Features:
The JSN-SR0T4-2.0 ultrasonic ranging 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 modest on the market.
Some MCUs work.
1, small size, easy to use
2, wide power supply range, low power consumption
3, high measurement accuracy, high resolution
4, the detection blind zone is small, the distance is farther
