General Descriptions

CH2115S is a CMOS digital clinical thermometer IC for measuring body temperature in Centigrade(℃) or Fahrenheit(℉) mode by its bonding option or by switch option. It also provides alarm and auto power off functions. The other electronic components are LCD display, thermistor,1.5V battery, ON/OFF switch, buzzer, resistors and capacitors
