OV5647 5MP 1080P IR-Cut Camera for Raspberry Pi 3/4 with Automatic Day Night Mode
The OV5647 5MP 1080P IR-Cut Camera for Raspberry Pi 3 and 4 with Automatic Day Night Mode Switching is a custom designed add-on for Raspberry Pi. It attaches to Raspberry Pi by way of one of the small sockets on the board upper surface. This uses the dedicated Raspberry Pi's onboard CSI interface, designed especially for interfacing to cameras.
OV7670 Camera Module
OV7670 Camera Module is a precise small size, high sensitive and low voltage CMOS image Sensor module for capturing and processing the image. It is based on OV7670 image sensor. Through SCCB bus control, the sensor can output the whole frame, sampling, and various resolution of 8 bits of data. The product VGA image can reach up to a maximum of 30 frames per second. Users can completely control the image quality, data format and transmission mode. All the process of image processing functions can be through the SCCB programming interface, including gamma curve, white balance, saturation and chroma.
P31 Water Level Sensor Plastic Float Switch
A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. It is a simple structure, easy to use level control device; moreover, it is neither a complicated circuit nor does it provide power. This switch has a mechanical switch than the average small sized switches

P80C51 Microcontroller – 8 Bit – 40 Pin
The 80C51 has separate address spaces for program and data memory. The Program memory can be up to 64k bytes long. The lower 4k can reside on-chip. Figure 1 shows a map of the 80C51 program memory. The 80C51 can address up to 64k bytes of data memory to the chip. The MOVX instruction is used to access the external data memory. The 80C51 has 128 bytes of on-chip RAM, plus a number of special function Registers (SFRs). The lower 128 bytes of RAM can be accessed either by direct addressing (MOV data addr) or by indirect addressing (MOV @Ri).
P89V51RD2 Microcontroller
The P89V51RD2 is an 80C51 microcontroller by NXP (Phillips) with 64 kB Flash and 1024 bytes of data RAM. A key feature of the P89V51RD2 is its X2 mode option. The design engineer can choose to run the application with the conventional 80C51 clock rate (12 clocks per machine cycle) or select the X2 mode (6 clocks per machine cycle) to achieve twice the throughput at the same clock frequency. Another way to benefit from this feature is to keep the same performance by reducing the clock frequency by half, thus dramatically reducing the EMI.
PAM8403 5V 2-Channel Stereo Audio Amplifier Module
This Audio Amplifier Module is based on PAM8403 which is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area.
With the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB cousins. It can extend the battery life, which makes it well-suited for portable applications.
PAM8403 Mini 5V Audio Amplifier Board with Switch Potentiomete
This is PAM8403 Mini 5V Digital Amplifier Board With Switch Potentiometer. PAM8403 is a small digital amplifier chip, high-definition sound quality highlights the advantages of digital chips, the circuit using the most reasonable peripheral configuration, power supply filtering is upgraded to 470uf (some sellers are less did not even 100uf capacitance).
1.6mm glass sheet, the real amplifier board did the most detailed, high-fidelity sound output 3W + 3W, is a rare good product enthusiasts amplifier, potentiometer using the original anti-meter body, potentiometer with the switch can cut off the power supply directly counterclockwise
PAM8406 Digital Amplifier Module With Volume Control Potentiometer 5W – 2 Stereo
PAM8610 Stereo Audio Amplifier Board with Switch Potentiometer
The power amplifier circuit board designed using the official standard. the chip uses a selection of US imports original Longding micro Class D amplifier chip. Good product chip is necessary and the majority of music lovers to share. this is our consistent philosophy! The amplifier with ultra-high efficiency. large power. in the case of 12V power supply can output 10W + 10W of power. the chip without fins. but also with overheating. over-current protection function. the function can be said to be very powerful.
Panasonic Passive Infrared (PIR) Wall Installation Type Motion Sensor
PIR (Passive Infrared or Pyroelectric) Motion Sensor from Panasonic has industrial grade, highly reliable and precise and accurate sensor.
The PIR sensor detects infra-red radiation in the low infrared spectrum (10m wavelength) which is emitted by human movement. The sensors are able to detect a change in temperature from object to ambient from as little as 3C. Changes in the level of detected emission are evaluated by a window comparator, and if the change exceeds the upper or lower threshold the output level of the sensor goes high and can be used to trigger external circuitry.
