CH201 no acknowledgement

By arulkumar107gmailcom , 18 June 2021

Hi there,
I'm working on CH201 sensor, the sensor didn't respond for the program address(0x45) mention on the datasheet.
I make check on the I2C bus and as well as in coding also, there is no issue. Both Reset and Program pins are high on trying to communicate.
Can any one know help me out from this issue.
