Reed Switch A reed switch sensor module is a sensor that closes the circuit in the presence of a magnetic field. Reed sensors can be used in many applications where contactless on/off is required. However, reed switches can be fragile to use directly, hence this module can make it easier to handle and mount the sensor in various applications. This module can be applied in Program-controlled switches, copiers, washing machines, refrigerators, cameras, Disinfection cabinet, door, window magnetic, electromagnetic relays, electronic weighing, level meter, gas meter, water meter and so on. Reed Switch Sensor Module consists of three pins i.e. VCC, GND, and DO. The digital out pin is connected to the output pin of the LM393 comparator IC. Using the Reed Switch sensor module with a microcontroller is very easy. Connect the Digital Output pin of the module to the Digital pin of Microcontroller. Connect VCC and GND pins to 5V and GND pins of Microcontroller. When the Reed Switch sensor detects the magnetic field, it closes the circuit and the digital pin of the module that is connected to the LM393 IC goes high. Applications: Photocopiers Washing machines, Refrigerators Door Magnets Electromagnetic Relays, Electronic Weighing devices, Level Meters, etc.

RepRap MK2B 3D printers Dual Power PCB HeatBed With 14AWG Cable (Red) A heatbed improves printing quality by helping to prevent warping. As extruded plastic cools, it shrinks slightly. When this shrinking process does not occur throughout a printed part evenly, the result is a warped part. This warping is commonly seen as corners being lifted off of the build platform. Printing on a heated bed allows the printed part to stay warm during the printing process and allow more even shrinking of the plastic as it cools below melting point. Heated beds usually yield higher quality finished builds with materials such as ABS and PLA. A heatbed can also allow users to print without rafts. This self-regulating heat bed provide a temperature controlled build platform ideally suited for printing with PLA or ABS. check out : 1.75mm Dark Blue ABS Filament -1Kg Connection: 12V connection: One cable connected to 1, another cable connected to a wire 2, 3 at the same time.

DC 5V 433Mhz RF Wireless Transmitter Module and Receiver Kit The TX-ASK is an effective low-cost solution for using the 433 MHz frequency. This ASK hybrid transmitter module is designed with a saw resonator, making it small, cost-effective, and easy to use for designing. However, it's important to note that this 433mhz rf transmitter and receiver kit does not support direct UART communication when connected to PCs or microcontrollers due to the high levels of noise on these frequencies. The RF module comprises a 433mhz rf transmitter and receiver. The transmitter receives serial data and wirelessly transmits it through RF via its antenna connected at pin4. The transmission rate can be set to 1kbps or 10kbps. The transmitted data is received by an RF receiver operating at the same frequency as the transmitter. This 433 MHz RF transmitter and receiver pair is cost-effective and can transmit signals up to 100 meters (although the antenna design, working environment, and supply voltage will significantly impact the effective distance). It's ideal for short-distance battery-powered device development. read more : RF 433 MHZ TRANSMITTER AND RECEIVER (WITH DEMO) Video Tutorial: Applications: Remote Controls Automation System Wireless Security System Sensor Reporting Car Security System Remote Keyless Entry
