Finger Print Sensor Module – R307
R307 is a finger print sensor module with TTL UART interface. The user can store the finger print data in the module and can configure it in 1:1 or 1: N mode for identifying the person.The FP module can directly interface with 3v3Â Microcontroller. A level converter (like MAX232) is required for interfacing with PC.
The R307 fingerprint module has two interface TTL UART and USB2.0, USB2.0 interface can be connected to the computer; RS232 interface is a TTL level, the default baud rate is 57600 , can be changed, refer to a communication protocol ; can And microcontroller, such as ARM, DSP and other serial devices with a connection, 3.3V 5V microcontroller can be connected directly. Needs to connect the computer level conversion, level conversion note , embodiments such as a MAX232 circuit.
Flame Sensor infrared Receiver Ignition source detection module
Flame Sensor Relay Module
It is a Flame Sensor Relay Module. The flame sensor can detect the flame or the wavelength at 760 nm to 1100 nm range of the light source, the test flame lighters distance of 80cm, the larger the flame, the greater the distance test. The detection angle of 60 degrees, the flame spectrum particularly sensitive Sensitivity adjustable (shown in blue digital potentiometer adjustment). The comparator output directly triggers the relay.
The output bluish Terminal Block for convenient connections.
Flat 1034 Mobile Phone Vibrator Motor
This Flat 1034 Mobile Phone Vibrator Motor is a shaftless vibration motor that is fully-enclosed with no exposed moving parts. Its small size (10 mm diameter, 3.4 mm height) and shaftless design mean you can mount it on a PCB or even place it in a pocket to add quiet, haptic feedback to your project.
The motor has a 3M adhesive backing on it for easy mounting and 1.5 leads for making quick connections. Polarity is not important; the motor can run CW or CCW. This tiny, button-type, vibrating motor shakes with a vibration amplitude of 0.75g and draws approximately 60mA when 3V is applied to its leads.
Flex Sensor – 2.2 inch
Flex Sensors are commonly used in Robotic Gloves and other Robotic Control application. It can be used to analyze how much a material is being bent. This flex sensor is 2.2 inch long and has two output leads which acts like a variable resistor. That is the resistance between two pins change based on how much the sensor is bent. It is commonly used along with another resistor to build a voltage divider circuit and then obtain a variable voltage based on the change in resistance of the sensor.
