AD620 Instrumentation Amplifier Module In Pakistan

The MQ 135 Air Quality Detector Sensor Module For Arduino has lower conductivity in clean air. When the target combustible gas exists, the conductivity of the sensor is higher along with the gas concentration rising. Convert change of conductivity to the corresponding output signal of gas concentration. The MQ135 gas sensor has high sensitivity to Ammonia, Sulphide and Benzene steam, also sensitive to smoke and other harmful gases. It is with low cost and suitable for different applications such as harmful gases/smoke detection

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.
