2-in-1 Line Tracking Sensor + Flame Detection Sensor Modules Set - Black + Red
Used for intelligent cars or robots to track lines (black and white lines); - With this sensor£¬ the intelligent cars can avoid to fall off the cliff and avoid obstacles (Note: Due to short effective detection range£¬ the objects close to black color can not be detected.); - Supports reflective materials detection£¬ such as papers£¬ cassettes£¬ non-contact IC cards£¬ etc; - Detection distance: white paper: about 2cm; Different colors£¬ different detection distance; The detection distance of white color is the longest; - Power supply: 2.5~12V£¬ do not exceed 12V (Note: Suggest to use low-voltage power supply£¬ since the sensor life will be shortened if use high-voltage power supply; 5V is the best.); - Working current: 18~20mA (when the voltage is 5V); The sensor performance is the best when the working current is 18~20mA£¬ mainly in the anti-interference aspect; - The sensor will output low-level signal when detects objects£¬ output high-level signal when detects nothing; - Outputs TTL level to connect to the IO interface of 3.3V or 5V single chip microcomputers.
