How to Build Simple Thermistor Circuits PTC Thermistor Circuit PTCSL03 PTC Thermistor. LM393 Voltage parator. 120ω Resistor. 330ω Resistor. LED. Potentiometer. Thermistors and NTC Thermistors Basic Electronics Tutorials The Thermistor is a solid state temperature sensing device that acts a bit like an electrical resistor but is temperature sensitive. Thermistors can be used to produce an analogue output voltage with variations in ambient temperature and as such can be referred to as a transducer. Thermistors in Single Supply Temperature Sensing Circuits thermistor, the resistance versus temperature circuits depend on the thermistor being operated in a “zero power” condition. This condition implies that there is no self heating of the thermistor as a conse quence of current or voltage excitation. The resis tance versus temperature response of a 10kΩ, NTC thermistor is shown in Figure 3. Thermistor Temperature Sensor Circuit | Sensing Alarm Circuits The element in the circuit that senses the temperature of the environment is a thermistor. The name itself has its meaning. Thermistor means thermal resistor. It means that the resistance of the thermistor varies with change in temperature. The relationship between the resistance of the thermistor and temperature is inversely related. Thermistor Electronic Circuits The circuit draws only a few microamps from a 9 volt battery. It uses a glass bead thermistor accurate to 1 degree C. This electronic hobby circuit below is designed to activate a beeper alarm, whenever the outside air temperature is below 0 degrees C (32F). A 9v battery powers the hobby circuit. How to Build a Simple Thermistor Circuit A PTC thermistor, much less commonly used, is a thermistor whose resistance increases when the temperature it is exposed to increases. In this article, we will use the more common NTC thermistor and build a circuit with the thermistor that can sense temperature changes. When exposed to average room temperature, the LED in the circuit will be off. Make an Arduino Temperature Sensor (Thermistor Tutorial) Thermistors are simple, inexpensive, and accurate components that make it easy to get temperature data for your projects. Remote weather stations, home automation systems, and equipment control and protection circuits are some applications where thermistors would be ideal. Using a Thermistor | Thermistor | Adafruit Learning System Connecting to a Thermistor These thermistors are pretty hardy, you can strip the PVC insulation and stick the wires into a breadboard or solder to them directly. Of course you can cut or extend the wires. Since the resistance is pretty high (10Kohm) the wire resistance won't make a huge difference. NTC thermistors, application notes thermistor and a significant current will flow through the ammeter. It is also possible to use a vari able resistor R3 and to derive the temperature from its resistance value (in balanced condition). An example of a circuit including an NTC thermistor and microcontroller is given in figure 2. Figure 2 Practical application for a circuit How A Thermistor Works Kitronik Introduction: A thermistor is a component that has a resistance that changes with temperature. There are two types of thermistor, those with a resistance that increase with temperature (Positive Temperature Coefficient – PTC) and those with a resistance that falls with temperature (Negative Temperature Coefficient – NTC).
