A look at how R&D engineers can validate an electrostatic ultrasonic concept on an Arduino® — and carry that work toward a production design without starting the sensing layer over from scratch. Most ultrasonic prototypes start the same way: an engineer grabs whatever $3 ultrasonic module is in the parts drawer, wires it to an […]

At SensComp, Inc., we are proud to offer a scholarship program for students in the process of pursuing a college degree in a STEM field. The awarded student will receive $1,000 to be used towards tuition for his or her degree. Who may apply? A U.S. citizen accepted to or currently attending a college or

How electrostatic ultrasonic sensing gives automated side loaders — and operator-assisted rear and front loaders — reliable distance data to support cleaner grabs, fewer collisions, and better-informed control and safety logic. A modern residential collection route is one of the most demanding sensing environments in the heavy-equipment world. An automated side loader (ASL) pulls up

Level sensing sounds straightforward until you look at what’s actually inside the tank. A flat water surface and a cone of granular powder don’t behave the same way acoustically — not even close. Engineers designing level measurement systems need to account for both ends of that spectrum, and often everything in between, within a single

Self-service health screening kiosks are showing up in pharmacies, employer wellness centers, urgent care lobbies, and telehealth stations. They measure blood pressure, weight, BMI, temperature, and other vitals without requiring a staff member to operate them. The concept works — until the kiosk can’t tell whether someone is actually standing in front of it. Patient

Using ultrasonic sensors in noisy environments can cause the sensor to detect false ultrasonic signals created by whistles, brakes, animals, machinery and other sources.  One method to minimize this problem is to use a multifrequency ultrasonic transmission chirp.  SensComp’s 600 series electrostatic transducers can be used for this application.  Unlike piezo transducers that operate at

The Challenge: Why Standard Piezoelectric Sensors Fail Modern AGVs Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs) are the backbone of modern material handling. Yet the efficiency of an AGV is limited by its ability to perceive its environment. If an AGV can’t reliably detect a forklift tine at 15 feet or a warehouse

What Is Ultrasonic Snow Depth Measurement? Electrostatic ultrasonic sensors measure snow height by emitting a 40 kHz acoustic pulse downward toward the ground, detecting the return echo from the air–snow interface, and converting the round-trip travel time into a distance measurement. Snow depth is then calculated by subtracting that measured distance from the known reference

Electrostatic ultrasonic sensors and transducers deliver performance advantages that piezoelectric sensors cannot match—particularly in applications that require long range, soft-target detection, small-object recognition, or stable operation across temperature changes. By leveraging a lightweight electrostatic membrane rather than a heavy ceramic disk, these sensors achieve up to 40 dB higher sensitivity, and maintain consistent performance in conditions

When most engineers think about in-air ultrasonic sensing, they picture a cheap, ceramic “hockey puck” — a piezoelectric transducer. But piezo is not the only option, and not always the right choice. Electrostatic ultrasonic sensors use a different transduction mechanism that delivers higher sensitivity, wider bandwidth, and more stable performance in demanding in-air applications. How
