ACS712 5A Range Current Sensor module In Pakistan

MQ7 MQ 7 MQ-7 CO Carbon Monoxide Coal Gas Sensor Module For Arduino detects the concentrations of CO in the air and outputs its reading as an analog voltage. The sensor can measure concentrations of 10 to 10,000 ppm. The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.This module provides both digital and analog outputs. The threshold level for digital output can be easily adjusted using the preset on the board. The MQ-7 sensor module can be easily interfaced with microcontrollers, Arduino, etc.

MQ2 MQ-2 MQ 2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module Smoke LPG Butane Hydrogen Gas Sensor Detector Module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke, or Propane. Due to its high sensitivity and fast response time, the measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by a potentiometer.MQ-2 gas sensor using gas sensitive material is to be clean air in the lower conductivity of tin oxide (SnO2). When the sensor when flammable gases are present in the environment in which the sensor’s conductivity with increasing concentration of combustible gas in the air increases. Use a simple circuit to convert the changes in conductivity and output signal that corresponds to the concentration of the gas.MQ-2 gas sensor higher sensitivity to liquefied petroleum gas, propane, hydrogen, detection of gas, and other combustible vapors are ideal. This sensor can detect a variety of flammable gas, are a low-cost sensor for many applications.

MQ8 MQ 8 MQ-8 Hydrogen Gas Sensor Module For Arduino H2 Alarm Detection MQ-8 Sensor Hydrogen Gas Sensor Module H2 Alarm Detection use in clean air low conductivity tin oxide (SnO2). When there is an environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity, the monitoring of the other hydrogen-containing gas is also very satisfactory. This sensor can detect a wide range of hydrogen gas, city gas, in particular, is a low-cost sensor for a variety of applications.
