MQ-7 Semiconductor Carbon Monoxide CO Gas Sensor Module
- Signal output instructions.
- Dual signal output (analog output, and TTL level output)
- The effective signal of TTL output is low level . (when Output lowlevel ,the
- signal light on.can directly connected to the MCU)
- Analog output 0 to 5V voltage, the higher the concentration ,the higher the
- Has a high sensitivity and good selectivity to carbon monoxide .
- Long life and reliable stability
