In this video I'm showing how you can send data from an Arduino (NodeMCU) board to a hosted Laravel application. The example is super simple and I use generated random data on the NodeMCU board to ...
In this video, I'm making a carbon monoxide monitor for my home using an MQ7 carbon monoxide sensor, a DHT11 temperature and humidity sensor, and a NodeMCU microcontroller board. This sensor is ...
Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...
Growing neurons rely on chemical cues to find their targets, but new research shows that the brain’s physical properties help shape those signals. Scientists discovered that tissue stiffness can ...
A team of engineers at Rice University has developed a tiny new sensor that could dramatically improve the safety of self-driving cars on public roads. This is a compact, low-power millimeter-wave ...
Researchers in the US have revealed that an emerging class of quantum sensors, called ...
Botanical sensors are turning greenery into living data networks while monitoring plant health and optimizing yields.
