Panthon tuyết giọt mưa Mô-đun cảm biến phát hiện mưa mô-đun thời tiết độ ẩm cho linh kiện điện tử tự làm

Features:
1.Use high-quality materials with guaranteed quality
2.Small and beautiful size
3.Gold sinking process for corrosion resistance
4.1MM ultra-fine spacing has high sensitivity and can react quickly when mixed with atomized liquid
5.Double sided design, who uses one side for a long time? After oxidation, the other side can still be used, saving costs

Parameters:
Product name: Rain and snow detection board (probe)
Ruler: 56 * 38 * 1.2mm
Voltage: DC3-12V
Interface: No polarity differentiation
Purpose: To detect highly condensed liquids such as condensation/water droplets.
Principle: The probe is connected to the positive and negative electrodes to form an electrode. As the humidity of the panel increases, the resistance between the two poles decreases. Can be connected to voltage comparison circuit or AD detection

Instructions:
1.This probe is an analog resistor, and when there is no moisture on the surface of the probe, the resistance value is infinite. When there is moisture, the resistance decreases with increasing humidity.
2.It can be connected to the sensor motherboard for use, or can be connected to AD for microcontroller detection.
3.It cannot be used for detecting acidic and corrosive chemical liquids and oils, which can easily lead to rapid corrosion of the panel or accidents.
4.The panel electrode adopts the process of spraying tin and depositing gold, which will oxidize and gradually corrode after use, and is considered a consumable product. The specific service life is related to the voltage and frequency of use. The lower the voltage, the less contact with water, and the longer the service life.
