ME007YS Ultrasonic sensor outputs 0 as distance

The sensor may be trying to measure an object that is too close or too far away to be detected. Since the ME007YS has a detection range of 28 cm to 450 cm, if the object is closer than 28 cm, it could result in a 0 distance reading. Please place the object within the detection range of the sensor.

The ultrasonic sensor ME007YS returning a value of "0" (with raw data 0xff 0x00 0x00 0xff) typically indicates that the sensor is either not detecting a valid distance or is encountering an issue. This could happen if the object is outside the sensor's detection range, either closer than 28 cm or farther than 450 cm. Additionally, the sensor may return "0" if it doesn’t detect any object within its range. Environmental factors like temperature, humidity, or reflective surfaces can also interfere with the sensor’s readings, causing it to output "0" even if the checksum is valid.
