OUT:control output;when detect moving objects,it will output high level
VIN:input voltage,4-28V
CDS:enable control chip,lower than 0.7V,OUT will output low level all the time
Ir Infrared Obstacle Avoidance Sensor Module
The sensor module adaptable to ambient light, having a pair of infrared emitting and receiving tubes, transmitting tubes emit infrared certain frequency, when the direction of an obstacle is detected (reflection surface), the infrared reflected is received by the reception tube, After a comparator circuit processing, the green light is on, but the signal output interface output digital signal (a low-level signal), you can adjust the detection distance knob potentiometer, the effective distance range of 2 ~ 30cm, the working voltage of 3.3V- 5V. Detection range of the sensor can be obtained by adjusting potentiometer, with little interference, easy to assemble, easy to use features, can be widely used in robot obstacle avoidance, avoidance car, line count, and black and white line tracking and many other occasions
Fingerprint Reader Sensor Module -Black
The AS608 Fingerprint Reader Sensor Module is capable of storing up to 128 individual fingerprints This module makes fingerprint recognition more accessible and easy to add to your projects. This means that it is super easy to make fingerprint collection, registration, comparison and search.
This module comes with FLASH memory to store the fingerprints and work with any microcontroller or system with TTL serial. This module can be added to security systems, door locks, time attendance systems, and much more.
The AS608 Fingerprint Reader Sensor Module take low-resolution snapshots of the tip of a finger and create arrays of identifiers that are then used to uniquely identify a given fingerprint.
LJ12A3-4-Z/BY Inductive Proximity Sensor
Inductive proximity sensors are a great way to precisely detect when a metal object is at a given distance. Since this is a non-contact sensor, it is ideally suited to situations where dust, dirt, or liquids may be present. This specific sensor triggers when the sensor tip is 4mm away and features an LED that also illuminates when the sensor is tripped. Mounting this sensor is quite easy & ndash; it has a long threaded body allowing for a considerable adjustment.
Internally this sensor is wired like an NPN transistor; the base pin of the transistor is triggered when the metal object is at a distance of 4mm. The sensor operates at 6 & ndash; 36VDC and will output the same voltage on the output wire. Because of the higher voltage, the output will need to have the logic level shifted to a lower voltage to operate with a Raspberry Pi or Arduino. To wire up this sensor: Brown = DC in: (6 & ndash; 36VDC) , Blue = Ground , Black = Output Signal.
