1, according to the spectral characteristics of three photoresistor photoresistor: UV light-sensitive resistors, infrared light-sensitive resistors,

Visible photoresistor;

2, the main parameters are as follows:

A, dark current, the dark resistance: photoresistor at a certain applied voltage, when no light irradiation, when flowing

Current is called dark current. Applied voltage and the dark current ratio is called dark resistance;

B, Sensitivity: Sensitivity refers to the resistance value of the photoresistor from light irradiation (dark resistance) when irradiated with light and the

Resistance (light resistance) of the relative change value.

C, voltage characteristic curve. Volt-ampere characteristic curve used to describe the relationship between the applied voltage and the photoresistor photocurrent, of

The photosensitive device, its photocurrent increases with the applied voltage.

D, the temperature coefficient. Photoelectric effect photoresistor influenced by temperature, partial photoresistor optoelectronic at low temperatures

Higher sensitivity, whereas the sensitivity at high temperatures are lower.

E, rated power. Refers to the rated power for a certain line photoresistor allowed power consumed, when the temperature rise

High, its power consumption is reduced.

Line-finding sensor module KY-033 for

KY-033 tracking path DIY kit tracking module of intelligent probe car infrared detection sensor channel 3 pins

We will issue a new version of the product with upgraded functions. It may have different shapes or colors. If you can't agree, please don't buy. Please select the available tracking information transportation method, and don't ask for a tracking number, if your transportation method is unavailable.

1。 Detection distance, test white paper about 2cm. Different colors, different distances, whiter.

2。 Power supply voltage: 2.5V ~ 12V, no more than 12V (Note: if the power supply voltage is low or too high, the life of the sensor will be shortened, and the 5 V power supply is the preferred power supply).

3. Working current, 5 V 18-20ma. After many tests, the sensor hardware is set to the best performance of 18 mA and 20 mA at present, which is mainly manifested in capacity interference resistance. If you need low power consumption, we can modify it, at least they can do 5mA. You can display a message.

4。 The detected object, the final output signal level is low; No object is detected, and the final output signal is high.

5。 TTL level sensor output can be directly connected with 3.3v or 5v of MCU IO port.
