CJMCU-0201 Double Touch Sensor Features A touch sensor is a type of switch that only has to be touched by an object to operate. Touch sensors work completely similar to a switch. This sensor has two separate pads and can be used as two separate switches. Note When this switch is subjected to touch, the output voltage will be HIGH, otherwise it is LOW. Note The output current is very low (about 40 mA). If you want to connect a higher current device to this switch, you must add a rela...

Introduction Thermometers and temperature sensors are widely used in many sectors. With advancements in science and technology, different methods and sensors have been developed to measure temperature. These sensors are used in various areas, including industry, homes, labs, and more. Many of these sensors and modules are designed for easy integration with microcontrollers and microprocessor systems.
