Abstract
“MULTISENSOR SYSTEM USING LPC2148 MICROCONTROLLER’ is designed for sensing physical parameters such as temperature, distance and detection of object with the help of various analog sensors which can be helpful in various industrial applications and also in SMART home appliances. For temperature sensing, LM35DZ precision integrated- circuit temperature sensor is used which can take the input power in the range of 4 to 40V and gives the output in the range of 0 to 5.2V and operates in the range of 2°C to 150°C. For object detection TSOP1738 receiver and IR transmitter is used, which detects the presence of any obstacle between them. Since TSOP1738 carrier frequency is in the range of 38KHZ, an IR transmitter of same frequency range is needed which is designed using an IC 555 astable multivibrator. Proximity sensor is designed using an infrared emitter and detector pair which measures the distance of an object from the sensor. Its range is from 0 to 5cm. The outputs of the above mentioned sensors are interfaced with the ADC and the converted data is displayed on an LCD
