Facing problem in MH-Z16 CO2 sensor with Arduino Board

Post by santanucse16 » Fri Oct 26, 2018 3:45 pm

Hello,
I have bought this MH-Z16 CO2 sensor and now I have problems to receive data from the sensor, I have connected this sensor with Arduino MEGA board with shield(UART/I2C).
I have run the code from http://wiki.seeedstudio.com/Grove-CO2_Sensor/ and get the output but all the 9 values get the same output at a time, there will be no change and after refreshing the serial monitor output I get the another result but all are same.

I have attached the output page below.

Please help me out from this problem as soon as possible.
