This is the basic Pulse Sensor Hot Glue Seal, It’s also got the clear vinyl sticker on the front face. We’re calling
this ‘Water Resistant’, ready to be handled and passed around from fingers to earlobes or whatever. It is not
advised to submerge or soak the Pulse Sensor with this basic seal.
Now you can stick on the velcro dot (included) and make a finger strap with the velcro tape (included)
