Non-Contact Liquid Level Sensor Water Alarm Induction Switch Detector DC 5-30V

Description: Non-Contact Liquid Level Sensor Water Alarm Induction Switch Detector DC 5-30V ParameterInput voltage: DC 5-30VResponse time: 500MsLevel Error: ±1.5mmWire length: 1.2m(47 inches)Humidity: 5% ~ 100%Material: ABSWaterproof level: IP65Operating temperature: -5℃ ~ 105℃ Wiring: Brown=power "+" , Blue=power "-" , Black=signal , White="NPN normally open"(when hang up) or "NPN normally closed"(when white and blue wires connected together)Sensor sensitivity adjustmentCounterclockwise adjustment increases the sensing distance, and clockwise adjustment decreases the distanceThe sensor can sense human hands, so it is recommended to adjust the sensor after installing it in a fixed position to avoid human hands appearing in the sensing rangeMeasuring output voltage The sensor is NPN normally open output , collector open output, when no load is connected and only a multimeter is used for measurement, the high level value is virtual electricity and has no practical significance. The sensor should be connected to a load less than 0.2A(alarm light , small relay,pull-up resistor, optocoupler...etc...), then use a multimeter to measure the output terminal, and the data will be valid. "Normal Open": Output signal when liquid is detected ; "Normal Closed": Output signal when no liquid is detected Please pay attention to high level problem when connect to microcontroller or PLC For example: the sensor powered by 12V needs to be connected to a 5V microcontroller, the brown wire connect to 12V power "+", the blue wire connect to 12V power "-", after the black wire is connected to a 10k resistor and pulled to a 5V voltage, the black wire is now at 5V high and low level.
