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.

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.

The USB to RS485 Converter Adapter module support WIN7 XP Vista Linux Mac OS provides an easy-to-use RS485 interface by means of a Virtual Com Port on the user’s system. There are no command structures, whatever is sent to the Virtual Comm Port is automatically converted to RS485 and vice versa. The module is completely self-powered from the USB bus. Controlling / Communicating with RS-485 devices from your PC has never been easier! This device is plug-and-play. It shows up as a serial/com port and is accessible from applications or hyper-terminal.
