A static electricity protection wrist strap comprises a casing inside which a conductive plate is mounted. The conductive plate has serrated side extensions for engaging a strap extending from one side of the casing, around the wrist of a user and back to connect to the other side of the casing. A grounding wire in electrical connection with the conductive plate provides the static electricity protection wrist strap a grounding connection. A static electricity detection device comprises a detection plate which constitutes a capacitor with the skin of the wrist wearing the wrist strap and a processing unit for detecting the variation of the capacitor. The processing unit comprises a beeper which will be actuated to send out a warning signal when an increase of the static electricity collected on the wrist skin is detected.
