Ozone gas detection sensor unit MQ131

TTL output signal low level; (the signal light illuminates when the output is low, and it can be connected to the input/output port of the microcontroller) increasing the analog output voltage with increasing focus. The more the focus, the higher the voltage. Dual signal output (analog output and TTL level output) with signal output indicator long lifespan and reliable stability fast response with mounting holes for easy installation probe can be connected and disconnected for easy testing operating voltage: 5V DC focus verification: 10ppb-1000ppb size: 35mm*22mm*30mm
