Piezoelectric pulse sensor
This page is in processing now.
It is a long life piezoelectric pulse sensor with signal filtering, conditioning and temperature compensation circuit. The high integration makes it very stable, reliable and extremely easy to use. It outputs the pulse wave which is voltage analog signal. It could be used in pulse wave analysis system, and even the Arduino based system.
- Output analog voltage signal
- High sensitivity
- Anti-jamming design
- Wide overload range
- Better consistency
- Stable and reliable performance
It can be used in pulse wave analysis systems (herbalist doctor pulse manifestation testing, non-invasive cardiovascular function testing system, pregnancy-induced hypertension syndrome testing system, etc). You can integrated it into the Arduino based system.
The warnings and wrong operations possible cause dangerous.
It is the schematic, the circuit about Eagle resource like .pdf should linked here in order to avoid memory exhausted.
