Photoelectric sensor selection: target and background matter. Wrong selection can cause false detection, missed objects, and unstable PLC inputs. https://zurl.co/CdDpc Article: https://zurl.co/kT6Wq #PhotoelectricSensor #Sensors #IndustrialAutomation #SensorSelection

💁🏻‍♀️ TIL: Engineers at #PennState have developed a conductive #ink that works like face paint to create customizable electrodes for monitoring #heart, #muscle, and #brain activity. The #water-based ink dries on #skin within minutes, conforms closely for more accurate readings, and can be washed off and reapplied. In tests, the sensors tracked #ECG for 12 hours and fed muscle signals to a robotic #prosthetic. 👉 https://www.popsci.com/technology/colorful-paint-on-health-sensors/ #sensors #health #wearables #stem #ecg #emg #science #invention #engineering #biotech #tech #technology

Straight out of my ZHAW School of Management and Law and Geneva Graduate Institute summer school lectures on #AI and #SecurityPolicy : as #sensors become ubiquitous and processing the gathered data increasingly relies on machines, expect more and more countertactics to be focused on fooling machines, not humans "In recent months Russian military lorries in Ukraine have begun sporting a striking new colour scheme of vivid black-and-white stripes. As camouflage goes, it is not much use against human observers. But then, it is not intended to fool biological eyes. Its aim is to frustrate the machine-vision systems that are fitted to the Ukrainian drones that zip around battlefields looking for prey." https://www.economist.com/science-and-technology/2026/07/08/how-to-hide-from-killer-drones

Sensor signal unstable? Check the basics before replacing the sensor. Vibration, wrong mounting, reflective targets, cable noise, weak 24V supply, or wrong output type can cause false signals and PLC input flicker. Share sensor model + application photo with SmidMart for faster support. https://zurl.co/xR7dG #Sensors #PLC #AutomationTroubleshooting #FactoryAutomation #Smidmart

For those folks looking for programmable #sensors or #controllers or other devices that are easily customized, i recommend Phidgets. A 🇨🇦 company, based in #Calgary, #Alberta, that has been around for about 20 years. I have used it for sensor projects (heat and humidity) and a fun #RFID project. Huge library of projects available in a lot of languages (C, C#, Python, Java, and more). Lots of online support. Most devices are backwards compatible, but their have been new standards (e.g. RFID) which require reader up grades. Well made, inexpenaive. #Computers #IT https://phidgets.com/
