We are engaged in providing quality tested Flammable Gas & Smoke Sensors that helps in detecting the presence of combustible smoke and gas at concentrations ranging from 300 to 10, 000 ppm. Due to their simple analog voltage interface, these sensors require just one analog input pin from the micro controller and process the output in the form of analog signals. Our product can work at varied temperature ranging from -20 to 50°C and consume less power, 150 mA to 5 V. Please read the MQ2 datasheet (184k pdf) for more information about the sensor.

Our offered Alcohol Gas Sensor work similar to the common breathe analyzer and used for detecting the concentration of alcohol in breathe. These sensors provide analog resistive output on the basis of alcohol concentration and are highly reckon for their fast response time and high sensitivity. Owing to the simple design, these alcohol gas sensors requires just one resistor for detecting and processing the result.

Some of the features of our product are :

• 5V DC or 5V AC
• Operation Temperature: -10 to 70 degrees C
• Dimensions 16.8mm diameter
• Heater consumption: less than 750mW
• Requires heater voltage
• 9.3 mm height without the pins

Customers can avail from us Methane CNG Gas Sensor for the purpose of sensing natural gas concentrations in the air. Equipped with heater coil of 5V, ADC output and high load resistance, our product is highly acknowledged for its quick response time and high sensitivity. These methane CNG gas sensors are easy to install and can ascertain the natural gas concentrations from a range of 200 to 10000 ppm. This product can be used in conjunction with breakout boards and is available in varied specifications.
