  Liquid Level Sensor‐FS‐IR02 SKU: SEN0205 From Robot Wiki    Contents     1 Introduction  2 Specification  3 Board Overview  4 Tutorial   o 4.1 Installation  o 4.2 Requirements  o 4.3 Sample Code  o 4.4 Expected Results  Introduction This is a photoelectric liquid level sensor that is operates using optical principles. The advantages of this are good sensitivity and no need for mechanical parts - meaning less calibration! The corrosion resistant probe is easily mounted and can handle high temperature and high pressure. The sensor is equipped with an interface adapter for compatibility with the DFRobot "Gravity" interface. Note: Avoid placing the sensor near bright lights or in direct sunlight as these can cause interference.
