Arduino - Motion Sensor | Arduino Tutorial

Arduino - HC-SR501 Motion Sensor When an Arduino's pin is configured as a digital input, It can read the state (LOW or HIGH) of anything it connected to. By connecting the Arduino's pin with the OUTPUT pin of the HC-SR501 sensor, we can use the Arduino code to check the value of the OUTPUT pin to detect the motion.

CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno

· This simple project uses the Arduino Uno and the MQ7 Gas Sensor to sense the concentration of CO (Carbon Monoxide) in the air. The MQ7 requires a heater voltage that cycles between 5v (60s) and (90s), drawing approximately 150mA at 5v which exceeds the power capacity of the Uno, so I use the KA278RA05C adjustable voltage regulator to drive this.

11. Arduino-Projekt: CO2-Messung mit dem Sensor ... - blikk

· Der CO2-Gehalt der Luft wird in PPMs (Parts per Million) angegeben. 1 ppm entspricht bei Gasen 1 µL pro Liter Gas. Normale Luft hat etwa 400 ppm CO2-Gehalt, das entspricht 0,04% CO2-Anteil. Der Sensor funktioniert mit Spannungen bis 5,5 V und besitzt 5V-kompatible Signalein- und -ausgänge, was wichtig für den Betrieb am Arduino ist.

Carbon Monoxide Gas Sensor MQ-7 - Arduino Project Hub

I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ-7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.
