A microwave oven is a cooking appliance that uses food to absorb microwave energy in a microwave field to heat itself. The microwave generated by the microwave generator in the microwave oven establishes a microwave electric field in the microwave oven cavity, and certain measures are taken to make this microwave electric field distribute as evenly as possible in the oven cavity, and the food is placed in the microwave electric field, and the control center controls its cooking time. and microwave electric field strength for various cooking processes.
Capacitive induction touch switches can penetrate more than 20mm of insulating material shell (glass, plastic, etc.), accurately detect the effective touch of fingers, and ensure that the sensitivity, stability and reliability of the product will not change due to environmental conditions. Or change due to long-term use, and has waterproof and strong anti-interference ability.
The essence of a touch screen is a sensor, which consists of a touch detection component and a touch screen controller. The touch detection component is installed in front of the display screen to detect the user's touch position and receive the touch screen controller; the main function of the touch screen controller is to receive touch information from the touch point detection device, and convert it into contact coordinates and send it to the CPU , and can receive commands from the CPU and execute them at the same time.
Touch switch is another successful application of electronics instead of machinery. The touch switch has no metal contacts, no discharge and no ignition, which saves a lot of copper alloy materials and greatly reduces the requirements for mechanical structure. It directly replaces traditional switches and is comfortable to operate, feels great in the hand, precise control and has no mechanical wear. It has been widely used in consumer electronics, kitchen appliances, bathroom appliances, air conditioners and other household appliances, car anti-theft, LED applications, lighting applications, solar photovoltaic applications, audio, mobile terminal tablet computers, smart grids and other fields. Most of the products have been listed and entered the homes of ordinary people.
GT308L is an 8-bit touch sensor series with multi-channel trigger sensor, which provides interrupt function and wake-up function through continuous mode. It features a wide supply voltage range: 2.5V ~ 5.0V, with intelligent sensitivity calibration and embedded GreenTouch3TM engine and embedded CS, EFT enhanced core, with extremely low power consumption (normal standby: 140 ua (@ 3.3V) Normal standby: 160 ua (@5.0V) two types of interface support (1:1 direct output mode; I2C interface mode)
The peripheral circuit is simple and easy to debug; the sensitivity of each button can be adjusted individually through programming, single power supply operation, package (QNF-24L 4 x4; SSOP-24L e0.635) provides interrupt function; LED driver (16-step dimming control ); the sensitivity control is connected through the control pin.
