Specification:
Condition: 100% Brand New
Item Type: Liquid Level Sensor Module
Material: Phenolic Plastic PlateWorking Voltage: DC5V
Output Mode 1: Analog Output 0-4.5v
Output Mode 2: High/Low Level Signal Output
Response Time: First, connect the wiring according to the picture. The wiring sequence is as shown in the figure. After the connection, the sensor module is powered by DC5V. The wiring method refers to the sensor module function profile. VCC is connected to the positive pole of the power supply, GND is connected to the negative pole of the power supply, and the one marked A is analog The output terminal, linearly corresponding to the level value of 0-3V, the design of the probe, can effectively detect the gradual value caused by the attachment of water, the detection level is highly controllable, the analog output voltage value can be collected by ADC conversion, and the collection method can use a dedicated AD Chips, such as ADC0809, etc.; labeled D is the level signal output terminal, the low level is active, the LED light is on, and the height of the tested solution can be set. For example, if it exceeds the set height level, it will alarm and output the level signal. The height alarm point (water shortage protection point) is adjusted by the blue potentiometer on the module. The default adjustment method is clockwise turbidity, and counterclockwise adjustment is small.
Product Introduction:The liquid level sensor uses the principle of infrared optics to transmit the detected liquid level and liquid level signals optically and convert them into electrical signal output. The voltage signal collected by the sensor is used to judge the liquid level. The sensor is compact in design and small in size. , Waterproof, cylindrical shape is convenient for drilling and installation; diversified installation methods, can be installed on top, bottom, side, and diagonal. The sensor head is smooth, easy to clean, and the accuracy is better than that of float type liquid level switches. The control accuracy is within ±0.5MM, while the existing commonly used float type liquid level switch has an accuracy of ±3.0MM; the principle of light, no friction and other mechanical moving parts, greatly increase the service life.
