Nice video! Clear and concise but still just enough detail. 🙂 Not using a micro controller was a slick approach as you can demonstrate the output without getting bogged down in a bunch of code. I liked and subscribed. Keep rockin' the great content! 🙂
I used this model to measure my backup water supply tank with an ESP8266. I’m not a fourth aficionado but I still find great practical content on your channel so I just want to communicate my thanks. There seems to be a few different copies of the sensor.. some with limited setting capabilities.. also the mystery chip had me a bit worried when I received mine.. though I reckon it’s just some type of TTL serial chip so no massive loss there.
You mention that you keep the sensor warm by heating it in an enclosure. Is that a plastic enclosure, and does the enclosure affect the readings given by the sensor?
The sensor is Piezo based so freezing can cause damage. The sensor was put into a plywood box enclosure pointing down through a hole in the bottom. A light bulb was enough to keep it from exceeding the operating temperature specs. The transducer face is flush with the wooden box so the readings are not corrupted.
Mount the sensor say 8 feet above the ground in an exposed area that will see snow. With no snow, the sensor will read 8 feet. After a snow fall read the sensor value which will be less than 8 feet. Subtract that reading from 8 feet and that will be the snow depth.

Glad it was helpful! Thanks for the visit.
Never thought of measuring the snow depth... Looks like I have a new project in my future... Thanks

Thanks for sharing!
Very interesting Ken. Another great video.
Thanks John
great sensor, i will use it to measure the level in my pond, thank's.
Great idea! Thanks for the visit.

Was the box held at snow level and the target was the roof ? I am a little confused on how it measured the snow depth.

@@0033mer Thank you
i used this sensor. i have run into problem after cross 200 cm .... it goes wrong somehow or inconsistent
Whats the pot in the upper left corner for?
It's an inductor, not a pot.
i just got mine and did short r19 ... tried to plug it but no led comes on... is it cause of the mode or is it faulty cause i cant make it work too
To put the board into Mode3 a 120K Ohm resistor is applied across the R19 solder pads as shown in the video.
below 20 cm how to measure

so many sensors, so little time ...
