Ultrasonic Sensors
Ultrasonic sensors are ideally suited to accurate, automatic distance measurement in normal and difficult environments. Ultrasonic sensors are particularly suitable for environments where optical sensors are unusable such as smoke, dust and similar. Ultrasonic sensors are very accurate, stable and can be used over large ranges. Complete list of PIL Ultrasonic Sensors
