General Description
The HT7501 is a CMOS digital clinical ther-
mometer IC for measuring body temperature
from 32.00°C~43.00°C. It also provides alarm,
self-test, auto power off and last time measured
temperature functions. The other electronic
components are LCD display, thermister, 1.5V
battery, ON/OFF switch, buzzer, resistors and
capacitors.
