Mosquito coil - Wikipedia- qualities of a mosquito coil control circuit ,Mosquito coil A mosquito coil is a mosquito-repelling incense , usually made into a spiral, and typically made using dried paste of pyrethrum powder. The coil is usually held at the center of the spiral, suspending it in the air, or wedged by two pieces of fireproof netting to allow continuous smoldering.Semiconductor Ceramics In Our Lives - Mingrui CeramicsA gas alarm is now installed in the kitchen. Once there is a gas leak, it will automatically flash and buzz to warn people to take immediate measures. The ceramics whose resistance varies with the concentration of alcohol vapor can be used to make wine-sensitive sensors. The sensor is installed on the car's engine control circuit.
