I have several ultrasonic measuring systems I would like to sell. They
measure from 2 to 30 feet, tenths of feet resolution. They would be a
great source for parts for an ultrasonic project, or can be used, as is,
for ultrasonic measuring. I have several that come with the housings but
most are just the electronic guts. The following will be include:
1.) Poloroid ultrasonic sensor and data
2.) ultrasonic driver circuit
3.) 2 lithium batteries
4.) piezo buzzer
5.) LCD display
6.) schematics and circuit explanation
price:
without housing $15 plus $3 shipping
with housing $18 plus $3 shipping
Will sell first come first served determined by email date.
