Reed Switch Sensor Module
A reed switch is a sensor that closes circuit in the presence of a magnetic field. Reed sensors can be used in many application where contact less On/Off is required. However reed switches can be fragile to use directly, hence this module can make it easier to handle and mount the sensor in various applications.

RGB 3 Color LED Module
This module consists of a 5mm RGB LED and three 150Ω limiting resistors to prevent burnout. Adjusting the PWM signal on each color pin will result in different colors.
This is a DIP 3 Color LED Module. Through the PWM adjusting, three primary colors can be mixed to obtain different colors.
Connect the red pin (R) on the KY-016 to pin 11 on the Arduino. Blue (B) to pin 10, green (G) to pin 9 and ground (-) to GND. Notice that you do not need to use limiting resistors since they are already included on the board.
RS232 to TTL Serial Interface Module – 4 Pin
RS232 to TTL SP3232 UART Transceiver Communication Serial Module
RS422 to TTL Power Supply Converter Board
RS422 interface, two-way communication. B Y Z A ultra far transmission 1000 meters. The module has ESD 15KV protection. Onboard to increase the limit of 10 ohms current limiting current protection. Module with TVS diode. Anti lightning, peak voltage. The module has 120-ohm termination resistors, which can effectively reduce the interference of long-range communication. Have the power indicator light and the data receiving and sending indicator light. Panoramic view of state data. Module TTL side using 5V DC power supply TXD RXD compatible with 5V logic signal.
RS485 to TTL Converter Module Serial Port UART Hardware Automatic Flow Control Module
RS485 to TTL Converter Module Serial Port UART Hardware Automatic Flow Control Module is based of MAX485 chip, which is one of the most relied on when working with RS485 Bus. This module supports 3.3 V and 5V power supplies, and TTL Levels. It can connect and identify up to 128 nodes on the RS485 bus. This module also supports very long range of the bus.
S9006 HDPE Motion Detector Lens for PIR sensor Module
The S9006 HDPE Motion Detector Lens is an optical element, one side is smooth, another side is by a ring a part of concentric garden composition. Fresnel lens arrays designed for Passive Infrared Sensor. The optical surface increases lens sensitivity for the PIR sensor application. All the PIR sensor must work with the Fresnel Lens.

SCT-013-000 100A Non-Invasive AC Current Sensor Split Core Type Clamp Meter Sensor
This is SCT 013 000 100A Non-Invasive AC Current Sensor Split Core Type Clamp Meter Sensor. SCT-013-000 is a Non-Invasive AC current sensor i.e. it is a current transformer which can be used to measure AC current up to 100 amperes.
Current transformers(CTs) are sensors are for measuring alternating current. They are particularly useful for measuring whole building electricity consumption (or generation for that matter). The split core type such as the SCT-013-000 in the picture is particularly suitable for DIY use. Clip this SCT 013 000 straight on to either the live or neutral wire coming into the building without having to do any high voltage electrical work.
