Ultrasonic range finder adapter DIY kit See Assembly Video Within!
This listing is for an ultrasonic transmitter/receiver adapter DIY Electronics Kit. The transmitter is fed a 40kHz square wave pulse via a 555 timer chip set up in astable mode. If an object gets in the way of the transmitted signal, the signal is bounced back and is received by the receiver transducer. The receiver circuitry amplifies the signal sends the return pulse to the RX output pin on the main board, which can be connected to your microprocessor for further pressing. The video above offers a demonstration, while the video BELOW offers step by step assembly instructions so that you may follow along! Please watch the video below in full. There is an on/off button on the main board, and there are four mounting holes; one in each corner. This kit is to be interfaced with your arduino or other microcontroller platform. This kit provides the hardware. You supply the software! We also sell this in assembled form for a few dollars more, so be sure to check out our store!
You can also disengage the 40kHz signal from the 555 timer, and apply your own signal externally if you wish. Do do this, remove the header connector on the 555_EN pins, and apply your own square wave signal via the EXT pin on the 3-pin header. This is only an option that you can use if you wish. The device has a two pin output, which is comprised of a ground connection, and an RX pin, which is the received signal output.
If there is nothing in the field of view (FOV), then the output (RX pin) will sit at 5v. If something is within range (Max is about 2.5m to 3m), then the signal will get bounced back. The returned signal frequency will depend on how far away the object is. The further away, the lower the frequency. The closer the object is, the higher the frequency.
When the object detects nothing in the immediate FOV, the device consumes about 10mA (Idle mode). The amperage goes up if an object is detected. The closer the object, the more the current. Max current is about 30mA.
We will also be selling this in fully assembled and tested form for a few dollars more, so if you are interested, check out our store! We have tons of awesome stuff available!!!
The terminal block on board has two pins: V+ (positive supply voltage - 7-12VDC), and GND (DC ground).
Specifications:
Input Supply Voltage: 7-12VDC
Standby Current: Roughly 10mA
Max Current: Roughly 30mA
Length: 53mm
Width: 40mm
Height: 24mm
