Where can i buy nu25c16t? I rummaged through the entire Internet, I can not find anywhere. Where did you buy them?

fritztoch commented 4 years ago

I believe there is an equivalent part TCRT16-40 which is available on AliExpress and Amazon.

vovo255 commented 4 years ago

But is it 40 kHz? This transmitter will suit you? You have 25 kHz.

SCWhite commented 4 years ago

@vovo255 HI, I can confirm that 40kHz works jamming the mic (not sure the performance compare with 25kHz). but you may need to change the code and some component. may be try TCT25-16 ?

You find them on eBay https://www.ebay.com/itm/16MM-Ultrasonic-Sensor-Probe-Transceiver-Receiver-TCT40-16T-R-NU25C16T-1-/272708217220

@SCWhite I'm planning on recreate the device with a 40Khz transmitter. Which are those changes on the code that you mention to confirm that it worked with this frequencies.

T-vK commented 4 years ago

That ebay offer is extremely expensive and includes the R-variant which is basically a microphone rather than a speaker. You'd pay like $63 for 23 of those. You find much better offers on aliexpress. See #6

transmitter, receiver or transceiver 25Khz?

SCWhite commented 1 year ago

in this case, you will just be using "transmit" so transmitter and transceiver should both work.

And where can I buy nu25c16t ?
