I highly recommend Maxbotic sonar sensors. Good accuracy and easy to interface.how i connect the PIC 16A84 with the ultrasonic sensor.have any schematics?then how to show how far is the obstacle left on LCD.THX
How about the sensors used on Solarbotic's Sumovore? They're simple, reliable and good for probably 12 inches sensing range or a bit more. You can get the schematic here. Look on Page 29 for the Full Schematic. You're looking for 38khz IR Object Sensors and 38khz IR emitter. Parts list is somewhere earlier in the doc.hey,futz.if i wan build my own the obstacle detector,do you have any idea how to build it.actually my project is remote control car.i using PIC16F84A to control the motor and it also can detect the obstacle. When it detects obstacle, it sends the signal to LCD and then the LCD will show the how far distance from obstacle.
Not really as sonar is usually in the audible range where Ultrasonic is not.Ultrasonic and SONAR are the same thing.
hi,everybody
any body know aboutsonar radar?
Oh, this is an old thread. Guess I should be more attentive.
My Project Is Making Rc Car That Used The Ultrasonic Proximity Sensor To Detect Range Of Object In Front. By The Ranging, It Can Slow The Car When Near To The Object And Move Fast Forward When It Far From The Object In Front. For Info I'm Using Pic16f877a.
Please If U Have Any Ideas. Send Me Schematic Diagram And The Source Code
Thanks...
