Description
This module can provide 20cm-600cm non-contact distance sensing function, and the ranging accuracy can be up to 2mm. The module consists of an integrated ultrasonic sensor and control circuit.
This product adopts industrial grade integrated ultrasonic probe design, waterproof type, stable performance, and can work with all MCU in the market. 1. The performance of this module is stable and the measurement distance is accurate. It can compete with foreign ultrasonic ranging modules such as SRF05 and SRF02. The module has a variety of modes that can be modified manually, suitable for testing and teaching experiments in different occasions. The distance sensor is small in size, convenient to use, stable in performance, and high in measurement accuracy.
This distance measurement has high precision module, blind zone (20cm), stable ranging is a powerful basis.
