The MF522-AN module adopts MFRC522 original reader circuit chip design
Differs from the last version the Grove - Light Sensor (P) v1
MQ3 Alcohol Detector Gas Sensor printer the higher voltageFeatures: High quality double panel design, with power indicator and TTL output signal. Have DO switch signal(TTL) output and AO analog signal output. TTL output signal for low level effectively. (when the low output electric signal lights at ordinary times, can directly connect single chip microcomputer or relay module) Analog output voltage with concentration, the higher concentration, the higher voltage. Has better sensitivity with the liquefied
