  • Analog CO/Combustible Gas Sensor(MQ9)
    INTRODUCTION The MQ-9 Analog Gas Sensor has high sensitity to Carbon Monoxide, Methane and LPG. The sensor can be used to detect different gases containing CO and combustible gases, it is low cost and suitable for a variety of applications.  The core sensing material of MQ-9 gas sensor is SnO2, which has a lower conductivity in clean air. It makes detection by cycling high and low temperature, and detects CO when low temperature (heated by 1.5V). The sensor’s conductivity is higher along with the gas concentration rising. When temperature rises (heated by 5.0V), it detects Methane, Propane, combustible gas,etc  and cleans the other gases adsorbed under low temperature.    Notice:The new version of anal..

  • Analog Grayscale Sensor V2
    INTRODUCTION The gray-scale sensor is a composition of a photocell (light-controlled variable resistor) and a integrated white LED on board aiming just front of the sensor. With this sensor you can measure ambient light directly from voltage using Analog read pin on your Arduino IDE. It's connected LED will let you compare and provide some reflective feedback to analyse gray scale light ranges. Different colors will apply but only gray scale values will be outputted. This new design includes a much better quality connector that increases life span of the sensor, better voltage range and easy to use.  This is a common sensor for automatic lamps that are turned on when light is not enough. For example, with lack of sun light th..
