Operating Voltage 6 10 Vdc single source Operating frequency broadband output ranging up to 250k Hz Built-in variable RC oscillator matching transducers with different frequencies High gain amplifier varies with time over 32 steps Integrated Band Pass Filter reduces external component count Bi-direction IO Pin simplifies the control function for transmitting a pulse & receiving an echo An adjustable System Clock enables the control of the number of pulses transmitted the slope of the variable gain amplifier & the pulse repetition rate Board size L x W 27.9 x 18 mm The SRM400 is a sonar ranging module utilising new developed Sonar Ranging IC PW-0268 which can work with all PT or EP type transducers. SRM400 provides as a shortcut to develop car reversing systems or some other distance measurement systems for design engineers who are not very familiar with analogue circuit andor the operation of ultrasonic transducers. By using this module engineers can focus firstly on the other fields of digital circuit & software designs as well asbrsome other mechanical issues. After first stage then you can either design your own analogue circuit based on the module construction or consult with factory for making your own module for your special needs. ...
