MQ-135 alcohol, benzine, ammonia sensor - semiconductor
Module with sensor MQ-135 detecting benzene, alcohol and smoke. It is powered with the voltage from 2.5 V to 5 V. It has digital and analog output, making it compatible with most commissioning modules, including the Arduino.
We could not load the price.
The promotional price does not combine with quantity discounts.
Description
The sensor detects the concentration of benzene, alcohol and smoke in the air, the result can be obtained measuring the voltage on the analog output. The system is supplied with the voltage from 2.5 V to 5 V. It has a digital and analog output, making it compatible with mostof the commissioning modulesincluding Raspberry PiandArduino.
Specification
- Power supply: from 2.5 V to 5 V
- Analog and digital output
- Pins: goldpin connectors of 2.54 mm raster
- Board sizes: 33 x 20 mm
- It has mounting holes with the diameter: 3 mm
Specifications and other detailed information can be found in thedocumentation.
The product is compatible with Arduino In the web, you can find sample programsforArduinoandSTM32. |
The digital output D0
With the help of the potentiometer placed on the reverse side of the board, set is the threshold above which the output D0 is changed from a high to a low status. The output D0 can be linked directly witha microcontrolleror commissioning set, includingArduino, or for example, with a module of a buzzer which will signal too low or high level of gasesin the air.
Analog output A0
The sensor has an analog output A0 which must be connected to the pin of the converter A/D (of analog input inArduino). This will allow you to measure the proportional voltage signal and more accurately determine the concentration.
