Hi
I am working with HCSR04 ultrasonic range finders. Mbed has a library written for it and i can easily get Distance of an object using these modules. Now can anyone help is there a way i can differentiate between humans and other objects using these sensors.
Actually i want to use these sensors for occupancy detection but the behavior of sensor is not very accurate as the wave can bounce of any object and ultimately i have a variation in distances received.
Has anyone worked in this domain ?
Thank you
