The Pulse Sensor Kit includes:
Our original kit includes everything you need for a smooth development experience. When your time is money, accept no alternatives.
Easy Earclip
A custom jewelry ear clip, perfectly sized to fit the sensor, ensuring comfortable long-term use. The hands-free design also provides steady and reliable readings for the developer.
Comfortable Finger Stabilizer
Good readings need steady, even contact with your skin. The PulseSensor Kit gives you two ways to get there: a soft Velcro strap that wraps around any fingertip, and the included TPU Stabilizer Ring for an even cleaner signal. Comfortable for the wearer, dependable for whoever's reading the data.
Transparent Vinyl Dots, Electronic Insulation
Transparent Vinyl Dots make electrical insulation simple. Keep your sensor clean and electrically insulted between users. Refill product information.
Color Coded Cables
Color-coded cables make it easy to connect to Arduino and other maker platforms. The PulseSensor can be powered by either 3V or 5V, offering versatility across various maker platforms. The cable is 24-inch long and made of 26 gauge braided copper strands, making it soft and easily fold-able.
