As discussed in the first part of the article, the accuracy with which sensor capacitance can be measured using absolute capacitance measurement has a significant dependency on the accuracy of the ...

If you want to measure humidity (and temperature, and maybe even barometric pressure) in a device that you’re building, have a look at this comprehensive test of seven different options. We’re going ...

The BME280 sensor was easier to set up, as it communicates over the I2C serial protocol. This means that we only needed to ...

(Nanowerk Spotlight) Each exhaled breath carries distinct signatures of human activity - quick and shallow during exercise, deep and regular in sleep, irregular while speaking. These breathing ...

Some sensors output a processed analog signal that is linear with respect to the physical quantity being measured. Some perform quantization as well and provide a digital output. Though it is easy to ...
