Feature

●Ranging Board This measuring board has an effective measuring distance of 3 cm to 400 cm to simplify the distance.
●Control chip: On board the STM8S 103 high-performance microprocessor whose program burns down.
●High Accuracy The maximum error of ultrasonic measurement is about 1%, very easy and efficient to measure.
●Wide utility: can be used to measure distance and test the performance of the HC‑SR04 ultrasonic module.
●EASY TO USE Equipped with a serial output and digital display tube, the operation is very convenient.

Note:

1. When measuring distance, the area of the object to be measured should not be less than 0.5 square metres and be as flat as possible and have good reflectivity, otherwise it will affect the test results.

2. The effective measuring distance is 3 cm to 400 cm. Exceeding this range may result in inaccurate data or 000 display.
