Fingerprint Sensor JM-101B

The Fingerprint Sensor JM-101B is a compact fingerprint reader module for adding biometric identification to electronics projects. Connected to a microcontroller such as an Arduino or ESP32, it lets your project recognise authorised users by their fingerprint, making it a popular choice for smart door locks, safes, cabinets and attendance systems.

Fingerprint Sensor JM-101B Specifications

What's in the Box

• 1 × JM-101B fingerprint sensor module

Tip: Check the module's pin labels and supply voltage before wiring, since many fingerprint modules run at 3.3 V and can be damaged by 5 V. Keep the sensor window clean and dry, and place the finger flat and centred for the most reliable reads. Store enrolled user IDs in your own code so you can map each fingerprint to a name or action.
