This is NRF24L01 2.4GHz Antenna Wireless Transceiver Module. The nRF24L01 is a highly integrated, ultra-low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz ISM (Industrial, Scientific, and Medical) band. With peak RX/TX currents lower than 14mA, a sub 26A power down mode, advanced power management, and a 1.9 to 3.6V supply range, the nRF24L01 provides a true ULP solution enabling months to years of battery life when running on coin cells or AA/AAA batteries. These RF modules are very popular among the Arduino tinkerers. The nRF24L01 is used on a wide variety of applications that require wireless control. They are transceivers which this means that each module can transmit and receive data.
Optocoupler 817 QUAD contains an IRED optically coupled to a phototransistor. It is packaged in a 4pin DIP, available in wide-lead spacing option and SMT gullwing lead-form option. Input-output isolation voltage(rms) is 5.0kV. Collector-emitter voltage is 80V(*) and CTR is 50% to 600% at input current of 5mA.

Photoelectric sensors are electronic devices capable of detecting the approximation, passage and presence of metallic materials or not, through emission and reception of infrared light provided they are located within the distance of actuation of the sensor. The detection of the photoelectric sensor occurs without physical contact between the sensor and the trigger because it has no moving parts subject to mechanical wear and thus increase the life of the equipment. The Photoelectric Sensor price base on the three operating principles Diffuse, Retroreflective, Barrier. Photoelectric sensor price model G18 with plastic housing has tubular shape with 18mm diameter (M18) with cable type or connector depending on type (diffuse, reflective or barrier) has sensing distances of 10, 30 cm, 2 and 5 m. Photoelectric sensor price has electrical configuration type NPN or PNP contacts normally open (NA), normally closed (NF) or (NA + NF) and connection with 2 or 4 pins.
This robust (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS FLASH-based 8-bit microcontroller packs Microchip’s robust PIC® architecture into a 40- or 44-pin package. It is upwards compatible with the PIC16C5X, PIC12CXXX and PIC16C7X devices. The PIC16F877A features 256 bytes of EEPROM data memory, self-programming, an ICD, 2 Comparators, 8 channels of 10-bit Analog-to-Digital (A/D) converter, 2 capture/compare/PWM functions, the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface (SPI™) or the 2-wire Inter-Integrated Circuit (I²C™) bus and a Universal Asynchronous Receiver Transmitter (USART). These features make it ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications.
PIC development board is powerful development platform for all versions of PIC microcontroller. It can be used for data logging, applications in real time data monitoring controll processes and interactive control panel sytems.
Piezo Pack of 5 Large Pickups 45mm Attach the round disc to the object that will be knocked on such as a door and measure the voltage across the two wires. Piezo elements can also produce sound when a voltage is applied across them. They convert between electricity and vibration in both ways; Vibration applied at the round end can be detected as a voltage across the wire leads and inversely, the voltage applied across the wire leads causes the round end to vibrate.
