I am working on PCT2075 temperature sensor.
I have a doubt, From data sheet of PCT2075, Section 7.4.3 indicates, temperature reading of raw data. I am not having problem while reading temperature data up to 125 degrees. But still if I am increasing the temperature on temperature sensor what happen (Eg:130 Degrees), Whether it will show as negative value or the particular register will return as 125 degree value as its temperature sensor is already reached its maximum temperature value.
Did any one tried it.
It will be great if you provide inputs on this.
The max 11-bit Temp data code is 0b011 1111 1111 which corresponds to 127.875 degrees. Higher temperatures will be represented as 0b011 1111 1111 or 127.875 degrees.
Thanks for your response.
But when I tried to increase the temperature more than 127 degrees, I am reading in MSB & LSB bytes via I2C channel are as follows :
10000001 & 10100000.
If possible, could you please test from your side, by increasing temperature more than 127degrees on PCT2075.
In the mean time, I verified I2C Lines of PCT2075 sensor after exceeding +127 degrees, its setting 1st bit of MSB to 1 which indicates negative temperature. Even through temperature sensor is at higher temperature.
Anyone is tried on this, to conform about sensor behavior.
Thanks for your response in advance.
