General Ideas¶

This week I worked on defining my final project idea and started to getting used to the documentation process.

Flow Measurement¶

LPG used in household gas cylinders consists of 70% butane and 30% propane. LPG is a non-toxic gas. Neither LPG, nor the propane and butane it contains, has any toxic effects on the human body if inhaled. There is a common fallacy that LPG is toxic. Deaths occurring due to a LPG leakage happen not because LPG is toxic but because it reduces the amount of oxygen in the air since it is heavier than air.
The pressure of the cylinder gas varies between 2 and 3 bars depending on the ambient temperature; however, the operating pressure of the cylinders is designed to be 17.5 bars. If the pressure inside the cylinder exceeds 26.5 bars, the safety valve on the cylinder opens and the high-pressure gas is released, preventing the pressure in the gas cylinder from increasing further and the bottled gas from exploding.
For bottled gas to explode, the pressure inside the cylinder has to increase to very high levels (50 bars and above), the cylinder has to remain in fire for a certain period of time, or the safety valve has to fail to open. What is in fact meant in most of the news stories about “bottled gas explosions” in the media is the explosion of gas that is released into the environment and comes into contact.

The output voltage of the differential or gauge sensor increases with increasing pressure applied to the pressure side (P1) relative to the vacuum side (P2). Similarly, output voltage increases as increasing vacuum is applied to the vacuum side (P2) relative to the pressure side (P1).
The MPX10DP is a low-pressure differential sensor, typically used for medical applications. It is not designed for the high pressures and potentially explosive environments associated with household gas.

Code Example¶

Use the three backticks to separate code.

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}
