Presenting MQ sensors: low-cost gas and pollution ...

· As for some MQ sensors, the heater is powered at 2V: a low and atypical voltage, that we might obtain by using a PWM technique, starting at 5V; in practice we would drive a pulse heater (whose pulse length would be varied), along with a circuit that is based on a PWM modulator. In theory, we should be able to generate 5 V pulses with a 40% duty-cycle, by means of such a solution. The sensors ...

KY-038 Microphone sound sensor module - SensorKit X40 Wiki

This sensor doesn't show absolute values (like exact temperature in °C or magneticfield strenght in mT). It is a relative measurement: you define an extreme value to a given normal environment situation and a signal will be send if the measurement exceeds the extreme value. It is perfect for temperature control (KY-028), proximity switch (KY-024, KY-025, KY-036), detecting alarms (KY-037, KY ...
