I am using an ultrasonic distance sensor to measure range (duh). When I first got the sensor, it seemed to measure up to about 300cm, but recently it is maxing out at about 200 to 150cm. Do these sensors degrade over time? Do I have a bad sensor? I have read other people saying that it is common for these to only reach about 150cm - can anyone who has worked with these give me their experience?
Edit: This range limitation occurs whether I ask for a measurement every second or every 20 milliseconds. It happens indoors and outdoors and different types of indoor rooms
