The MQ-6 LPG Iso-Butane Propane Natural Gas Sensor makes it easy to monitor commonly used combustible gas concentration levels using our I2C Mini Module form factor. The MQ6 is connected to an ADC121C 12-Bit Analog to Digital converter, which is capably expanding to 9 gas sensors per I2C port using just two address jumpers (making full use of the floating address system).
The MQ-6 is capable of sensing Iso-Butane, LNG Natural Gas and LPG Propane air concentration levels between 200 and 10,000ppm. The ideal sensing condition for the MQ-6 LPG Iso-Butane Propane Natural Gas Sensor is 20°C ±2°C at 65% ±5% humidity. An internal preheater inside the sensor helps achieve the ideal sensing conditions, but the datasheet recommends over 24 hours for preheating to achieve optimal accuracy. Because of the internal preheater, this sensor requires more current than most of our I2C Mini-Modules. We measured 139ma for this I2C Mini Module so we strongly recommend planning the power strategy for your I2C master device to deliver no-less than 150ma per sensor! This sensor comes pre-calibrated to the datasheet’s recommended values; however, final calibration may be required for accurate measurements, as we do not stock the equipment for full-scale calibration of these sensors.
All I2C Mini Modules are designed to operate at 5VDC. Using a convenient 4-Pin plug, devices can be daisy-chained onto the I2C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application. Pull-up resistors are included with all DCube master devices. If you are wiring in your own I2C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.
What is the I2C Interface?
I2C Interface allows you to chain together several devices on the I2C bus, and communicate to each device individually at high speed (subject to the limitations of I2C). The I2C Interface uses a standard 4-Pin I2C Input and I2C Output connector. These devices communicate on the power of 5V I2C data and provide 5V DC power through this connector. The advanced embedded devices use standard I2C communications for all data transport, which is supported by nearly every microcontroller in production today. The I2C Interface is strictly a 5V standard, which is ideal for transport across longer cables. The device Package always includes a 6″ (152mm) 4-conductor I2C cable. The I2C based Mini Modules always include a 3″ (76mm) 4-conductor I2C cable. Cables and connectors are available separately for designers who would like to include their own I2C Interface into their designs.
Plug and Play Connectivity
These advanced Embedded devices will plug into any available I2C Output. This includes just about everything we make in the DCube Store IoT Category, including all the other IoT devices. We also supply a wide range of I2C adapters that make it easy to plug I2C Devices directly into most computing platforms. The advanced Interface adapters are available for Arduino, Banana Pi, BeagleBone, Bluz, C.H.I.P., ESP8266, Onion Omega, Particle Photon and Electron, PyCom, Raspberry Pi, 2, 3, and Zero, and Windows. We are always working to add new platform support for I2C devices. These Interface devices are compatible with just about everything in the microcontroller industry.
Unlimited I2C Expansion
Based on our plug-and-play I2C interface standard, all the I2C devices which are equipped with the above protocol output ports, making it easy to expand to a wide variety of sensors, current monitors, relay controllers, PWM controllers, and much more! We are always designing new expansions for our modular plug-and-play I2C framework. We are dedicated to building a product line of interconnected devices to simplify all forms of automation. Re-use or upgrade your hardware within seconds by selecting the modules that best fit your needs, and chaining them together using the included I2C expansion cables!
Powering I2C Interface Devices
Some I2C devices require an external power supply, others may be powered through the 4-Pin I2C bus connector at 5VDC, and other devices are jumper selectable between external and I2C bus power. All I2C mini-modules are powered through the 5V I2C bus connector, greatly simplifying connectivity.
