The control circuit DS1621 application with which we have previously circuit ( PIC16F84A temperature fan control with LCD display -55 ° C / +125 ° C Picbasic ) TCN75 carried out with heat sensor state.
And we use this circuit to TCN75 DS1621 temperature sensor is a PIN to PIN . For this reason, we use the previous circuit , I use the same printed circuit board . A TCN75 , DS1621 easier than a sensor .
That is; I2CWRIT to read the DS1621 with the command to configure the device after posting DEGREE able to read , TCN75 not apply to this case . Their default values directly in the sensor reading is set up can be done . As can be seen from the program for DS1621 written as three lines of command is a single line for TCN75 .
In my research on the net I could not find TCN75 circuit made with ( perhaps I may not have found are : D) sensor not as DIP , SOIC present case . SOIC to DIP case I use the converter
