From my understanding of ELM97xxxxA series, there is a various range. As for the 4.5V detection IC, it should be ELM9748CAA. Just that how am i going to connect this to make it work?

hello everyone, Currently I am looking for a IC chip which enable me to monitor the voltage of a battery of 9V, when the voltage of the battery falls below 4.8V ~ 4.9V it will trigger and activate a either a buzzer or vibrator. After some goggle on the net I came across ELM9748CAA - CMOS...

Currently I am doing a project on sensor, below is the schematic diagram. From my reading from Fout using the oscilloscope, the nearer an objects/obstacles the frequency increase and vise versa. May I know what I should do/use to convert the high frequency to low frequency and vise versa. or...
