Arduino Sensor And Modules

RGB full color LED Module KY009 KY 009 KY-009 for Arduino, emits a range of colors by mixing red, green, and blue light. The amount of each color is adjusted using PWM.

This module consists of a common cathode 5mm Red/Green LED and a 0Ω resistor, Since the operating voltage is 2.0v ~2.5v you’ll need to use limiting resistors to prevent burnout when connecting to the Arduino.

KY015 Ky 015 KY-015 Arduino DHT11 DHT 11 DHT-11  temperature and humidity sensor module provide a digital serial interface to measure humidity and temperature.

This module consists of a 5mm RGB LED and three 150Ω limiting resistors to prevent burnout. Adjusting the PWM signal on each color pin will result in different colors.

Arduino IR receiver module KY022 KY 022 KY-022 reacts to 38kHz infrared light. Infrared IR Sensor Receiver Module for Arduino adopts an 1838 infrared receiving head. Light resistance, strong electromagnetic interference, built-in infrared dedicated IC, can work under 500 lux light intensity.

KY023 KY 023 KY-023 Arduino joystick module, uses a biaxial potentiometer to control the X and Y-axis. When pushed down, it activates a switch. Based on the PS2 controller’s joystick, it’s used to control a wide range of projects from RC vehicles to color LEDs.

Arduino KY-027 Magic Light Cup Module is a set of two boards, each one has a led and a mercury tilt switch. Using PWM to drive the LEDs on each module you can achieve the effect of light being “magically” transferred from one module to the other when tilting them.

Digital Temperature Sensor KY-028 for Arduino, measures temperature changes based on the thermistor resistance. This module has both digital and analog outputs, there’s a potentiometer to adjusts the detection threshold on the digital interface.

The KY033 KY 033 KY-033 Tracking sensor TCRT5000 infrared sensor continuously emits an infrared emitting diode when there is no reflected or TCRT 5000 reflected infrared light, but the intensity is not large enough, the phototransistor is already in the off state, the output end of the module is high, indicating that the diode is always off; in the detection range to be detected In the object, the intensity of the TCRT-5000 reflected infrared ray is large enough, the phototransistor is saturated, the output of the module is low, and the indicator light is illuminated.

This is a touch sensor to detect contact with charged bodies like human fingers and so on. These sensors are used in touch screens, you can use them to implement your own touch screen and your security system. Another application is to create an electrical safety switch, that prevents people from electrification, so whenever an electric conductor is touched by a charged object (human), the electricity will go OFF.
