HC SR04 HC-SR04 Ultrasonic Sensor also called HC-SR04 Ultrasonic Range Finder. Ultrasonic Sensor module HC-SR04 provides 2cm – 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules include ultrasonic transmitters, receiver and control circuit.

The PIR Motion Sensor Detector Module HC-SR501 allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor’s range. It is often referred to using “PIR”, “Pyroelectric”, “Passive Infrared” and “IR Motion” sensor. The module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It has a delay time adjustment Potentiometer and sensitivity adjustment Potentiometer. Repeat Trigger Selection solderable Jumper is also available.

Arduino KY-032 Obstacle avoidance sensor modules Infrared Obstacle Avoidance Sensor returns a signal when it detects an object in range. The range of the sensor is around 2-40 cm distance. It operates at 3.5 to 5 volts at around 20 milliamps. The Obstacle Avoidance Sensors usually come in two types – with 3 and 4 pins. This is the 4 pin version Sensor Module and has an optional Enable pin. An infrared obstacle avoidance sensor is designed to detect obstacles or the difference in reflective services.

Infrared IR Sensor Receiver Module for Arduino adopts 1838 infrared receiving head. Light resistance, strong electromagnetic interference, built-in infrared dedicated IC, can work under 500 lux light intensity.

MAX485 RS485 TTL To RS-485 MAX485CSA Transceiver Module is based on the Maxim MAX485 IC to allow serial communication over very long cable runs (up 4000 feet / 1200 meters). MAX485 converter board, serial data can be transmitted in both directions (half-duplex) at a data rate up to 2.5Mbps. The max485 TTL to rs485 converter module operates from a standard 5V power supply and uses 5V logic levels allowing them to be interfaced to the hardware serial ports of microcontrollers such as Arduino/PIC etc. The direction of communication can be controlled with just one digital pin (see diagram). RS485 to TTL module is also possible to connect multiple modules together for communication between 2 or more devices. For even greater distances two modules can be configured as a repeater.

Servo Motors are optimum-quality and affordable cost servos.! They are suitable for a wide range of applications, including RC aircraft, automobiles, and robotics, Or just to have some fun with whatever crazy project you’re working on.

Infrared detection controller, adopt an infrared detection way to control load switch.LED Lighting motion sensing switch which provides 1 to 10 minute OFF delay timing function. The sensor switch activates ON when a body in motion enters the field of view with an ON time hold that is adjustable from 1 to 10 minutes after motion has ceasedPIR (Passive InfraRed, IR) sensor has an effective range of 16 feet and diminished sensing of a moving human body to 26 feet.

Arduino heartbeat sensor or heart rate data can be used in many Electronic design and microcontroller projects. But the heart rate data is difficult to read, however, the Pulse Sensor Amped helps us to read heart rate. The Heart Beat Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.
