Pressure Sensor Interface
Hi fellows! Hope you all good. In this Lesson we are interfacing BMP180 with I2C bus. BMP180 is basically a digital Pressure Sensor. These types of sensors have pressure varies from 300 to 1100h. It can operate at 1.8 to 3.6 volts.
Pressure Sensor use for weather?
To realize these kinds of weather states generally connected with high and low pressure order. The movement of air in the atmosphere over and above plays a huge part in the weather. Essentially, when air cools at his peak position, which causes water vapor in the air to constrict into liquid water a tiny drops, sometimes making clouds and precipitation. Look toward this sinking air is related with melting and evaporated conditions.
Moderately ongoing passing air in low pressure induced air to intersect and it can’t move falling due to the surface, the air is imposed uphill, leading to moisture and related as discussed upward. The reverse cause with high pressure. Air is passing forward to high pressure center at the surface so as a result, air from upward must vanish. The surface flow is attended by the reverse behavior at higher levels of the atmosphere as shown in picture.
BMP180 Pin out:
BMP180 is basically a digital Pressure Sensor. These types of sensors have pressure varies from 300 to 1100h. It can operate at 1.8 to 3.6 volts.
|Vcc||Connected to 5v|
|Gnd||Connected to ground|
|Scl||Serial Clock pin|
|3.3v||Connecting 3.3V pin.|
ESP8266 interrelated with BMP180
As you see in the diagram you can use these two buttons to show the pressure on touchpad. The downward button will increase the pressure as show in lcd as well as the upward button will decrease the value. The total value varies 0 to 100.
So guys this is it. I hope we had a great experience with us. Stay connected to get this useful and interested topic.
