for Combustible Gas Sensitive material of MQ-5 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, the sensors conductivity is Higher along with the gas concentration rising. We use simple electro-circuit, convert change of conductivity to correspond output signal of gas concentration. MQ-5 gas sensor has high sensitivity to Methane, Propane and Butane and could be used to detect both Methane and Propane. The sensor could be used to detect different

I'm sure we could use some hypotheses about e-waste. Perhaps something like: Without laws that prevent export of e-waste, it will be exported to countries that lack effective environmental laws/regulation. Processing of e-waste without effective environmental regulations leads to serious toxic pollution by substances like mercury, lead, and dioxins. Burning of e-waste to retrieve metals causes lung disease in the people who do the burning. Smelting e-waste in family cooking pots causes
