74HC195 ( 4-bit parallel access shift register) bluetoooth It works with supply voltage

It works with supply voltage from 3

NB:Focusable lens provides a sharply-defined field of view and increase detection distance

The TC output is normally LOW and goes HIGH when a circuit reaches zero in the count-downmode or reaches '15' in the count-up-mode

and operates in Normal or Power-Down Mode

K-Thermocouple- to-Digital Converter (0C to +1024C)Temperature sensor  (MAX6675)makes use of the Maxim MAX6675 K-Thermocouple to digital converter IC to provide a microcontroller compatible digital serial interface (SPI compatible) for giving an accurate temperature compensated measurement of the supplied K-Type thermocouple sensor

74HC195 ( 4-bit parallel access shift register) bluetoooth It works with supply voltageIntroduction : 74HC195 is a high speed 4 bit SHIFTREGISTER utilizes advanced silicon gate CMOS technolo gy to achieve the low power consumption and high noiseimmunity of standard CMOS integrated circuits, along withthe ability to drive 10 LS TTL loads at LS type speeds. This shift register features parallel inputs, parallel outputs, J Kserial inputs, SHIFT LOAD control input, and a directoverriding CLEAR. This shift register can operate in twomodes:
