This page is a placeholder about __[ultrasonic sensors]__.



Most hobbyist robots use a commonly-available ultrasonics module (typically called an HC-SR04 or something similar) that costs a few dollars. 

I've been using a driver board from PiBorg called the [UltraBorg|https://www.piborg.org/sensors-1136/ultraborg] that has both support for four servos and four HC-SR04 ultrasonic sensors, with a support library in Python.


!! SensComp Ultrasonics

A more advanced sensor is available from [SensComp|http://www.senscomp.com/], which uses a transducer similar to those found in the Polaroid SX-70 Sonar camera, circa 1978. These sensors are have a longer range and are more sensitive than their cheaper brethren. 
 
I contacted SensComp and received more information about their sensors. See the documents attached to this page.

SensComp offers a complete Development kit using the Arduino. This is the __Smart Sensor Ultrasonic Development Kit For Arduino__, [attached is a spec sheet|UltrasonicSensor/Smart_Sensor_Ultrasonic_Development_Kit_for_Arduino_Spec-201303-08.pdf] for the kit. I have also included the [spec sheet for the Smart sensor|UltrasonicSensor/Smart_Sensor_Spec_2013-03-08.pdf] itself which can also be purchased separately. Also [attached is the code|attach/UltrasonicSensor/Ping_SMRT.ino] for the development kit.

According to SensComp there is currently no known Python/MicroPython port of the Arduino C code.
