This ultrasonic range finder (MB1010) from Maxbotix is a great choice for use where sensitivity is needed along with side object rejection.
The original LV‑MaxSonar‑EZ products were the first low cost, high quality ultrasonic distance sensors to offer easy to use outputs, no sensor dead zone, calibrated beam patterns, stable range readings, low power demands, and a host of other features.
The LV‑MaxSonar‑EZ1 is our most popular indoor ultrasonic sensor and is a good, low-cost starting place for a customer not sure of which LV‑MaxSonar‑EZ sensor to use.
The serial interface is a bit odd (it's RS232 instead of 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!
Maxbotix is offering the EZ0, EZ1, EZ2, EZ3, and EZ4 with progressively narrower beam angles allowing the sensor to match the application. Please see beam width characteristics explanation below under datasheet LV-EZ1.
