Hello Sir,
I am using a SHT75 humidity sensor. I am interfacing SHT75 with the
MSP4301232 Microcontroller. The problem I am facing is - after writing the
control byte; the SHT75 does not acknowledge proper receipt of control
byte. I have verified the timings and found them to be good enough. I have
also tried connecting a pull up resistor for the data line, but the SHT75
does not drive the data line low.
I am sending you a snapshot of the CRO display without the pull-up
resistor. Here the data line is low after transmission of the control
byte, but the data line is low after the Microcontroller release the pin
and not by the sensor. I would appreciate if you could explain the problem
behind this.
Also, if you give me some idea of how I would test my Humidity sensor, I
would appreciate.
Regards,
Krishna
