Temperature To Voltage Converter Circuit

This is a simple temperature to voltage converter circuit or an electronic thermometer circuit there.

Temperature to voltage converter circuit.

The circuit operates at 6v power supply an ntc negative temperature coefficient thermistor or temperature variable resistor is used as a sensor that has a strong temperature dependence. The gain pot and r2 may be tweaked and experimented for achieving the desired temperature to voltage ratio. With this simple temperature to voltage converter circuit we can do a precise measurement of the temperature in a room. Lm334 which can be a accuracy temperature sensor chip is set up with another accuracy voltage regulator ic lm317 circuit developing a precise linear temperature to voltage converter circuit.

With this simple temperature to voltage converter using thermistor 741 circuits you can do a precise measurement of the room temperature. Temperature to voltage converter is a device which converts each degree rise in ambient temperature into a corresponding rise in the output voltage from the device. The gain pot and r2 might be changed and experimented for attaining the preferred temperature to voltage ratio. In this circuit if the thermistor detects temperature.

Lm334 which is a precision temperature sensor chip is configured with another precision voltage regulator ic lm317 circuit forming an accurate linear temperature to voltage converter circuit. If the ntc temperature rises then the output voltage rises with 0 5 v per 1 0 c. It is easy to build the circuit of temperature to voltage converter having a range between 0 to 24 celsius ranges of temperatures. Which will operate in a temperature range of 0 to 24 degrees celsius 32 to 75 degrees fahrenheit.
