature-accurately-arduino/
This project shows how to measure temperature data from a TSYS01 Temperature Sensor board using Arduino: While studying in university we were challenged as part of a course work into designing a box with very accurate temperature control. If the project were to succeed, multiple boxes were to be built and used in a research […]
Analogue Sensors – Calculate the Nonlinearity Introduced by a Load or Pull Down Resistor
https://www.electronics-lab.com/analogue-sensors-calculate-nonlinearity-introduced-load-pull-resistor/
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 maximum and minimum locations when using analogue digital convertors (ADCs). I […]

https://www.electronics-lab.com/a-biometric-sensor-for-wearables/
LG Innotek has released an ultra-thin optical biometric sensor module designed to be used in wearables and smartphones to measure health parameters such as heartbeat, stress indicators and blood oxygen saturation level. The new sensor is more accurate than it’s predecessors achieving ±5 bpm range of error and consumes very little power to operate. At stable heartbeat […]
Chemoelectronics: Nanoparticle Diodes and Devices That Work When Wet
https://www.electronics-lab.com/chemoelectronics-nanoparticle-diodes-and-devices-that-work-when-wet/
Dexter Johnson has a writeup about flexible, water-loving logic circuits and sensors without the need of semiconductors. They constructed the chemoelectronic devices by coating gold nanoparticles with any of four types of organic molecules called ligands. Each ligand produces a different, charge-related effect when put in water or a humid environment. One dissolved, releasing a postive […]
SDP3x – world’s smallest differential pressure sensor
https://www.electronics-lab.com/sdp3x-worlds-smallest-differential-pressure-sensor/
The SDP3x is the world’s smallest differential pressure sensor. It measures just 5 mm x 8 mm x 5 mm, enabling it to be integrated in a range of portable devices. Measurement range is ±500Pa (±2 in. H2O) and has excellent accuracy and repeatability even below 1Pa. It is calibrated and temperature compensated on the […]
