Noncontact Liquid Level Sensor XKCY25T12V SKU: SEN0204 From Robot Wiki Contents 1 Introduction 2 Specification 3 Pin Description 4 Tutorial o 4.1 Requirements o 4.2 Connection Diagram o 4.3 Sample Code o 4.4 Results Introduction The non-contact liquid level sensor utilizes advanced signal processing technology by using a powerful chip with high-speed operation capacity to achieve non-contact liquid level detection. No contact with liquid makes the module suitable for hazardous applications such as detecting toxic substances, strong acid, strong alkali and all kinds of liquid in an airtight container under high pressure. There are no special requirements for the liquid or container and the sensor is easy to use and easy to install. The liquid level sensor is equipped with an interface adapter that makes it compatible with DFRobot "Gravity" interface. There are 4 levels of sensitivity which are set by pressing the SET button. Specification Operating Voltage (InVCC) : DC 5 ~ 24 v Current consumption: 5 mA Output voltage (high level) : InVCC Output voltage (low level) : 0V Output current: 1 ~ 50 mA Response time: 500 ms Operating Temperature : 0 ~ 105 Range for thickness of induction (sensitivity): 0 ~ 13 mm Humidity: 5% ~ 100% Material: ABS. Waterproof performance: IP67 Dimension : 28 * 28 mm / 1.1 * 1.1 inches Pin Description Liquid Level SensorXKCY25T12V Pin defination Num.
