This module consists of two inters, namely the mode selection and jumper5 PinInter.

Number from left to right1,2,3,4,5. Their definitions are as follows:
In the module of power before, first remove the jumper jumper on mode selection, the module is in level triggered mode.
The timing of level triggered ranging is shown in Fig.Five point oneAs shown:

When the echo signal is detected, the module also carries out the measurement of the temperature value, and then, according to the current temperature, the measuring result is corrected.Echo/RXPin output.
In this mode, the distance values are transformed into340m/sTime value of2Times byEchoOutput a high level, which can be calculated based on the duration of the high value of the distance. Namely the distance value is:(High level time*340m/s) /2.
Note: because the distance value has been adjusted by temperature, no need to correct the velocity of sound by the ambient temperature at this time, that is, no matter how much the temperature is, the speed of sound is chosen.340m/sCan.
In the module of power before the first plug jumper cap on the jumper mode selection, module in serial trigger mode.
