The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Whenever the temperature climbs, we all see social media posts of car dashboards offering blisteringly hot temperature claims, but how accurate are they? As the big question is, really, where is the ...

In this era where supply chains are rapidly evolving, one important sector, cold chain transportation, is undergoing a significant transformation. Critical for transporting perishable goods like fresh ...

Total mastery over the pinout and functionality of the PCA9306 for conversion of logic levels from 5V to 3.3V. A step-by-step interfacing diagram for the PCA9306 to Arduino UNO. Working example with ...

We all love seeing data represented in pretty ways — whether it’s necessary or not. Take VU meters for example. They’re a super useful tool for audio editors to balance signals, but they also look ...

Over the past decades, physicists and quantum engineers introduced a wide range of systems that perform desired functions leveraging quantum mechanical effects. These include so-called quantum sensors ...

A dual resonator graphene sensor measures pressure with exceptional precision and stability, using built-in temperature compensation to maintain accuracy across wide pressure and temperature ranges.

We love Arduino here at Hackaday; they’ve probably done more to make embedded programming accessible to more people than anything else in the history of the field. One thing the Arduino ecosystem is ...

Recently I was looking for an inexpensive pressure + temperature sensor for a barometric altimeter project, which then led to me finding the SPL07-003. After learning there was no existing library to ...

Environmental temperature fluctuations can cause sensor output variations separate from measured pressure. A sensor’s thermal sensitivity dictates the severity of these output errors, with higher ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...
