Red Laser Diode Module 650nm 5mW 6mm 5V lL2N4

You can easily control any device over the Internet through your phone, computer, etc.
The module can handle 5 users at the same time, it can work in two modes: STA (client) and AP (access point).
In AP mode, the module is connected via WIFI directly to your phone or computer (in open field can be up to 300 meters).
In STA mode, the relay module is connected to the access point (router) that supplies the network.
Wi-Fi in the room where the relays are located. In this case, the range mainly depends on the power of the access point antennas (routers).
You should not turn off after the configuration is completed, as some of the parameters of the WIFI module cannot be saved when power is cut off.

The pliers enable precise cutting and stripping of single and multi-core cables with diameters between 0.8 and 2.6 mm / 110-20 AWG.

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

It consists of three principles of induction of primary colors, if you know the composition of all types of color values, you can know the color of the test object.
For TCS230, a color filter is chosen, only a certain primary pass is allowed, it is stopped by another color. For example, when choosing a red filter, the incident light can only be stopped in red, blue and green, so you can get the intensity of the red beam of light.
For the same reason, the choice of other filters, can obtain the intensity of blue light and green light.
Through these three values, the color of the light can be projected onto a TCS230 sensor. Color Recognition Sensor GY-31 TCS230 TCS3200 features:
- Operating voltage: 3 - 5 VDC
- Model GY-91
- Chip TCS230 TCS3200
