Both negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistors’ values change as a result of temperature but impact their use differently. For NTC thermistors, as temperature increases, the resistance drops from high to low and allows current to pass through. In a circuit, they can limit in-rush current by self-heating when current is […]
Frequently Asked Question (FAQ)
How to design an effective telehealth system
By Marcel Consée, Mouser Electronics Healthcare can be deeply personal, and direct contact between patients and medical personnel remains vital. However, taking the relationship between doctors and nurses out of the equation can sometimes make sense. Medical crises such as the global COVID-19 pandemic accelerate the adoption of telehealth methods, even though the original idea […]
The role of ADAS sensors in automotive design
Advanced Driver Assistance Systems (ADAS) are intended to prevent deaths and injuries by reducing accidents. Exemplary ADAS applications include: pedestrian detection/avoidance, lane departure warning/correction; traffic sign recognition; automatic emergency braking, and; blind-spot detection. This FAQ starts with an overview of the “levels of driving automation” and its relation to ADAS. It then reviews the role […]
How can thousands of wireless sensors be deployed without requiring battery maintenance?
Wireless applications that need continuous monitoring to save energy, detect unsafe or other avoidable conditions and need to avoid creating serious maintenance issues are prime candidates for energy harvesting. Steam trap monitoring provides an excellent example of this type of batteryless sensing. Roughly 20% of the steam leaving a typical facility’s central boiler plant in space […]
Can the AgeMeter help you?
Developed by Centers for Age Control, the AgeMeter takes user data and physiological biomarker tests to calculate functional age and provide other age-related feedback to users. Since it tests physiological biomarkers that decline with age, the AgeMeter can validate aging reversal as well as anti-aging therapies for healthcare practices, researchers, fitness programs and consumers. Intended […]
An introduction to ultrasonic sensors
Ultrasonic sensors have been a popular method for distance measurement and object detection for many years. Their basic operating principle works by measuring the amount of time it takes for their emitted ultrasonic pulse of sound to bounce off an object and return, hence the name ultrasonic sensor. With the market for autonomous robots, vehicles, […]
How do materials impact a sensor’s performance? Pt 2
The right materials are essential to achieve the desired sensor electrical performance, especially in many more demanding, high performance applications. Part 1 showed the performance impact of different sensor materials on infrared (IR) optical sensors. Radio frequency (RF) sensors also provide some interesting examples of a material’s impact on sensor performance. With expanding RF applications […]
How can force sensing be integrated for Industry 4.0 upgrades?
Upgrading facilities to Industry 4.0 standards is one of the most significant trends in the manufacturing industry today. To do this, original equipment manufacturers (OEMs) are pushing hard to renovate their facilities with connected, automated devices and machines to create greater efficiency and cost savings. Smarter devices can ease the transition. For example, force measurement […]
The challenge of temperature measurement and sensor calibration, Part 3
Temperature is a widely measured real-world physical variable, but achieving credible results is harder than it seems, even for a simple device such as a kitchen oven. While many temperature-related measurements require high accuracy, precision, and repeatability — let’s say, to better than 1º C — many others do not, yet still bring challenges. Consider […]
The challenge of temperature measurement and sensor calibration: part 2
Temperature is a widely measured real-world physical variable, but achieving credible results is harder than it seems, even for a simple device such as a kitchen oven. What is temperature, anyway? While we all “know” intuitively what temperature is, actually defining and calibrating its readings is a complicated discussion. A fundamentalist approach is to go […]
