TGS822 50-5000 ppm Alkoholerkennungssensormodul Serieller Port-Ausgang Ethanol-Alkoholgasmessung

Produktbeschreibung

Features
1. With power indicator and threshold alarm indicator
2. Using serial communication, read 0-5V voltage directly from the computer via USB to TTL (the higher the voltage, the higher the concentration)
3. The threshold of 0-5V can be set and compared with the obtained alcohol concentration voltage
4. The alarm polarity can be set. AT+P+1\r\n means the alarm light is on outside the upper and lower threshold
TTL output 1, otherwise output 0; AT+P+0\r\n means the alarm light is on within the upper and lower threshold, TTL output 1, otherwise output 0. Can be directly connected to MCU IO port or relay
5. It has high sensitivity and good selectivity to ethanol vapor
6. Fast response and recovery characteristics
7. Working voltage: 7-12V
Application
1. It is used for on-site detection of motor vehicle drivers and other workers who are strictly prohibited from drinking. It is also used for the detection of ethanol vapor in other places. The detection range of alcohol: detection range 50~5000ppm
2. MCU learning, electronic competition, product development, graduation design, etc.
1. High sensitivity to organic solvents such as ethanol
2. Excellent long-term stability
3. Long-life, low-cost organic solvent detection
1. Alcohol detector
2. Factory, dry cleaner, semiconductor industry
3. Organic solvent detection
