Product introduction:
It is necessary to measure the liquid level in many occasions such as drinking fountains, water purifiers, humidifiers and other electrical equipment, agriculture, aquaculture and industrial control. This contact type photoelectric liquid level sensor is designed using optical principles. This sensor has the characteristics of simple structure and high positioning accuracy. The sensor has no mechanical parts, no additional debugging, and has high sensitivity, low power consumption, corrosion resistance, high pressure resistance, high temperature resistance, and stable chemical properties. The probe is small in size and compact in structure. It can be installed up, down, sideways and obliquely in multiple directions to detect overflow, dry up and horizontal liquid level. Can be used as a reminder and alarm function. It adopts built-in emitting diode and phototransistor, so it has a long service life. The live parts are completely isolated from the controlled liquid, so there is no safety hazard. Supporting sensor module interface is 4 Pin XH-2.54 interface Product parameters: Working voltage: 5.00V DC Working current: <12mA (MAX) Working temperature: -25~105(°C) Low level output: <0.1V High level output: >4.6V Liquid level detection accuracy: soil 0.5mm Life: 3000h Module size: 38.6mm*22.lmm Sensor interface: XH2.54 Module introduction and pin definition: The composition of the liquid level sensor module is shown in the figure below. The module is connected to the liquid f sensor through a 4Pin XH-2.54 connector. Adjust the knob of the 10K blue potentiometer to adjust the digital output trigger threshold. VCC: supply voltage +, 5V, 3.3V cannot be used AO: analog signal output, output voltage range 0-5V DO: Digital signal output, output high level when less than the set value, output low level when greater than the set value GND: supply voltage- Introduction of supporting liquid level sensor The sensor module supporting liquid level sensor model is FS-IR02. White: Phototransistor collector Blue: anode of infrared emitting diode Yellow: Phototransistor emitter Red: cathode of infrared emitting diode Instructions: 1. Sensor installation: 2. Use analog signals: You can use the AO port (analog output terminal) of the module to connect to the AD port of the single-chip microcomputer or a dedicated AD conversion chip to analyze the data after sampling the voltage data. It can be sampled every 0.1 second. When the voltage of 10 consecutive samples is greater than 0.15V, it is considered that there is no water, and when the voltage of 10 consecutive samples is less than 0.15V, it is considered that there is water. The diamond-shaped design of the probe can effectively detect the gradual value caused by the attachment of water, and the detection level is controllable. In this way, the environment with steam can be solved, and the problem of scale is also solved: at the same time, we must remember: liquid level switch The tail of the switch must be kept dry, and do not let water vapor rush into the switch, otherwise it will fail. 3. Use digital signals: Use the DO port (digital output terminal) of the module to adjust the height level alarm output level signal set by the potentiometer knob (DO port outputs low level when there is water, and DO port outputs high level when there is no water). Sensor module The DO port is connected to the 1/0 port of the single-chip microcomputer for output signal judgment or connected to an external drive circuit to drive other devices. Note: 1. The liquid level sensor is based on infrared optical principle, so high voltage or short circuit should not be used when wiring. Otherwise it will burn the sensor. 2. The tail of the liquid level switch must be kept dry, and do not let water vapor escape into the switch, otherwise it will malfunction. Reference circuit:
