5V 7A 5 Pin SPDT subminiature High Power Relay PCB Mount
Original price was: ₹20.00.Current price is: ₹13.55. + GST

A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as making contacts, break contacts or combinations thereof. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters: they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations.

RFID RC522 13.56 MHZ Reader/Writer SPI S50 Card and Keychain
Original price was: ₹140.00.Current price is: ₹72.00. + GST

RFID (radio frequency identification) systems use data strings stored inside RFID tags or transponders) to uniquely identify people or objects when they are scanned by an RFID reader. Because passive tags require a strong RF field to operate, their effective range is limited to an area in close proximity to the RFID reader.

HC-SR501 PIR Sensor Infrared IR Body Motion Module
Original price was: ₹95.00.Current price is: ₹59.04. + GST

PIR Sensor is also called as Motion Sensor or Movement Sensor or is basically a Passive Infrared Sensor.

It is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin. It detect the ?motion by detecting the changes in the IR levels emitted from the object.It can be used as motion detector for security systems or robotics.

PZIN51000071 Imported Heart Rate Pulse Sensor Module
Original price was: ₹170.00.Current price is: ₹85.00. + GST

The working of the Pulse/Heart beat sensor is very simple. The sensor has two sides, on one side the LED is placed along with an ambient light sensor and on the other side we have some circuitry. This circuitry is responsible for the amplification and noise cancellation work. The LED on the front side of the sensor is placed over a vein in our human body. This can either be your Finger tip or you ear tips, but it should be placed directly on top of a vein.
