PS-3236 wireless ECG sensor
The PS-3236 wireless EKG sensor measures electrical signals generated by heart or muscle contractions and displays live data on almost any student device. It gives students real-time feedback while investigating the effects of different stimuli on cardiac or muscle activity. It also studies nerve impulses affecting muscles other than the heart, supporting exploration of reflexes, muscle fatigue, and other physiology. Overview: Ideal for fast-paced physiology courses, the sensor provides live feedback as students investigate how stimuli affect cardiac or muscle activity. Heart rate is shown in beats per minute (BPM), while voltage detected during heart contraction, in mV, appears as an intuitive EKG trace. This product is not a medical device. PASCO products are designed solely for education and must not be used in life-support equipment, medical testing, patient diagnosis, industrial control/testing systems, or related apparatus. With each heartbeat, the heart's pacemaker, the sinoatrial node (SA node), conducts an electrical signal. It travels downward from the SA node in the upper right chamber to the lower chambers, the ventricles. Electrical activity always precedes muscle contraction, and electrodes attached at various body locations record the heart's electrical signal. An electrocardiogram, abbreviated EKG or ECG, records these signals and can be used to assess whether heart rhythm and electrical conduction are normal. Other muscles also contract in response to electrical signals. The EKG sensor can reveal timing relationships between stimuli and reflexes, such as signal changes when the Achilles or patellar tendon is tapped to elicit a reflex, including the knee-jerk response.

PS-2011 dual-channel Bluetooth interface
Sensors
Brolight
Interface Type: USB or Bluetooth 2.0 Interface: 4 (2 PASPORT interfaces, 1 voltage interface, 1 temperature interface)
The PS-2011 SPARKlink dual-channel Bluetooth interface lets teachers and students connect their devices by USB or Bluetooth to any of more than 70 PASPORT sensors in the PASCO range. Data are acquired with SPARKvue or PASCO Capstone. Teachers and students can use desktop or laptop computers running either program, or Bluetooth-enabled iOS or Android devices running the SPARKvue app. Note: SPARKlink Air connects to Google Chromebooks by USB but does not support Bluetooth connection to them.

Fully integrated 4-channel DVS optical module
Sensors
Oe-photonics
Sensing distance: typical:20 km Number of detection channels: 4 channels Modulation mode: External modulation
For multichannel, fully integrated distributed vibration sensing (DVS), the DVS-AOM-L series uses an ultra-narrow-linewidth laser with optimized optomechanical/electrical integration. Serial-port parameter configuration, high integration, environmental-interference resistance, compact size, and convenience are provided. Sharing a narrow-linewidth laser reduces multichannel costs, particularly for demanding sensing applications. Custom solutions and specifications are available to sensor-equipment manufacturers.
