RhydoLabz s LPG Gas Sensor Module is designed to detect the presence of a dangerous LPG leak in your Home, car or in a service station, storage tank environment by interfacing with Microcontroller without ADC Channels and programming. In this version of LPG Gas sensor module two pots are included, one for trigger level setting and the other for setting sensitivity of the sensor. It allows to determine when a preset LPG gas level has been reached or exceeded. The module uses MQ-6 sensor to sense LPG leak. The MQ-6 can detect gas concentrations ....etc

This is a simple-to-use liquefied petroleum gas (LPG) sensor, suitable for sensing LPG concentrations in the air. The MQ-6 can detect gas concentrations anywhere from 200 to 10000ppm.

This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

This sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board .This c ....etc

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. This type of equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
Gas detectors can be used to detect combustible, flammab ....etc

The P89V51RD2 is an 80C51 microcontroller with 64 kB Flash and 1024 bytes of
data RAM.
A key feature of the P89V51RD2 is its X2 mode option. The design engineer can
choose to run the application with the conventional 80C51 clock rate (12 clocks per
machine cycle) or select the X2 mode (6 clocks per machine cycle) to achieve twice
the throughput at the same clock frequency. Another way to benefit from this feature
is to keep the same performance by reducing the clock frequency by half, thus
dramatically reducing the EMI.
The Flash progra ....etc
