How to Connect and Interface a Raspberry Pi With an Arduino

23/03/2018· Sometimes you may need to connect an Arduino to a Raspberry Pi. For example, if you have sensors, motors, and actuators, you can connect these to the Arduino and make the Arduino send values to and from the Raspberry Pi. This way, we can separate the computing intensive tasks (done by the Raspberry Pi) and controlling tasks (done by the Arduino).

CO2 Gas Sensor | Raspberry Pi - Arduino - Critics Corporation

This is the first CO2 sensor in Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released. It has MG-811 sensor module onboard which is highly sensitive to CO2 …

Configure and read out the Raspberry Pi gas sensor (MQ-X)

All MQ-X sensors return analogue signals, which we can not easily read at the Raspberry Pi. One possibility would be to use an Arduino, but we can also use an analog-to-digital converter (ADC), which can be read out via the I2C bus. In addition, we also need a logic level converter. Analog-Digital Converter (8 Ports): US * / UK *.
