FITUR DAN SPESIFIKASI : - With a signal output instructions. - Dual signal output (TTL level output and analog output) - TTL output valid signal for low level. (when the low output electric signal lights at 4. ordinary times, can be directly pick up SCM) - Analog 0 ~ 5 v voltage, the higher the concentration, the higher the voltage. - High sensitivity to hydrogen - Can be resistant to ethanol steam, LPG (petroleum), smoke interference - Has a long service life and reliable stability - Quick response recovery features - Size: 32 mm X22mm X27mm - Main chip: the LM393, MQ-8 gas sensor - Working voltage: DC5V
