Avoid
IR-reflection sensor, useful for obstacle avoidance applications. When an obstacle is in front of the IR sender/receiver the ‘Out’ pin is switched low (active low). The circuit sensitivity can be adjusted with a pot. The obstacle detection distance can be adjusted up to approximately 7cm. An enable (EN) jumper can be fitted for continuous operation. Removal of the EN jumper allows an external logic signal (at the EN pin) to switch the detector on and off (low = active, high = off).
