The 40kHz Ultrasonic Transducer Receiver DIY Kit
This listing is for an ultrasonic air transducer receiver DIY electronics kit. The above video gives you a demonstration of the functionality of the device. When powered, the device acts to amplify ultrasonic signals that are within close proximity of the device. There are three pre-amplifier stages on this receiver board. When a signal hits the on-board 40kHz ultrasonic receiver transducer, it is amplified, and sent through an LM386 comparator circuit. If the incoming signal is strong enough, the kit will output a square wave signal that is outputted from the comparator to the output pin. The default configuration of the kit will receive signals properly from a our ultrasonic transmitter kit from about 1.5 to 2 meters away. However, there is a simple modification that will allow for you to receive signals from upwards of 10 meters away. There is a modification video below.
There are three pins (They are labelled on the board):
1 - DC Ground
2 - Output
3 - V+ (While the board says 5-9v, unless you bypass the on board 78L05 5v regulator, you will need between 7-10v for proper operation.
Ultrasonic signals do not pass easily though walls. However, they do bounce off walls and other solid objects. Above is the assembly video, and some transmitter/receiver documents that I created long ago that you can use for reference. We also sell an ultrasonic transmitter DIY electronics kit that works well with this kit, so check out our store!
THIS KIT COMES WITH:
1x custom PCB (Printed Circuit Board)
1x 3-pin header
1x LM386 Amplifier IC
1x 8-pin DIP socket1x 78L)% 5v regulator
3x 2N2222 NPN transistors
4x 0.1uf ceramic capacitors
3x 10uf electrolytic capacitors
1x Ultrasonic 40kHx receiver transducer
4x 180k resistors
4x 15k resistors
3x 330k resistors
2x 18k resistors
1x 5.6k resistor
1x 68k resistor
NOTE: Please note that the instructions are in the above assembly video, and that no hard copy will be included. Just the components.
REQUIREMENTS:
1) A 7v to 10v power supply
2) Attention to detail
3) Soldering experience is helpful

This document was created a long time ago for a kit that we no longer sell. The transmitter and receiver circuits can be used for any 40kHz standard transducers. This transmitter kit is based on this document.
