Gas detection for Raspberry Pi using ADS1x15 and MQ-2 sensors.

Description

The MQ-2 sensor can detect multiple gases (CO, H2, CH4, LPG, propane, alcohol, smoke) and outputs analog voltage. This project can convert it to digital using ADS1015 or ADS1115 and filter out the target gases.

The sensor can be inaccurate so don't use those measurements if you need them for security purposes. Use some professional measurement device if you need to do this.

Usage

The detection class uses ADS1115 and it's I2C address 0x48 by default. It assumes the sensor is connected to P0. You can also pass them to arguments.

The ro value is about 1000, but it needs to be calibrated. This is done automatically if it is not specified. The calibration must be done in good fresh air to make measurements more accurate. Alternativly, you can save the calibration value and later pass it as ro argument.

from gas_detection import GasDetection

detection = GasDetection()

You can then read percentage of gases in parts per million (ppm). The measurements are returned as dictionary and gas be accessed by GAS_XX constant.

ppm = detection.percentage()

print('CO: {} ppm'.format(ppm[detection.CO_GAS]))
print('H2: {} ppm'.format(ppm[detection.H2_GAS]))
print('CH4: {} ppm'.format(ppm[detection.CH4_GAS]))
print('LPG: {} ppm'.format(ppm[detection.LPG_GAS]))
print('PROPANE: {} ppm'.format(ppm[detection.PROPANE_GAS]))
print('ALCOHOL: {} ppm'.format(ppm[detection.ALCOHOL_GAS]))
print('SMOKE: {} ppm\n'.format(ppm[detection.SMOKE_GAS]))

You can also look to example file for more examples. For more details how the values are calculated you can read tutorial on Raspberry Pi Tutorials.

    Hi @filips123

    Thanks for the great library!

    It would be very nice to have the possibility to choose between the percentage output and maybe something more "readable" like this kind of output.

    OPCUA and GasDetection

    Hello! I want to use this package for OPCUA Client and Server and I don't know how to use this module for getting value from sensor and publish this in the cloud platform. could you please help me? this is my server python code. "X" is the part for MQ2 module and I have to complete this.

    from opcua import Server import time from gas_detection import GasDetection

    X = MQ2

    server = Server() url = "opc.tcp://xxx.xxx.x.xxx:4840" server.set_endpoint(url)

    name = "OPCUA server" addSpace = server.register_namespace(name)

    node = server.get_objects_node() param = node.add_object(addSpace, "Parameters")

    var = param.add_variable(addSpace, "Variable", X) var.set_writable()

    server.start()

    try: while True:

        v = var.get_value()

    print("Variable =" .format(v))

    time.sleep(0.25)

    except KeyboardInterrupt: print('\nAborted by user!')
