Features
The Finger Pulse Sensor uses a piezo-electric element to convert force applied to the active surface of the transducer into an electrical analog signal. They are ideal for use in the classroom to study heart rate.
The Finger Pulse Sensor can be used in Lt, with labs in our Lt Sensor Human Physiology Collection. It plugs straight into a Windows-based laptop or desktop computer via USB connection.
Features
- Connects directly to Lt via USB connection with a Windows-based laptop or desktop computer
- The transducer is kept in place using a hook-and-loop fastener around the finger when measuring finger pulse
- Detects expansion and contraction of the finger circumference, due to changes in blood pressure
- Typical output is 100 mV output for finger pulse (ranges from 20 mV to 500 mV depending on person)
