#107679 - Infrared is invisible to the human eye Responding to: ???'s previous message |
Santosh,
The fact that the led is infrared it will never glow. Only an IR(Infrared) detector can detect IR signals. You are right "normal" human beings cannot see infrared with the naked eye.:) Just a suggestion why don't you go for Ultrasound instead of IR for obstacle avoidance. Regards, Ashwin. |
