|uSwitch RX - Hydroacoustic RC system (RX module)
The module is made in the form of a printed circuit board, to which a hydroacoustic receiving antenna (hydrophone) is connected. The device is designed to receive hydroacoustic (ultrasonic) signals generated by the uSwitch TX module.
The TX and RX modules are specially designed by us for the DIY community, enthusiasts, underwater RC model makers as an affordable underwater telecontrol system.
Working with the device is as simple as possible: when the control signal is received via the hydroacoustic channel, digital levels are formed at the outputs, signalling the user about the fact of receiving the signal and the received code (three digital outputs form 8 variants of the received codes).

1 A parameter that determines the maximum range at which a signal can be received, based on the electro-acoustic parameters of the transmitter and receiver, the spatial decrease in the intensity of sound energy, attenuation in the medium and the level of hydroacoustic noise.
2 The maximum communication range is achieved when the transmitter module is supplied with the maximum voltage allowed for it.
3 The specified voltage limits, functionality and serviceability of the module is not guaranteed beyond the specified range.
4 The module uses narrowband tones located in the specified frequency range.
5 The transmitter module is optimized for working with RT-1.332820-1 antenna and the maximum range was determined experimentally with this antenna, when working with other piezoceramic antennas the range can differ significantly.
