Arduino Gas Sensor for Research
Budget: $15 – $25 USD
I'm working on a research project and need an Arduino gas sensor to detect Carbon dioxide, Carbon monoxide, and NOx. The sensor will need to have capabilities for data logging and real-time alerts.
Okay so using the arduino nano ESP32, I want to connect up a MICS-6814 gas sensor and run some code in which it detects the level of CO2, CO and other pollutants and then light up, either a green, amber or red LED depending on the air quality, green being good, amber being okay and red being poor. I have wired this up as follows which to my understanding is correct (but perhaps not):
can you modify the code to include where I've added the inputs. So, the +5v on the sensor is connected to the VBUS on the arduino as it is powered by USB, the NO2 is connected to A1 input, the NH3 is connected to A2 input and the CO is connected to the A3 input. The Green LED is connected to D12, the amber LED is connected to D8 and the red LED is connected to D3 and they are all grounded through a 220 Ohm resistor. An image can be provided.
I have some code which seems to upload to the arduino correctly but it does not perform the function.
Ideal skills for this project include:
- Expertise in Arduino programming and hardware integration.
- Experience with gas sensors, particularly for the gases mentioned.
- Skills in setting up data logging and alert systems.
