1 x PIR Motion Sensor Detector Module HC SR501

A module which is used as potential divider to reduce any input voltage by a factor of 5.It is based on principle of resistive voltage divider design it can make the input voltage of red terminal reduce 5 times of original voltage.

It helps to measure environment temperature and pressure and barometric pressure.by which we can calculate altitude which can be used in various application like weather monitoring, navigation with I2C (“Wire”) interface. It measure the absolute pressure of the air around them how data are interpreted you can monitor change in weather, measure altitude. It has flexible supply voltage range with ultra low noise power consumption and low noise measurement.

Sharp Distance Sensor  2y0a02 is a distance measuring sensor unit. This sensor is great for sensing objects up to 5 feet away. It can be used for touch-less switch, sensor for energy saving, for detection of human body. It can also find the distance to objects that present a very narrow edge, It has Infrared Proximity Sensor and can measure  the distance form 20 cm to 150 cm .

The SW-520d Vibration sensor are lower power and easy to use. They are mostly used in toys, gadgets and appliances.  The switch when raised to 10-90 degree or shakes turns into "on position ". The pins have no polarity and can be interchanged.It is  completely airtight, waterproof, dustproof

The Vibration Sensor helps to detect the vibration of the surrounding environment that is normally open and comes with LM393 chip 0 with The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA having fixed bolt hole and is convenient to install. The sensitivity can be adjusted using the on board potentimeter. It has LEDs indicating for output and power.

TSL Gy -2561 Lux Sensor is a light sensor with flat response across most of the visible spectrum.  It measure both infrared and visible light to better approximate the response of human eye and capable of measuring both small and large amounts of light by changing the integration time. It has selectable detections modes. It has programmable interrupt function with user defined upper and lower threshold settings.

GY-45 MMA845x Sensor, digital triaxial modules is embedded functions with flexible user-programmable option. Its mostly used for Static orientation detection, E-compass application and many more. It has 14-bit and 8-bit digital output  with user selectable dynamic range of  ±2g/±4g/±8g. It easy to use . It has features of vibration detection and pulse detection.

The Sharp Distance Sensor 2y0a21 is wide angel distance measuring sensor with accurate measurment used for many DIY projects.  It has an analog output that varies from 3.1V at 10cm to 0.4V at 80cm.  It can be used for touch less switch, DIY robots. It is united with PSD infrared LED and signal processing circuit. The voltage output in this device is corresponding to the detection distance.

The Ultrasonic Ranging Module HC-SR04 is a distance measuring sensor that can measure with the accuracy range from 2 cm to 400 cm. Its ranging accuracy can be up to 3mm. It has stable performance with high density SMD board. It travels until the wave gets reflected to an object through which we can know the distance. It can be used for Security system, Object distance measurement and many more.

Infrared Sensors (IR) Module  is used to detect presence of any obstacle in front of the sensor module. It  has built-in IR transmitter and IR receiver , on board potentiometer .. Even in low light or in complete darkness the sensor has very good and stable response. It can be used for Obstacle avoidance in robots , Security systems and other object detection.It is stable and accurate with male header for easy connection.

The TCRT 5000 sensor module helps to detect color and distance.  It  has on board indicator LED and has good accuracy . It provides clean comparator output signal. To adjust the sensitivity on-board potentiometer is in-built. The bolt hole present for  easy installation . It can be used in detecting rainfall, liquid leakage etc. Its measuring distance is from 1 mm to 8 mm.
