It only needs to write data to a specific address through the IIC method, with 8-level grayscale display. It is suitable for making digital tube displays such as counters, frequency meters, stopwatches, etc.
This photoresistor sensor is sensitive to ambient light intensity. It is generally used to detect the brightness and light intensity of the surrounding environment. It can sense the light source in a fixed direction. When connected to the controller, it can read the ambient light intensity and can be made into a photoelectric switch. The photoresistor is A resistor made using the photoelectric effect of semiconductors whose resistance value changes with the intensity of incident light; when the incident light is strong, the resistance decreases, and when the incident light is weak, the resistance increases. Photoresistors are generally used for light measurement, light control and photoelectric conversion (converting changes in light into changes in electricity). Commonly used photoresistors are cadmium sulfide photoresistors, which are made of semiconductor materials. The resistance of the photoresistor changes with the intensity of the incident light (visible light). Under dark conditions, its resistance (dark resistance) can reach 1~10M ohms. Under strong light conditions (100LX), its resistance The value (bright resistance) is only a few hundred to thousands of ohms. The sensitivity of the photoresistor to light (ie, the spectral characteristics) is very close to the response of the human eye to visible light (0.4~0.76) μm. As long as the light that the human eye can feel will cause its resistance to change.
This sensor is a capacitive point-type trigger sensor based on a touch detection IC (TTP23B). Under normal conditions, the sensor outputs low level. This mode is a low power consumption mode. When the finger touches the corresponding position, the module outputs high level. The sensor can be installed on non-metallic materials, which can avoid the troubles caused by traditional push buttons.
This touch sensor uses high-quality mouse switches and has a long service life. This sensor integrates a power indicator light to clearly check the working status. The output is low when touched and remains high when released; it can be used for collision detection and contact collision detection of smart cars and robots.
This module is a simple moisture sensor that can be used to detect soil moisture. When the soil is short of water, the sensor output value will decrease, and vice versa. Use this sensor to make an automatic flower watering device, which can be used when you are not available for a long time. At home or after the watering time, it can sense whether your plants are thirsty. Prevent the plants from withering before you know it is caused by lack of water. Cooperate with the Arduino controller to make your plants more comfortable and your garden smarter.
The human body induction sensor can detect infrared rays emitted by moving people or animals and output switching signals. It can be used in various situations where moving human bodies need to be detected. Traditional pyroelectric infrared sensors require human body pyroelectric infrared probes, dedicated chips and complex peripheral circuits to implement. They are slightly larger in size, complex in circuit and slightly less reliable. Our newly launched infrared pyroelectric motion sensor is specially designed for Arduino. It adopts a digital integrated human body pyroelectric infrared probe and has the characteristics of small size, high reliability, low power consumption and simple peripheral circuit. Application scope: moving human body detection, occupancy detection, infrared anti-theft system, etc.
This sound sensor is an analog output and uses a high-precision MIC to collect sound source amplification, timbre, frequency and other information; combined with the main control and power amplifier, it can be built into a sound amplifier.
This tilt sensor uses a high-precision sw200D switch, which can detect tilt in one direction and send out a signal when there is tilt. Note that this sensor can only detect whether there is tilt, and cannot detect the degree of tilt.
The buzzer is an electronic sounder with an integrated structure. It is powered by DC power and is widely used as a sound-generating device in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products. .
The active buzzer can sound continuously when directly connected to a 5V rated power supply. This module can be used in conjunction with the Arduino motherboard to complete the design of simple circuits and achieve “plug and play”.
Passive buzzers can emit various sounds by inputting signals of specific frequencies, and can be connected to the motherboard to make various electronic keyboards.
