<p>In this paper, a proposal was made to recreate an energy harvesting technique using biomass energy such as twigs, leaves, wood, paper, and charcoal emitted by burning the said materials and harvest the energy from the released heat. The harvested energy is then converted into a voltage that can be used to charge devices such as mobile phones or even turn on emergency lights. In terms of its application, the system can be used to provide backup power during disaster especially during a flood or other causes of power outages. The system can also be used to charge electronic devices during outdoor activities in remote areas where electricity is inaccessible such as camping or other outdoor activities. This system can produce free electric power that can also be extremely beneficial in third world countries. The cost of the module used is also much cheaper than other existing harvesting methods such as solar panels or water turbines. Based on test data collected using IoT platform, charcoal was determined as the best material in terms of output power generated.</p>

“…This kind of flowmeter can be implemented by putting heat marks into the fluid or by continuously driving the heater with an ac signal and measuring the phase shift at the position of the temperature sensor. Most commercial thermal flowmeters are based, mainly, on hot-wire principles but in the scientific literature it is also common to find ones based on calorimetry [4][5][6][7], or using a combination of different thermal principles, for instance: calorimetric and hotwire [8,9] or TOF and calorimetric [10], etc.…”

“…Furthermore, the achievable temperature resolution of typically 0.1 mK enables heater operation at moderate temperatures without significant loss of flow sensitivity. With an appropriate bridge-type arrangement of the thermistors, the sensor can be conveniently read out by pulse-width modulation schemes requiring relatively simple circuits [20]. The performance of such transducers depends largely on their size and thermal inertia.…”

Measurement of air flows is an important task in many process monitoring systems. In applications like control of ventilation and air conditioning systems, robustness, ease of use, and cost are important issues calling for simple and effective sensor design. This paper investigates the use of commercial-off-the-shelf printed circuit board technologies for the fabrication of calorimetric flow sensors. Such sensors are known to be sensitive when being implemented using thin-film technology. The paper reviews the operation principle of thermal flow sensors and their performance in micromachined silicon technology for comparison. Subsequently, a similar design is introduced where heating and temperature sensing elements are made from standard copper traces on a flexible PCB substrate. Simulation studies demonstrate the basic viability of this approach, even if it might entail some performance penalties. First experimental data of sensor prototypes show that the repeatability of the PCB manufacturing processes is basically sufficient for using copper traces as sensors, but leaves also room for future improvement in both technology and sensor design.
