This article explains in detail the application of custom DS18B20 digital temperature sensor in building a digital thermometer. Including working principle, hardware connection, software programming and simulation implementation. Provide complete protues simulation diagram, C source code and result analysis to help readers deeply understand and practice the use of DS18B20.
What are thermistors NTC and PTC?
NTC and PTC are both thermistors, which are special resistors that can change resistance with temperature. They can also be said to be a kind of sensor.
Q: Can you explain sensitivity resolution in more detail? Why are higher values better?
A: High sensitivity eliminates any lead resistance. It also simplifies the supporting electronics. A 10,000 ohm thermistor changes resistance by 4.4% atau 440 ohms for a 1°C change in temperature. A 100 ohm platinum sensor changes resistance by 1/3 ohm for a 1°C change in temperature.
Comparison between PT100 temperature sensor probe and DS18B20 module
1) Basic principle of signal acquisition
① The resistance of PT100 changes proportionally with the temperature (the higher the temperature, the greater the resistance), but the resistance change is very small, about 0.385 Ω / degree;
When many customers buy mechanical bimetal disc thermostat & small thermal protection switch, they will find that even if the parameters of bimetallic temperature control switch are the same, the price of different manufacturers is different. What causes the price of bimetal thermostat switch? Today, the editor will give you a detailed explanation of some factors that affect the price of temperature control switch.

China custom bimetallic thermal cutoff protector switch has surface mount and PC plug-in installation. Thermal Cutoffs switch (bimetallic thermostat) are devices designed to keep components safe in situations when an excessive temperature occurs. List of Select Surface Mount Thermal Switches and Thermal Protectors Product Specs, Datasheets, Manufacturers & Suppliers.
A “3MP / 6AP/ 8AM /2AM / 3MP / 17AM+PTC over current & temp bimetallic protector” is a type of electrical safety device that combines a standard ” 3MP ” bimetallic thermal overload protector with a Positive Temperature Coefficient (PTC) termistor, allowing it to both react to excessive current (overcurrent) and high temperatures, automatically cutting power and resetting once the issue is resolved; essentially acting as a resettable fuse with added temperature protection.
