Presenting MQ sensors: lowcost 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% dutycycle, by means of such a solution. The sensors ...

KY038 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 (KY028), proximity switch (KY024, KY025, KY036), detecting alarms (KY037, KY ...

How To Use MQ135 Gas Sensor Codrey Electronics

· The datasheet recommends to calibrate the MQ135 sensor for 100ppm NH3 or 50ppm Alcohol concentration in air and use value of the load resistor (RL) about 20KΩ (10KΩ to 47KΩ). But in the MQ135 Chinese module introduced here, we can see a 1KΩ (102) load resistor. Not a good practice of course! So if you want to build a microcontrollerbased trusty air quality monitor yourself with MQ …
