MEMS Alcohol Sensor ZM03

  • GM-102B.png


The digital alcohol module is a low-power, miniaturized module. The module uses a combination of a semiconductor gas sensor and a high-performance microprocessor to detect the gas concentration in the environment. The module has high sensitivity, small size and precision, and adopts I2C digital signal output mode, which is convenient for users to use and debug, and greatly shorten the user's design and development cycle. The module can be widely used in many fields such as environmental safety and portable instruments.

Alcohol Detector

Strengthen the punishment of drinking and driving in all the country to reduce the vicious traffic accidents caused by drunk driving. This involves testing a person's alcohol level and using equipment to do the testing. An alcohol detector is an effective tool for measuring the alcohol content in the human body.



Smart refrigerators are constantly innovating in the cross-border integration of different technologies. The addition of food freshness, human body induction, CO2 modules, allowing temperature control, ingredients management, automatic sterilization, intelligent alarm and other functions to continuously refresh the market for reconstructing future life style.

All the Mc Series Products Measure Combustible Gas, What is the Difference?

MC series products are different in power supply voltage and current, their appearance and structure are also different; in addition, they are divided into two types: domestic and industrial. Industrial products require explosion-proof and the shell should be the explosion-proof structure of metallurgical powder mesh. The MC100 series is mainly used for domestic use, and the MC110 series is mainly used for industry.

What is the Reason for the Early Warning of the Catalytic Sensor?

The sensor has a long cooling time and insufficient aging. The test conditions and environmental conditions for inspection and calibration are different. The vibration during use causes the zero point changing. It is activated by high-concentration gas during use, then the sensitivity becomes higher.

The Reason Why the Catalytic Sensor Has No Signal Output?

1) The vibration during transportation or use causes the sensor to broken wire; 2) High voltage or short circuit burnout.
