6/5/2021· MQ2 Reading different gases. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000.
MQ2 Gas sensor is used to detect the gas level around the area. This sensor able to use as home or factory gas leak monitoring, suitable for gas, butane, propane, methane, alcohol, hydrogen, smoke and other monitoring devices. Specification: Size: 35mm x 22mm x 23mm (length x width x height) Main chip: LM393, ZYMQ2 gas sensors
Creating 2D graphs to demonstrate mathematical concepts, visualize statistics, or monitor sensor data can be accomplished in just a few lines of code with matplotlib. The Raspberry Pi is a great platform for connecting sensors (thanks to the exposed GPIO pins), collecting data via Python, and displaying live plots on a monitor.
29/12/2015· The python code is shamelessly modified from the Adafruit I2C ADS1115 library example code. Next up, modifying the Python code to display parts per million (PPM) instead of voltage from the sensors. After that''s working, I''m going to solder the ADS1115 ADCs to a permaproto board along with all the sensor wiring.
MQ2 sensor. MQ2 is one of the commonly used gas sensors in MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors as the detection is based upon change of resistance of the sensing material when the Gas comes in contact with the material. Using a simple voltage divider network, concentrations of ...
