Hi, I am looking for a sensor that - can detect one foot-digital sensor -ultrasonic -5V -output should be TTL which is high or low (digital)Also the preset to detect 1 foot and output a high or low when it sees an object. A really important note to add is that it needs to not take too long to detect that an object is there, I had this other sensor that I bought and it takes about 2.5 seconds before going high. That’s too long for it to wait to see if something is there. Also the detect beam should be wide as well, that’s why I’m looking at ultrasonics vs ir. Thank you so much for your time!!
Hi,
Please take a look at our Ultrasonic Range Finders section. The Parallax PING Ultrasonic Sensor might interest you.
