NGW-1pc Grove - Multichannel Gas Sensor v2 - Besides CO, NO2, C2H5CH, VOC - MEMS gas sensor

Description Worried about not recognizing the gas around your workplace or other surroundings and environment? Here comes the excellent solutions we offer! Grove - Multichannel Gas Sensor V2 has 4 measuring units, each of which is sensitive to various kinds of gases, which means you are able to get four sets of data at the same time. And different sorts of gases can also be judged by these four sets of data. The gas sensor used in this module is based on MEMS technology and has the advantage of being of a small size with considerable measurement stability and is more suitable for qualitative than quantitative measurement.

Application Indoor Air Quality Monitoring carbon monoxide gas leak alarm Exhaled gas detector indoor smoke alarm
In-vehicle safety: car ventilation control; gasoline vapor detection; alcohol breath test

Specifications

MCU STM32F030 Interface Grove I2C I2C address 0x55 Output voltage 3.3V ~5V Onboard Gas Sensors GM-102B; GM-302B; GM-502B; GM-702B Note Before using it, the sensor needs to be preheated to achieve the internal chemical balance. The preheat voltage is consistent with its heating voltage VH. And the storage time and corresponding warm-up time are recommended as follows: How Does Storage Time Affect The Recommended Warm-Up Time of This Sensor? Storage time Recommended warm-up time Less than 1 month No less than 24 hrs 1-6 months No less than 48 hrs Over 6 months No less than 72 hrs Cautions The module should avoid being placed in the volatile sil
