Talking about the constant temperature cup NTC temperature sensor

In winter, the weather is cold, and the water in the water cup is easy to cool down, and drinking cold water in winter can easily cause physical discomfort. need to keep adding boiling water, which will waste a lot of hot water and cold water.Therefore, in winter, a preservation cup that can continue to constant temperature, constant water temperature.

The constant temperature cup is installed on the cup lid. The lid can be rotated and fixed to the cup body. When the cup lid is rotated on the cup body, the NTC temperature sensor extends into the water, sets on both ends of the cup body, input the power supply side To the stable voltage to the NTC temperature sensor, the NTC temperature sensor can sensor the water temperature and convert the water temperature to the temperature current number value. After the temperature -sensitive current is amplified by the amplifier chip, the temperature simulation voltage signal is converted and entered into the ADC modulus of the microcontroller. In the number conversion interface, the microcontroller is converted to the current water temperature value in the current water cup by collecting digital conversion side voltage signals, realizing the constant temperature of water in the water cup. 

The constant temperature cup NTC temperature sensor is encapsulated with high -sensitive glass seal thermistor and stainless steel probe. It has the advantages of fast response, high temperature resistance, high accuracy, and good stability.
