SRF05 Ultrasonic Module Features
SRF05 is an ultrasonic transmitter and receiver module used to measure distance. The sensor operation is very simple. You only need to measure the return time of ultrasonic waves in order to measure the distance. Then you should divide measured time by 2 and multiply by the sound speed. The sensor measuring range is about 2 to 400 cm.

MQ-7 Smoke Gas Module Features
MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kinds of gas combinations. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is needed. Gas sensor is an indoor module and is used at room temperature. The MQ-7 sensor has high sensitivity to Carbon Monoxide and is able to detect the concentration of carbon monoxide in the air. The measurable concentration range of this s...
MQ-8 Hydrogen Gas Sensor Features
MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kind of gases combinations. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is needed. The MQ-8 hydrogen gas sensor is suitable for sensing hydrogen concentrations in the air. The MQ-8 can detect hydrogen gas concentrations anywhere from 100-10000ppm. This sensor has a high sensitivity and fast response time.
