Features：
Size: 32X20X22mm/1.25*0.78*0.86”
The main chip: MQ-4 gas sensing probe
Operating voltage: DC 5V
Power (current) : 150mA
DO Output: 0.1V/5V
AO Output: 0.1-0.3V
Indication of the signal output
Dual signal output (analog output, and TTL level output)
TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.
Of methane gas, the natural gas has better sensitivity
Applications:
Suitable for home or factory methane gas, natural gas, and other monitoring devices

Purchasing & Delivery
Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.Delivery
