This multiple enablefunction allows easy parallel expansion to a 1-of-32 (5 to 32 lines) decoder with just four '138 ICsand one inverter
makes the circuit highly tolerant to slower clock rise and fall times
This is a MAX3232-based level shifter for converting TTL-level serial to standard RS-232 serial
Two-wire serial interface
Hydrogen Sensor Module (MQ8) Digital Temperature Sensor This multiple enablefunction allows easyIntroduction: This is a simple to use hydrogen sensor, suitable for sensing hydrogen concentrations in the air. The MQ 8 can detect hydrogen gas concentrations anywhere from 100 10000ppm. This sensor has a high sensitivity and fast response time. Detects Hydrogen(H2), poorly sensitive to LPG, alcohol, cooking steam, CO. Features : Main chip: LM393 Working voltage: DC5V Load resistance: 10K Dual signal output (TTL level output and Analog output) TTL
