CO2 sensor PR51-19

Highlights • - I2C Carbon Dioxide Gas Sensor • - On Board Signal Conditioning Amplifier • - On Board Dual power supply for stable and consistent readings • - 100KHz to 3.4MHz Communication Speed • - Modular MG-811 Breakout Board The MG-811 CO2 Gas Sensor makes it easy to monitor carbon dioxide gas concentration levels using our I2C Mini Module form factor. The MG-811 is connected to an on board signal condition amplifier and the signal amplifier is connected to an ADC121C 12-Bit Analog to Digital converter, which is capable expanding to 9 gas sensors per I2C port using just two address jumpers (making full use of the floating address system). This MG-811 CO2 Gas Sensor is less Sensitive to Carbon monoxide(CO) and Alcohol. This MG-811 CO2 Gas sensor board has dual on board power supply. It has one dedicated 6V power supply for the Gas sensor element and one 5V power supply for Analog interface chip. The MG-811 is capable of sensing carbon dioxide air concentration levels between 350 and 10,000ppm. The ideal sensing condition for the MG-811 CO2 Gas Sensor is 25°C ±2°C at 65% ±5% humidity. An internal preheater inside the sensor helps achieve the ideal sensing conditions, but the datasheet recommends over 48 hours for preheating to achieve optimal accuracy. Because of the internal preheater, this sensor requires more current than most of our I2C Mini Modules. We measured 139ma for this I2C Mini Module so we strongly recommend planning a power strategy for your I2C master device to deliver no-less than 150ma per sensor!
