Ultrasonic Range Finder - LV-MaxSonar-EZ4

The serial interface is a bit odd (it’s RS232 instead of standard TTL), but the PWM and Analog interfaces will allow any micro to listen easily enough. 

Ultrasonic Range Finder - LV-MaxSonar-EZ1

The serial interface is a bit odd (it’s RS232 instead of standard TTL), but the PWM and Analog interfaces will allow any micro to listen easily enough. The sensor provides very accurate readings of 0 to 255 inches (0 to 6.45m) in 1 inch increments with little or no dead zone!
