Summary of AT89S52 THERMISTOR CIRCUIT THERMOMETER LCD DISPLAY
This article describes an NTC Thermistor Thermometer project using the AT89S52 microcontroller and HIH-3160 humidity sensor to display temperature and humidity data on an LCD. The circuit supports ADC options like LTC1298 or MCP3202, utilizes P0 for the LCD bus, includes an optional switch (SW1), and allows connection of additional sensors via J2 with a 0 to +5V input range.
Parts used in the AT89S52 Thermistor Thermometer:
- AT89S52 Microcontroller
- NTC Thermistor
- Honeywell HIH-3160 Relative Humidity Sensor
- LCD Display
- LTC1298 or MCP3202 ADC
- P0 Port Interface
- SW1 Key Switch
- J2 Connector

NTC Thermistor Thermometer based on AT89S52 circuit and HIH 3160 humidity sensor humidity and temperature information is given. Display LCD display circuit and there are two versions of the C source code and schema files have been prepared by Orcad.
Thermistor Thermometer: LCD version: The ADC and thermistor circuits are quite the same as the 1st version. The ADC can be LTC1298 or MCP3202. Now with this design, P0 is used to interface LCD bus. SW1 is optional key switch. Since the number of I/O port are not many, we then can replace the 40-pin MCU with 20-pin MCU easily. J2 is available for connecting another sensor. The input range is 0 to +5V. HIH-3160 Honeywell Relative Humidity Sensor
