SRM400

The SRM400 is a sonar ranging module utilizing our new developed Sonar Ranging IC, PW-0268, which can work with all our 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 analog circuit and/or the operation of ultrasonic transducers. By using this module engineers can focus firstly on the other fields of digital circuit and software designs as well as some other mechanical issues. After first stage then you can either design your own analog circuit based on the module construction or consult with factory for making your own
module for your special needs.

Features:

• Operating Voltage: 6-10Vdc single source
• Operating Frequency: broadband output ranging up to 250KHz
• 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 I/O Pin: simplifies the control function for transmitting a pulse and receiving an echo
• An adjustable System Clock: enables the control of, the number of pulses transmitted, the slope of the variable gain amplifier, and the pulse repetition rate
• Board size: 27.9 * 18 mm (L*W)
