l Effective linear detection distance：6m

l Detection angle (3dB): horizontal ±41°, vertical ±38°

l Not affected by temperature, humidity, airflow, dust, noise, brightness, etc., strong anti-interference ability

l Can transfer through acrylic, glass, plastic and other thin non-metallic materials

 

Sensor debugging

 

l Sensitivity debugging

 

 

Sensitivity debugging can be realized by changing the magnification of the comparator, the default is (1M/20K)*(1M/10K)=5000 times. Can be changed by R11Or R6 resistance value to adjust the test sensitivity, the larger the multiple, the more sensitive. It is recommended that users do not adjust the sensitivity higher than 5000 times.
