Product Details
The MAX25205 evaluation kit (EV kit) is a complete system for demonstrating the MAX25205 optical IR sensor in a typical gesture and proximity-sensing application.
The MAX25205 enables recognition of the following gestures:
- Hand Swipe Left, Right, Up, and Down
- Finger/Hand Rotation Clockwise and Counterclockwise
- Air Click
- Proximity Detection and Linger-to-Click
The application circuit operates by illuminating the user’s hand with a precision-controlled IR light source and measuring the reflected signal with the MAX25205’s 6x10 (60 pixel) IR sensor array. The four-LED IR light source is PWM controlled with external FETs from the MAX25205’s onboard FET driver. The return signal is analyzed with an embedded microcontroller that interprets the gestures.
The EV Kit consists of the following:
- MAX32620FTHR Microcontroller Platform
- Interface Shield Board
- MAX25205 Sensor Board
- Ribbon Cable (Connects Sensor Board to Shield Board)
- 3.3V Power Supply
- USB 2.0 Type A to Micro B Cable
Applications
- Central Information Display Control
- Door, Moon Roof, and Trunk Control
- Mechanical Switch Replacement
- Occupant Detection
- Rear-Seat Entertainment Systems
