LCD electronic thermometer circuit
The LCD electronic thermometer circuit employs the ICL7106CD4036 integrated circuit, which is designed for digital temperature measurement applications. The KTY10 temperature sensor is a vital component, known for its accurate and linear resistance-temperature characteristics, making it suitable for precise temperature readings.
In this circuit, the KTY10 sensor converts temperature variations into corresponding resistance changes, which are then processed by the ICL7106. The ICL7106 is a dual-slope analog-to-digital converter that provides high accuracy and stability in measuring the analog voltage output from the KTY10 sensor.
The measurement display circuit, which can be placed up to 100 meters away from the sensor, utilizes a 3-wire connection to minimize signal degradation over distance. This configuration ensures that the digital output remains accurate despite the extended wiring.
The digital display of the thermometer is capable of showing temperatures in the range of -50°C to +150°C, making it suitable for various applications, including environmental monitoring, HVAC systems, and industrial processes. The LCD screen provides a clear and easy-to-read output, which enhances user interaction and data interpretation.
Overall, this electronic thermometer circuit combines precision sensing, effective signal processing, and user-friendly display features, making it a robust solution for temperature measurement needs.Related components PDF download: ICL7106CD4036 The LCD electronic thermometer The LCD electronic thermometer circuit is as shown.
