Product Specification Product DescriptionThe LDR Sensor Module is used to detect the presence of light / measuring the intensity of light. The output of the module goes high in the presence of light and it becomes low in the absence of light. The sensitivity of the signal detection can be adjusted using potentiometer.


Features:-
Can detect ambient brightness and light intensityAdjustable sensitivity (via blue digital potentiometer adjustment)Operating voltage 3.3V-5VOutput Type                    Analog voltage output -A0                    Digital switching outputs (0 and 1) -D0With fixed bolt hole for easy installationSmall board PCB size: 3cm * 1.6cmPower indicator (red) and the digital switch output indicator (green)Using LM393 comparator chip, stable

Pin outs:-
External 3.3V-5V VCCExternal GND GNDDO digital output interface, a small plate (0 and 1)AO small board analog output interface

How to use:-
Photosensitive resistor module most sensitive to environmental light intensity is generally used to detect the ambient brightness and light intensity.Module light conditions or light intensity reach the set threshold, DO port output high, when the external ambient light intensity exceeds a set threshold, the module D0 output low;Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes;Digital output module DO  can directly drive the relay module, which can be composed of a photoelectric switch;Analog output module AO and AD modules can be connected through the AD converter, you can get a more accurate light intensity value

Product Specification Product DescriptionDescription : This is ISD1820 Recording Module Voice Board With On-Board Mic and Loud Speaker. The ISD1820 Recording Module Voice Board is the real easy way to add Voice Recording (and Playback) to your project. The Module can be operated directly by using the 3 Push-Buttons or with every microcontroller (ex. Arduino). A microphone is implemented directly on the board, and you can connect any 8 Ohm Speaker. Your recordings are saved even without power due to the non-volatile storage on the ISD1820. This module uses the ISD1820 voice record and playback IC to record a single voice message of up to 10 seconds in length. The recorded message is stored in its specialized analog flash memory that will keep the message stored even when power is removed. The module includes an electret microphone to record your message and push buttons to allow for the record, partial playback, or full playback of the message. Header pins allow for easy interface to a microcontroller and playback can be controlled with just one digital pin.

Additional Information

Description:

A laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. Unlike a regular diode, the goal of a laser diode is to recombine all carriers in the I region, and produce light. The laser head is composed of a light-emitting tube, condenser lens, and adjustable copper sleeve and it is assembled when delivered, the focal length of the lens is adjusted glued by a strong glue stick, which can work directly after connecting to a 5V DC power supply. Pay attention to the laser cell to prevent it from being burnt or from battery explosion due to a short circuit when removing the battery. The principle of laser emission and the specificity of the generation process determines the characteristics of laser which common light does not have: nice monochromaticity, coherence and directionality, and high brightness.

Specification:

• Working life: more than 1000 hours Spot mode: dot facula, continuous output
• Laser wavelength: 650nm (red)
• Light power: <5mW
• Supply Voltage: 5VDC
• Operating Current: <40mA
• Operating temperature: -36 ~ 65
• Storage temperature: -36 ~ 65
• Spot size: 15 meters spot for Ï10 mm ~ Ï15mm

Application:

• Electronic pointer: the teacher can use a laser pointer to indicate during teaching.
• Electronic level meter: the motor drives the head for rotation, and a straight line is projected on the wall for horizontal reference during decorating or posting pictures.
• Micro LCD projector: Remove the condenser so that the laser can produce a clear projection on the wall through the controllable LCD screen.
• Remote laser monitor: point the laser on the glass of the room to be monitored, receive the laser beam reflected back by the glass, and then detect the vibration of the glass to figure out sound in the room.
• Remote light-control anti-theft alarm: install laser diode and photosensitive resistance on one edge of the fish pond or watermelon patch to be protected and reflectors on the other three edges to form a protective zone.
• Remote laser wireless communication: place a pair of laser transceivers on two distant roofs facing each other respectively, you can send and receive files and even connect to the network with the use of the serial communication protocol of the microcontroller.
