Hello guys! I developed an app Android that comunicate with ECU Cars using OBD. Now i want to extend this project inserting inside car an Arduino and Raspberry Pi that support the ECU by extending the sensor lecture!
More precisely i want read this: -Internal and external temperature and humidity -Parking sensors -camera (maybe two, frontal and back) -CNG and GPL sensor for some lose of gas
For the camera and parking sensor i see that the difference can be the product but with temperature and gas sensor which are the best?
I see that exist the DH11 and DH22...or the temperature sensor that i have with the Arduino starter kit tmp35 (right?)... And for the gas exist the model MQ2...MQ4...MQ6 etc..
Finally, it's possible to make a bridge from the resistence that read fuel level tank and read that level from my Arduino without explode my car? ahahhah
