Arduino Uno R3 Nano V3.0 Mega 2560 Mega 328 Kit

Features

• 1-channel relay module: controlled by the microcontroller via a 5 V digital output. With display of the current and the action of the relay. Used as home appliance control
• PIR motion sensor: the passive infrared sensor is an electronic sensor that detects infrared radiation radiated by objects in its field of vision. These sensors are widely used as motion detectors
• SG90 9G servo motor: used for remote controlled helicopters, micro robots, boats and other types of arduino toys or experiments
• DHT11: The digital temperature and humidity sensor is a digital signal output with a combined sensor of temperature and humidity calibrated
• Soil moisture sensor: In general, soil moisture is the most sensitive to moisture ambient
• JoyStick module: 2-axis rocker module with joystick potentiometer with 2-axis analog output (X, Y), digital output 1-button (Z).
• Red LED diode: Common anode
• Digital display: 4 digits; 4 bit 7 segment
• Ultrasonic distance sensor: use I / O trigger for a high level signal of at least 10us, when activated it sends a series of ultrasonic pulses at 40 kHz and receives the echo from an object
