Arduino Infrared Remote in Pakistan

The MQ135 MQ-135 MQ 135 Air Quality Detector Sensor Module For Arduino has lower conductivity in clean air. When the target combustible gas exists, the conductivity of the sensor is higher along with the gas concentration rising. Convert change of conductivity to the corresponding output signal of gas concentration. The MQ135 MQ-135 MQ 135 gas sensor has a high sensitivity to Ammonia, Sulphide and Benzene steam, also sensitive to smoke and other harmful gases. It is at low cost and suitable for different applications such as harmful gases/smoke detection.

The heart rate sensor module MAX30100 is an integrated pulse oximetry and heart rate monitor sensor solution. Heartbeat sensor combines two LEDs, the photodetector, optimized optics. This best heart rate module is low-noise analogue signal processing to detect pulse oximetry and heart-rate signals.

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.
