SENSOR DE GAS CALIDAD DE AIRE, ENSAMBLADO. LISTO PARA USARSE CON ARDUINO, PIC, CYPRESS, ETC...

OJO!!! ES MARCA DFROBOTS, MANEJAMOS UNA MARCA GENERICA CHINA MAS BARATA SI DESEAS.This flammable gas and smoke sensor detects the concentrations of combustible gas in the air and ouputs its reading as an analog voltage. The sensor can measure concentrations of flammable gas of 300 to 10,000 ppm.The sensor can operate at temperatures from -20 to 50°C and consumes less than 150 mA at 5 V. Connections Connecting five volts across the heating (H) pins keeps the sensor hot enough to function correctly. Connecting five volts at either the A or B pins causes the sensor to emit an analog voltage on the other pins. A resistive load between the output pins and ground sets the sensitivity of the detector. Please note that the picture in the datasheet for the top configuration is wrong. Both configurations have the same pinout consistent with the bottom configuration.The resistive load should be calibrated for your particular application using the equations in the datasheet, but a good starting value for the resistor is 20 kΩ.

SENSOR YA LISTO PARA FABRICAR UN ALCOHOLIMETRO, ESTA BASADO EN EL ELEMENTO SENSOR MQ-3. COMPATIBLE CON ARDUINO , PIC, CYPRESS, RASPBERRY, ETC...TAMBIEN MANEJAMOS EL ELEMENTO ACTIVO

OJO!!! es el elemento activo (tambien vendemos el sensor ya ensamblado). This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. .
