What is measuring angle for SEN-28798?

Sensors Distance
1

The product title of SEN-28798:

Ultrasonic Distance Sensor - 3.3V (HC-SR04), 180° (red)

The 180 degree suggests a wide measuring angle to me. The product details later say:

Measuring Angle: 15°

The datasheet on the product page says 15 deg. and has no mention of any 180 deg.

What’s the measuring angle for this product? If 15 deg., what’s the 180 deg. in the title of the part refer to?

Also, if it’s 15 deg., are the only differences between SEN-28798 and SEN-15569 that SEN-28798 is red and costs more?

The “180” in the product title is almost certainly a typo. According to the manufacturer’s (not Sparkfun) product data sheet the sensing cone is 15 degrees .

The 180 is a typo like mentioned above, we’ll get it corrected

15 degrees is correct :smiley:

The major difference between the 2 versions is higher-quality design/components on the red/SF unit
