This Technical Brief presents an example of a simple,
multi-zone thermal monitoring system using the Hard-ware mode of the Master Synchronous Serial Port
(MSSP) module of a PICmicro
®
microcontroller. The
design uses several TCN75 thermal sensors and the
PIC16LF872 microcontroller.
Typical applications where this design may be imple-mented include power supplies, aquariums, personal
computers, work stations, ovens, hot-swappable ther-mal sensing systems, office electronics, and electronic
test equipment. This type of system design is also opti-mum for monitoring temperatures in the electronic sys-tems of various home appliances, such as microwave
ovens, blenders, toasters, refrigerators, washers,
dryers, vacuum cleaners, and mixers.M TB052
Multi-Zone Temperature Monitoring with
the TCN75 Thermal Sensor
Author: Ken Dietz nodes are connected to the host processor through an
Microchip Technology Inc. I2C interface. Only three TCN75 sensors are shown,
to demonstrate the binary addressing scheme using
pins A0 through A2.
