ITs a simple sensor which you can interface with any kind of Microcontroller like PIC, Atmel, Arduino or 8051 Microcontroller. The faulty IAT sensor tells the car's computer that the air in the intake is a different temperature than it actually is and may cause the vehicle to not deliver the proper fuel mixture to the engine. Interfacing of Temperature Sensor with Atmega 16 Introduction. Reading the Temperature from One DS18B20. Why Digital Electronics The 8051 Microcontroller? In this section you can learn and practice Digital Electronics Questions based on "The 8051 Microcontroller" and improve your skills in order to face the interview, competitive examination and various entrance test (CAT, GATE, GRE, MAT, Bank Exam, Railway Exam etc. • The sensor shall be supplied with either a 6 in cable for integral assembly or shall be supplied with 15 ft standard, maximum allowable cable 200 ft. 0 addr_b bit p2. Ambient temperature monitoring any change LM35 temperature sensor and the voltage at the output of digital information at the output of the ADC is displaced. I am trying to communicate to a MCP9801 temperature sensor via I2C using a 8051 microcontroller. The transistor will be in OFF state when the when the pin P2. com offers their Volkswagen Beetle parts catalog. This feature is not available right now. first sensor will sense temp then adc(0804) will convert it in dgital value and it display result 7-seg and store it on pc it on.

Interfacing of temperature sensor LM35 with Arduino. The DHT11 sensor provides 8 bits of precision for both humidity and temperature. These are stored in response to a problem found in the car by the system. In that, a DHT11 sensor is connected to P2. The circuit is implemented using ADC0804 andLM35.
