SENS-GAS-KIT Gas Sensor Plug n’ Play Kit

SENS-GAS-KIT Gas Sensor Plug n’ Play Kit

This kit comes with 9 gas sensors that have various detection of gas concentration levels. Simple plug and play feature allows you to start recording data down by plugging in three cables into any Arduino microcontroller. This unit has four pinouts and an adjustable potentiometer on the backside for adjusting sensitivity. The unit requires 5v DC to operate and can deliver information via its analog and digital pins. Comes with an assortment of Female to Male DuPont Cables. Please wait three minutes after powering the device for accurate readings, it may get hot to touch over a long duration of operation.
