Red Laser Cross Module 650nm 5mW Head Point Adjustable Focal Length

This module adapted for the arduino is a light sensor. The resistance of the LDR cell decreases as the light intensity increases.
On the contrary in a dark environment, the resistance of the LDR cell increases accordingly. Characteristic: - 3-pin connector: 1- GND
2- VCC
3- analog output - the voltage depending on the light
- Supply voltage: 3.3 V-5VDC
- PCB size: 19x15x8 mm

Mobile Charger 5V 3A 3100mA  with connector USB-C. This power supply has an additional USB-A connector.

This photo-resistance module is very sensitive to ambient light. Activation of the microcontroller or retransmission modules,
The brightness module of the ambient light reach the set threshold, the output is high when the ambient light exceeds the set threshold.
The DO output can be connected directly to a microcontroller to detect the light environment and create a light control switch.
It has a speed range of 0% to 100%. Digital Light Intensity Sensor with Photo Resistance with LM393 Controller features:
- Operating voltage: 3.3 - 5 V
- Input current: 50 mA
- Use a very sensitive photo resistance
- Use a LM393 wide voltage comparator, high quality output signal
- Adjustable potentiometer can regulate the brightness of detected light

2x CNY70 Reflective Optical Sensor with Transistor Output features:
- Reflective optical sensor with transistor output
- Reflective optical coupler used to distinguish edge or line detection
- Dimensions of the housing are 7 x 7 x 6 mm
- Supply voltage: 5V
- Maximum diode current: 50 mA
- Maximum collector-emitter voltage: 32V

The module uses a 24-bit high precision A/D conversion chip HX711.
The input circuit can be configured to provide a bridge.
The electric bridge voltage sensor model (such as pressure, weight) is an ideal sampling module with high precision and low cost. HX711 Module Weighing Pressure Sensor 24 Bits features:
- Two selectable differential input channels
- Active low noise PGA with selectable gain of 32, 64 and 128
- Power supply regulator for load cell and ADC analog power supply
- Oscillator on chip that does not require external component with optional external glass
- Power-on-reset on the chip
- Simple serial control and serial interface: controls driven by pins, programming is not required
- Output data rate 10SPS or 80SPS selectable

Adjustable mounting bracket for laser diode that has a plate with holes to securely fix it to any surface.
It also has a screw to fix the laser diode and is adjustable in inclination, to obtain the perfect orientation of the diode. It can be used to support any object other than a laser diode that has a lower or equal diameter to the support.
Adjustable support for laser diode features:
- Inner diameter: 13mm,
- Includes 3 screws and 3 ankles to fix the support on a wall,
- Diameter of the base: 65mm,
- Unfolded support dimension: 110mm
- Weight: 61 gr.

It has an ON / OFF switch that will cut off power when you don't need it.
USB to Micro USB On/Off Switch Arduino Charger Cable features:
- Black color
