AVAILABLE STOCK : 8 MENGAPA BERBELANJA DI TOKO KAMI 1. Quick Respond.. OK 2. Quick Delivered.. OK 3. Packed Safely.. OK Description Main chip: LM393, MQ-7 gas sensor. Operating voltage: DC 3-5V. with the signal output indication. the dual signal output (analog output, and TTL level output). TTL output valid signal is low level, can connected to microcontroller directly. 0 ~ 5V analog output voltage, the higher concentration the higher voltage. with high sensitivity and good selectivity for CO. with a long service life and reliable stability. rapid response and recovery characteristics. size: 36mm*24mm*17mm(L * W * H) Application: For CO gas detect, CO detection range: 10 ~ 1000ppm. MQ-7 Sensor Specifications: Detecting Range: 10 to 1000ppm Sensitivity: R in air/R in typical gas5 Response Time150s(70% Response) Recovery Time150s(70% Response) Heating Resistance313 Heating Vlotage5.0V0.2V/1.5V0.1V Heating Power about 350mW Measuring Voltage24V Operating Condition: Ambient Temperature-20 55 Humidity: 95%RH Environment oxygen content: 21% Storage Condition: Temperature: -20 to 70 Humidity: 70%RH Package include: 1 x MQ-7 Sensor Module datasheet: https://www.sparkfun.com/datasheets/Sensors/Biometric/MQ-7.pdf
