Arduino Sensor And ModulesR307 Optical Finger Print Scanner Reader Sensor Module In Pakistan
R307 R-307 R 307 fingerprint Sensor module For Arduino is a fingerprint sensor with a TTL UART interface. Professional optical technology, precise module manufacturing technic. The good image processing capabilities of Finger Print Reader can successfully capture an image up to resolution 500 dpi Finger detection function. The user can store the fingerprint 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 a 3.3 or 5v Microcontroller. A level converter (like MAX232) is required for interfacing with a PC serial port. R307 Fingerprint Scanner consists of a high-speed DSP processor, high-performance fingerprint alignment algorithm, high-capacity FLASH chips, and other hardware and software composition, stable performance, simple structure, with fingerprint entry, image processing, fingerprint matching, search and template storage, and other functions. The optical fingerprint detection device can be embedded into a variety of end products, such as access control, attendance, safety deposit box, car door locks.

R305 Fingerprint Scanner Module in Pakistan
This is R305 R-305 R305 Fingerprint For Arduino processing includes two processes: fingerprint registration process and fingerprint matching process (fingerprint matching which is divided into fingerprint matching (1: 1) and fingerprint search (1: N) in two ways]. When the fingerprint is registered, entry twice for each fingerprint, and processed the image, a composite template is stored in the module. Fingerprint matching, through the fingerprint sensor, entry the fingerprint image and processing, and then matching comparison with the module fingerprint template (if it is matched a template specified in the module, known as fingerprint matching, that is 1: 1 mode. If it is matched with multiple templates, it is called fingerprint search mode (1: N mode). The module gives the result of matching (pass or fail).

MQ135 Air Quality Detector Sensor Module in Pakistan
The MQ135 MQ-135 MQ 135 Air Quality Detector Sensor Module For Arduino has lower conductivity in clean air. When the target combustible gas exists, the conductivity of the sensor is higher along with the gas concentration rising. Convert change of conductivity to the corresponding output signal of gas concentration. The MQ135 MQ-135 MQ 135 gas sensor has a high sensitivity to Ammonia, Sulphide and Benzene steam, also sensitive to smoke and other harmful gases. It is at low cost and suitable for different applications such as harmful gases/smoke detection.
