Hi to all,
I'm working on an ADXL354 analog accelerometer with internal temperature sensor; the accelerometer values are ok but I can not correctly convert temperature voltage output in Celsius degrees.
What I make is:
Temperature [°C] = 25 + (Out_Temperature_Voltage [mV] - 892.2) / 3.0
because from datasheet I read the conversion factor is 3.0mV/°C and at 25°C the output voltage is 892.2mV. Using this formula I read very strange values...at room temperature the output voltage is about 974mV that gives me a temperature of 52°C !!!!
Please could anyone tell me what's going on ?
