Temperature control switch (NTC) based on stc microcontroller

Overview

The temperature control switch can be used to control the temperature of heated water or other liquids, and can also be used to control the temperature of the 3D printer hot bed. Temperature adjustment is very convenient. Use a potentiometer to adjust the temperature. When the potentiometer is moving, it displays the adjusted temperature, and when it does not move, it displays the actual temperature. The default program uses a 100kB thermistor with a value of 3950, and the program can change the thermistor to other values. When the output is high, it is heating. You can choose to attach a large MOS tube for direct 12V heating or choose to attach a small MOS tube to drive and then connect an external appliance for heating. It is recommended that the thickness of the proofing board is 1mm, which is more convenient to put into a small box. WeChat picture_20210727170132.jpg QQ picture 20210419001312.jpg
