· 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 ...

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 ...
MQSeries ist eine plattformunabhängige Message orientierte MiddlewareSoftware (MoM) des Unternehmens IBM, die 1992 eingeführt wurde und auf dem Prinzip des Message Queueing basiert. Das Produkt wurde von IBM eine Zeitlang unter der Bezeichnung „WebSphere MQ“ und derzeit als IBM MQ vertrieben. Diese Seite wurde zuletzt am 4. Oktober 2019 um 11:22 Uhr bear
· Die GasSensoren der MQSerie benutzen ein kleines Heizelement mit einem elektronischchemischen Sensor. Sie sind empfindlich gegenüber verschiedenster Gase und eignen sich zur Verwendung in Räumen. Die Sensoren sind anschlussfertig für einen …
· 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 …
The gas sensitive material used in the MQ2 gas sensor is SnO2, a low electrically conductive material in clean air. When there is combustible gas in the surrounding air, the electrical conductivity of the sensor will increase with the higher intensity of the combustible gas.
