Development of wireless sensor network for combustible gas monitoring

Optimization of power consumption for gas sensor nodes: A survey

“…Sensor nodes based on catalytic and semiconductor sensors [7] [8] consume less power than the nodes with an optical gas sensor on board. At the same time they are characterized by quick response and good selectivity.…”

Energy Harvesting for Wireless Sensor Networks Review

“…Monitoring of hazardous gases is one of the areas where wireless sensors have been used [1]. Systems based on wires have some disadvantages as being dependent on power supply, high maintenance costs, sometimes electrical power supply cut off occurrence, and long deployment time.…”

“…However, there are some advantages and disadvantages associated with each method. The deployment costs for using satellites are high [1] and due to the orbital limitations not all satellites can monitor a fire event continuously [5]. Limitations of using aircrafts can arise in some areas which are prone to low altitude clouds and this can cause more obstacles in terms of visibility [5].…”

“…The high power consumption of combustible gas detection systems is a restricting factor which needs to be considered [8], [9]. Sensors designed for this purpose and having on board batteries cannot have a long time life cycle [1] and moreover in some applications like structural health monitoring of critical infrastructures and buildings, it is difficult to replace or recharge batteries [10]. As mentioned in [11], some sensor networks like BAN systems require low energy levels.…”

Wi-Fi Wireless Digital Sensor Matrix for Environmental Gas Monitoring

“…These platforms require frequent recalibration and may result in inaccurate gas measurement, because only one sensor can be used in sensing circuit and because of neglecting environmental effects [3]. Another similar example of wireless sensor -actuator system for gas leak detection with single catalytic sensor was demonstrated in [4][5]. Upon detection of a dangerous gas in the environment, the sensor node communicates to a remote actuator in wireless way using ZigBee/IEEE802.15.4 standard and BACnet protocol.…”
