See the simple DC bridge circuit shown in the figure for precision measurements using thermistor manufacturers. The correct choice of resistors R2 and R3 will eliminate the average DC value of V. Simple DC bridge circuit diagram....
Choosing the right temperature sensor not only saves money, but also maximizes system performance. In this blog post, I will mainly talk about thermistors and analog temperature sensors, both of which are cost effective temperature sensing s....
The DS18B20 is a commonly used temperature sensor chip that occupies only one IO port of the microcontroller and is especially convenient to use. It is important to note that because it only uses one IO port to communicate with the MCU, the....
Keywords: temperature sensor circuit The temperature generator is powered by a miners lamp battery, and the principle that the NTC thermistor is reduced in temperature due to temperature rise and the heating drive current is reduced by feedb....
The main component of the thermistor sensor is a thermistor. When there is heat radiation around the heat sensitive material, it absorbs the radiant heat, causing an increase in temperature, causing a change in the resistance of the material....
PTC thermistors can be used in computers and their peripherals, mobile phones, battery packs, telecommunications and network equipment, transformers, industrial control equipment, automotive and other electronic products. As a switch type PT....
PTC (Polymer Positive Temperature Coefficient) devices help protect against overcurrent surges and overtemperature faults. Thermistor-type devices limit dangerous high currents under fault conditions. But it is different from the traditional....
Keywords: PTC The security power supply has two outputs and multiple outputs. The single output power supply is an independent power supply and is only suitable for independent camera power supply. For multi-camera systems, it is not practic....
Ultrasonic nebulizers and humidifiers are new products in recent years. Their working principle is to generate shock through the atomizing sheet, and the liquid changes from liquid to gas under the action of the atomizing sheet. Humidifiers....
In view of the unstable factors in the power supply circuit, the circuit designed to prevent such unstable factors from affecting the circuit is called a protection circuit. In all kinds of electronic products, protection circuits abound. Fo....
