Sell Gas Sensor MQ-135 Air Quality Sensor Module (MQ135) best price

DESCRIPTION Semiconductor sensor Detect the presence Ammonia (NH3) Mono-nitrogen oxides (NOx) Alcohol Benzene Smoke Carbon-dioxide (CO2) Commonly used as an air quality Sensor as it has good sensitivity to harmful gases in a wide range Sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air. Conductivity increases as the concentration of sensing gases increases Easily interfaced with Microcontrollers Arduino Boards, Raspberry Pi etc using an Analog to Digital Converter (ADC) Higher the voltage, the higher the concentration of the analog output voltage SPECIFICATION Able to adjusted by the potentiometer Compatible with Arduino UNO Wide Detecting scope and fast response Simple drive circuit  Stable and long life Dimension: 32mm x 20mm x 22mm Output Digital & Analog Current 150mA Operating Voltage: 5V ± 0.1 Temperature: -10°C to 45°C Heating Voltage 5V ± 0.1 Output Voltage DO: 0V/5V (TTL) AO: 0V - 5V High sensitivity Ammonia Sulphide Benzene Detection NH3 NOx Alcohol Benzene Smoke CO2 ​DOCUMENT Datasheet Example codes Library for Arduino PACKAGE INCLUDE 1 x Gas Sensor MQ-135 Air Quality Sensor Module (MQ135)
