Lower left: diode's cathode
For sensor temperature :-40 to 125 °C
This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC
By measuring the frequency
Infrared Object Detection Sensor ph sensor Lower left: diode's cathodeIntroduction: This Infrared obstacle object detection sensor is super easy to use. It comes with on board potentiometer to adjust the sensitivity. The output is digital signal so it is easy to interface with any microcontroller such as Arduino Uno,Mega, Leonardo, Zero, 101, even the Raspberry Pi or Raspberry Pi Zero. And of course it is also compatible with all other controller boards . This Infrared sensor offers simple, user and fast obstacle
