Pulse Sensor for Automotive Diagnostics (27mm piezo)

thingiverse

I created this so others can build a homemade pulse sensor. The commercial version is called the "First Look" sensor. I attribute the original homemade design to Youtuber Forklift Geek, who inspired many others to make their own pulse sensors using plumbing fittings. I was going to do just that but I had trouble sourcing the correct size piezo, so I used a pack of 27 mm piezos and made my own housing. I took it further by designing the barb fittings since the brass ones cost ~$4 each. This design is threaded for ¼” mip, allowing you to use them if you prefer. I think this design turned out nicely. I hope it will help and inspire people to take an interest in advanced vehicle diagnostics. This design is not intended for mass production or sale for monetary gain. If you're looking for a ready-to-use kit, be sure to pick one up from Cody's Auto Diagnostics.
