NXP’s accelerometer chip MMA8450Q, provides orientation detection on handheld devices: This application note targets the portrait/landscape orientation detection feature which has become standard in many hand-held electronic devices. Additionally, this application note aims to explain uses as well as highlight some of the challenges of designing an embedded algorithm into the sensor. Included in content, […]
iBreathe, A Breathalyzer Based on Hexiwear
https://www.electronics-lab.com/ibreathe-breathalyzer-based-hexiwear/
Knowing the amount of alcohol you drunk is becoming easier using the iBreathe Breathalyzer project by Dave Clarke. You just have to blow in the alcohol sensor, then it pings the result to a smartphone app and to the cloud to document it as a table so you can see alcohol intake through time. This […]
A Multi-Use Mini Sensor Platform
https://www.electronics-lab.com/multi-use-mini-sensor-platform/
While developing a smart hardware project, such as control and automation systems, you will almost need to use different types of sensors for collecting and gathering necessary data. LastSamurai had designed a platform that aims to simplify the use of digital and analogue sensors. The platform was developed based on MySensors Hardware, hardware components that […]
