Butane Hydrogen Gas Sensor Detector Module
Smart Electronics 1pcs MQ2 MQ 2 MQ-2 Smoke Liquefied Flammable Methane Gas Sensor Module for Arduino Diy Starter Kit
Gas may be used in homes and factories leakage monitoring device suitable for the detection of gas, butane , propane , methane , smoke , etc.
- Using high-quality dual-panel design, with power indicator and TTL signal output instructions;
- The switching signal having a DO (TTL) output and analog output AO ;
- TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
- Analog output voltage with the higher concentration of higher voltage.
- A gas, natural gas, city gas , smoke better sensitivity.
- There are four screw holes for easy positioning ;
- Has a long life and reliable stability
- Rapid response and recovery characteristic
Input voltage : DC5V Power consumption ( current ): 150mA
DO output : TTL digital 0 and 1 ( 0.1 and 5V)
AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V
Special note: After the sensor is powered , needs to warm up around 20S, measured data was stable , heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal .
- VCC: positive power supply (5V)
- GND: power supply is negative
- DO: TTL switching signal output
- AO: analog signal output
100% Brand New
1set x MQ-2
Specification: Butane Hydrogen Gas Sensor Detector Module
6 Months Warranty
This item is covered with a supplier warranty of 6 months from the time of delivery against manufacturing defects only. This is a quality product from the original manufacturer. Only manufacturing defects are covered under this warranty. Reimbursement or replacement will be done against manufacturing defects.
What voids the warranty:
If the product is subject to misuse, tampering, static discharge, accident, water or fire damage, use of chemicals & soldered or altered in any way.
Delivery is fast. Quality is super. The store is responsive)
The goods did not come, the store returned the money
The goods have not yet checked.
Went sooo long-three months! But still it came, even a whole.
The sensor looks good, high-quality soldering on the board. But i did not check in the work yet. Delivery to moscow in 17 days.
Thank you. Best store. Recieved fast. I have not checked the item yet.
Fast shipping, the product corresponds to the description. I ordered three sensors, one came damaged. Since it is a sensitive product it should probably be in a box (i.e. Arduino Nano which I also ordered came in a plastic box).
Quality is good! The store is good, i always buy from him! But the mail took the goods for a very long time.
Super fast delivery to ukraine
