- This module has stable performance and accurate measurement distance. The module has high precision, blind area (25cm) and stable ranging are the strong basis for this product to successfully enter the market.
- Use the I/O port TRIG to trigger ranging and give high-level signals of at least 10us. The module automatically sends 8 40khz square waves to automatically detect whether signals are returned. When a signal is returned, echo outputs a high level through the IO port, the duration of the high level is the time from the transmission to the return of the ultrasonic wave.Such continuous periodic measurement can reach the value of your mobile measurement.
- Test Distance = (High Level Time * Sound Speed (340m/s))/2.

i connected it to my NODEMCU V3, which powers it 5V, however, in my project, it does not work smoothly, it some times provide measurement, most of the time not. Overall quliatywize its seems good but operationally no.
