CP2102 chip from SiLabs is a single-chip USB to UART bridge IC. This cp2102 USB to serial requires minimal external components.CP2102 can be used to migrate legacy serial port based devices to USB.

MQ-6 LPG/Butane Gas Sensor Module MQ-6 LPG/Butane Gas Sensor Module gas sensor detects the concentrations of LPG, isobutane, and propane in the air and ouputs its reading. Buy online in Pakistan.

MQ8 MQ 8 MQ-8 Hydrogen Gas Sensor Module H2 Alarm Detection MQ-8 Sensor Hydrogen Gas Sensor Module H2 Alarm Detection use in clean air low conductivity tin oxide (SnO2). When there is the environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity, the monitoring of the other hydrogen-containing gas is also very satisfactory. This sensor can detect a wide range of hydrogen gas, city gas, in particular, is a low-cost sensor for a variety of applications.
