BMP180 Digital Barometric Pressure SensorBMP180 Digital Barometric Sensor Module will measure the absolute pressure of the environment using a digital barometer. Altitude can be measured with the help of pressure with an accuracy of 17cm. Using I2C, the device provides pressure and temperature as 16 bit values. Specification Vin 3 5 VDC Interface I2C Resolution 0. 03hPa 0. 25m Pressure sensing range 300 1100 hPa

Can range from 2

74HCT series ICs are High-speed logic gates with very low power consumption that utilize advanced silicon-gate CMOS

An internal temperature compensated reference

Relay are used where it is necessary to control a circuit by an independent low power signal  or where several circuit must be controlled by one signal
